[Coverage of complex pararectal pelvic defects: role of the free myocutaneous musculus vastus lateralis flap]. / Deckung komplexer pararektaler Beckendefekte: Rolle der freien myokutanen Musculus vastus lateralis Lappenplastik.

BACKGROUND: In the event of an advanced rectal carcinoma, an evisceration with rectal amputation may become necessary. The resulting defects, due to their extent, depth, or local tissue damage from previous surgeries and radiation, can in many cases only be closed through free microvascular tissue transfer. In this case series, we demonstrate the successful combination of a musculocutaneous musculus vastus lateralis flap (MVL) with a direct connection to the superior gluteal artery. MATERIALS AND METHODS: Over a 47-month period, we retrospectively examined 11 cases of patients with dorsal pelvic defects after evisceration and rectal amputation that could not be closed using local or regional means. In cases of extensive defects with deep pararectal wound cavities, all these patients underwent defect coverage through a free myocutaneous MVL flap with a direct vascular anastomosis to the superior gluteal vessels. RESULTS: The mean defect size was 290.0 cm² (SD: 131.2; range: 200-600 cm²). The mean defect depth was 10.5 cm, necessitating MVL flap reconstruction with an average size of 336.3 cm². Three operative revisions were required due to postoperative bleeding. There were no arterial or venous thromboses, and no flap loss occurred. Only one necrosis of a distal flap tip was observed, which could be corrected secondarily by direct suturing. The case-mix evaluation yielded an average value of 24.251 (SD: 21.699; range: 7.036-65.748) points, emphasizing the complexity of the cases. CONCLUSIONS: Our results indicate that a free microvascular MVL flap is a viable therapeutic option for pararectal defects that cannot be closed by local or regional methods. The superior gluteal artery proves to be a safe and sufficient vascular connection. In combination, even extensive defects can be successfully closed.

[Clinical effects of flaps or myocutaneous flaps transplantation after titanium mesh-retaining debridement in repairing the wounds with exposed titanium mesh after cranioplasty].

Objective: To explore the clinical effects of flaps or myocutaneous flaps transplantation after debridement to repair the wounds with exposed titanium mesh after cranioplasty on the premise of retaining the titanium mesh. Methods: This study was a retrospective observational study. From February 2017 to October 2022, 22 patients with titanium mesh exposure after cranioplasty who met the inclusion criteria were admitted to the Department of Plastic, Aesthetic & Maxillofacial Surgery of the First Affiliated Hospital of Xi'an Jiaotong University, including 15 males and 7 females, aged from 19 to 68 years. After admission, treatments such as bacterial culture of wound exudate sample, anti-infection, and dressing change were carried out. Thorough surgical debridement was performed when the wound improved, and the wound area was 3.0 cm×2.0 cm to 11.0 cm×8.0 cm after debridement. The wound was repaired with local flaps, expanded flaps, or free latissimus dorsi myocutaneous flaps according to the size, location, severity of infection, and surrounding tissue condition of the wounds, and the areas of flaps or myocutaneous flaps were 5.5 cm×4.0 cm to 18.0 cm×15.0 cm. The donor areas of flaps were sutured directly or repaired by split-thickness skin grafts from head. The wound repair method was recorded. The survivals of flaps or myocutaneous flaps after surgery and wound healing in 2 weeks after surgery were recorded. During postoperative follow-up, recurrence of infection or titanium mesh exposure in the implanted area of titanium mesh was observed; the head shapes of patients, scar formation of the operative incision, and baldness were observed. At the last follow-up, the satisfaction of patients with the treatment effect (dividing into three levels: satisfied, basically satisfied, and dissatisfied) was evaluated. The total treatment costs of patients during their hospitalization were calculated. Results: The wounds in 11 cases were repaired with local flaps, the wounds in 5 cases were repaired with expanded flaps, and the wounds in 6 cases were repaired with free latissimus dorsi myocutaneous flaps. All flaps or myocutaneous flaps survived completely after surgery, and all wounds healed well in 2 weeks after surgery. Follow up for 6 to 48 months after operation, only one patient with local flap grafting experienced a recurrence of infection in the titanium mesh implanted area at more than one month after surgery, and the titanium mesh was removed because of ineffective treatment. Except for one patient who had a local depression in the head after removing the titanium mesh, the rest of the patients had a full head shape. Except for myocutaneous flap grafting areas in 6 cases and skin grafting area in 1 case with local flaps grafting had no hair growth, the other patients had no baldness. All the scars in surgical incision were concealed. At the last follow-up, 19 cases were satisfied with the treatment effects, 2 cases were basically satisfied, and 1 case was dissatisfied. The total treatment cost for patients in this group during hospitalization was 11 764-36 452 (22 304±6 955) yuan. Conclusions: For patients with titanium mesh exposure after cranioplasty, on the premise of adequate preoperative preparation and thorough debridement, the wound can be repaired with appropriate flaps or myocutaneous flaps according to the wound condition. The surgery can preserve all or part of the titanium mesh. The postoperative wound healing is good and the recurrence of infection or titanium mesh exposure in the titanium mesh implanted area is reduced, leading to good head shape, reduced surgical frequency, and decreased treatment costs.

[Preliminary application of foldable pedicled latissimus dorsi myocutaneous flap for repairing soft tissue defects in shoulder and back].

Objective: To explore the feasibility and effectiveness of a foldable pedicled latissimus dorsi myocutaneous flap to repair soft tissue defects in the shoulder and back. Methods: Between August 2018 and January 2023, the foldable pedicled latissimus dorsi myocutaneous flaps were used to repair soft tissue defects in the shoulder and back of 8 patients. There were 5 males and 3 females with the age ranged from 21 to 56 years (mean, 35.4 years). Wounds were located in the shoulder in 2 cases and in the shoulder and back in 6 cases. The causes of injury were chronic infection of skin and bone exposure in 2 cases, secondary wound after extensive resection of skin and soft tissue tumor in 4 cases, and wound formation caused by traffic accident in 2 cases. Skin defect areas ranged from 14 cm×13 cm to 20 cm×16 cm. The disease duration ranged from 12 days to 1 year (median, 6.6 months). A pedicled latissimus dorsi myocutaneous flap was designed and harvested. The flap was divided into A/B flap and then were folded to repair the wound, with the donor area of the flap being pulled and sutured in one stage. Results: All 7 flaps survived, with primary wound healing. One patient suffered from distal flap necrosis and delayed healing was achieved after dressing change. The incisions of all donor sites healed by first intention. All patients were followed up 6 months to 4 years (mean, 24.7 months). The skin flap has a good appearance with no swelling in the pedicle. At last follow-up, 6 patients had no significant difference in bilateral shoulder joint motion, and 2 patients had a slight decrease in abduction range of motion compared with the healthy side. The patients' daily life were not affected, and linear scar was left in the donor site. Conclusion: The foldable pedicled latissimus dorsi myocutaneous flap is an ideal method to repair the soft tissue defect of shoulder and back with simple operation, less damage to the donor site, and quick recovery after operation.

Extended arc of rotation of Latissimus Dorsi Musculocutaneous Flap providing well-vascularized tissue for reconstruction of complete defects of the sternum: An anatomical study of flap pedicle modification.

BACKGROUND: Deep sternal wound infections (DSWI) following cardiothoracic surgery represent a life quality endangering sequelae and may lead to sternal osteomyelitis. Radical debridement followed by Negative Pressure Wound Therapy (NPWT) may achieve infection control, provide angiogenesis, and improve respiratory function. When stable wound conditions have been established a sustainable plastic surgical flap reconstruction should be undertaken. OBJECTIVE: This study analyses a method to simplify defect coverage with a single Latissimus Dorsi Myocutaneous Flap (LDMF). METHODS: Preparation of 20 LDMF in ten fresh frozen cadavers was conducted. Surgical steps to increase pedicle length were evaluated. The common surgical preparation of LDMF was compared with additional transection of the Circumflex Scapular Artery (CSA). RESULTS: Alteration of the surgical preparation of LDMF by sacrificing the CSA may provide highly valuable well-vascularized muscle tissue above the sensitive area of the Xiphisternum. All defects could be completely reconstructed with a single LDMF. The gain in length of flap tissue in the inferior third of the sternum was 3.86±0.9 cm (range 2.2 to 8 cm). CONCLUSIONS: By sacrificing the CSA in harvesting the LDMF a promising gain in length, perfusion and volume may be achieved to cover big sternal defects with a single flap.

Soft tissue Reconstruction Using Pedicled Trapezius Musculocutaneous Flap for Cranial Bone Flap Infection in the Occipital Region.

When managing cranial bone flap infections, infected bone flaps are typically removed and subsequently replaced with artificial bones 6 to 12 months after the inflammation subsides. However, defects in the occipital region pose challenges due to concerns regarding brain protection when patients lie in the supine position. Herein, the authors report the case of a 73-year-old woman with an occipital bone flap infection, which was successfully managed by reconstruction with a trapezius musculocutaneous flap immediately after removing the infected bone flap. One year and 2 months postoperatively, the wound had fully healed, and the patient remained symptom-free without any complications, such as sunken flap syndrome. Soft tissue reconstruction using pedicled trapezius musculocutaneous flap is a viable strategy for managing occipital bone flap infections. This flap ensures stable blood flow and requires minimal vascular manipulation, thereby reducing operation time as the patient does not need to change position.

Soft tissue reconstruction of the trunk with pedicled perforator and musculocutaneous flaps: A single-center comparative retrospective study.

BACKGROUND: Soft tissue trunk reconstruction is often challenging. Although free microvascular flaps are a feasible option in case of extensive defects involving deep structures, pedicled flaps represent a good alternative, especially if harvested and dissected with a "microsurgical" approach. The aim of this study is to evaluate the feasibility of trunk reconstruction with the use of pedicled flaps, according to the application of our reconstructive algorithm, and to compare it to other reconstructive methods. PATIENTS AND METHODS: From January 2017 to December 2021, we retrospectively analyzed patients who underwent soft tissue reconstruction of the trunk with pedicled flaps at the authors' institution. Patient's demographic, clinical and surgical characteristics and postoperative complications were recorded and analyzed by descriptive statistics. A comparative analysis was made between the study group and two other groups who underwent reconstruction of trunk defects with free flaps and skin grafts, respectively, at the authors' institution. RESULTS: Forty-seven patients were included in the study. Patients' age ranged between 36 and 82 years (mean: 57.8 years). Twenty-eight patients were male, while 19 patients were female. In 76.6% of patients (36 out of 47), reconstructive procedures were performed to repair defects resulting from cancer resection. Reconstruction of superficial defects was always achieved with perforator flaps (n = 25). In case of full-thickness defects, reconstruction was carried out with musculocutaneous flaps (n = 22); latissimus dorsi and vastus lateralis were the most used flaps for chest and abdominal wall reconstruction, respectively. In our series, we observed only one case of total flap loss requiring re-operation under general anesthesia. Minor complications occurred in 8.5% of cases (4 out of 47 patients). We observed two cases of partial flap necrosis and two cases of wound dehiscence. In the skin grafts group (n = 53), the mean age was 54.5 years (range 39-85) and 56% of patients were male (n = 30). In 66% of cases (n = 30) the defect resulted from oncological resection. The overall complication rate was 18.8% (n = 10). In the free flaps group (n = 10), the mean age was 49.0 years (range 29-77) and 60% of patients (n = 6) were male. In 70% of cases (n = 7) the defect was caused by oncological resection. Complications occurred in two patients (20%). No statistically significant differences were found in terms of overall complication rate between the study group and the two comparative groups (p = .48). A significant correlation was found between the reconstructive method and the type and size of the defect, with reconstruction through free flaps being associated with larger (344.0 vs. 220.4 cm2 ) (p = .04) and full-thickness defects (80.0% vs. 46.8%) (p < .01) if compared to pedicled flaps. CONCLUSIONS: In the new era of microsurgery, pedicled flaps represent a valid alternative to free flaps for the majority of soft tissue defects of the trunk. In our series, no statistically significant differences in terms of complications were found between reconstructions of similar defects achieved with pedicled and free flaps, and free flap use was limited to extensive full-thickness defects. In addition, the rate of postoperative complications with pedicled flaps found in our cohort was lower than the rate reported in the literature.

Introduction and preliminary application report for a novel 3D printed perforator navigator for fibular flap surgery.

The aim of this study was to introduce and report on a 3D-printed perforator navigator and its clinical application. Integrated imaging and 3D printing techniques were employed for the design and manufacture of a perforator navigator. Key techniques included establishing a digital image coordinate system, localizing perforator fascia piercing points, creating a reference plane for the perforator course, and projecting the perforator course onto the body surface. All cases of maxillofacial defect repaired with free fibular myocutaneous flaps, from January 2019 to January 2022, were reinvestigated. Patients treated using traditional perforator localization methods were assigned into group Ⅰ, while those who had a navigator used during treatment were allocated to group Ⅱ. Outcome measurements included perforator positioning accuracy, perforator preparation time (PT), and flap growth score. Capillary refilling time and degree of flap swelling were recorded on the 1st, 3rd, and 7th days after surgery. On the 10th day after surgery, the flap survival situation was graded. In total, 25 patients were included in the study. Perforator preparation time for group Ⅱ was significantly less (p ＝ 0.04) than for group Ⅰ (1038.6 ± 195.4 s versus 1271.4 ± 295.1 s. In group Ⅱ, the mean positioning deviation for the perforator navigator was 2.12 cm less than that for the high-frequency color Doppler (p ＝ 0.001). Group Ⅱ also had a higher score than group Ⅰ for overall flap growth evaluation (nonparametric rank sum test, p ＝ 0.04). Within the scale of the study, it seems that perforator localization and navigation using a 3D-printed navigator is technically feasible, and helps to improve the clinical outcome of free fibular flaps. The perforator navigator will play a useful role in displaying the perforator course, improving the accuracy of perforator localization, reducing surgical injury, and ultimately enhancing flap success rate.

Successful Closure of a Persistent Enterocutaneous Fistula with a Myocutaneous Flap.

Enterocutaneous fistulas can present with significant morbidity and mortality for affected patients, as the abnormal connection can result in exorbitant loss of enteral fluids, electrolyte disturbances, and sepsis, among other complications. We present a patient with a chronic complex enterocutaneous fistula who underwent several surgeries, resulting in a considerable amount of bowel resection. Based on history and findings of high output fistula with diverting transverse colostomy, the fistula was closed with a left rectus myocutaneous pedicle flap to avoid entering the abdominal cavity and prevent the possibility of short bowel syndrome. This case contributes to the growing body of literature supporting the use of rectus myocutaneous flaps for the closure of intractable complex enterocutaneous fistulas in patients unable to undergo resection of the affected bowel.

[Clinical effects of different types of tissue flaps in repairing the wounds with steel plate exposure and infection after proximal tibial fracture surgery].

Objective: To investigate the clinical effects of different types of tissue flaps in repairing the wounds with steel plate exposure and infection after proximal tibial fracture surgery. Methods: A retrospective observational study was conducted. From January 2015 to December 2021, 11 patients with steel plate exposure and infected wounds after proximal tibial fracture surgery who met the inclusion criteria were admitted to Jiangxi Provincial General Hospital of Armed Police, including 9 males and 2 females, aged 26 to 61 years. The wounds were located on the lateral side of the proximal leg in 5 cases, on the medial side of the proximal leg in 2 cases, and on the medial side of the proximal leg and the anterior tibia below the knee in 4 cases. After debridement, the wound area was 14 cm×6 cm-22 cm×11 cm. The wounds were repaired with different types of tissue flaps, and the steel plates were removed immediately if necessary, according to the infection around the steel plates. The reverse anterolateral thigh myocutaneous flap pedicled with the muscle containing the terminal small branch of the descending branch of the lateral circumflex femoral artery was used in 3 cases; the medial gastrocnemius muscle flap combined with the medial half of soleus muscle flap was used in 6 cases, and the lateral gastrocnemius muscle flap combined with the anterior tibial muscle flap was used in 2 cases. After the muscle flaps had stable blood supply, the wounds were closed with thin intermediate thickness skin graft from the healthy thigh. The area of myocutaneous flap ranged from 15 cm×7 cm to 18 cm×8 cm, and the area of muscle flap ranged from 6.0 cm×4.0 cm to 18.0 cm×12.0 cm. Among the 3 patients who were treated with reverse anterolateral thigh myocutaneous flap, the wounds of flap donor site on thighs were closed by direct suturing in 2 cases, and the wound in the flap donor site of thigh in 1 case that was not closed after suture was repaired with thin intermediate thickness skin graft from healthy thigh. The incisions in the flap donor sites of 8 cases treated with calf muscle flaps were sutured directly. After surgery, the survivals of tissue flap and skin graft on the muscle flap, wound healing status and wound healing time in recipient sites of tissue flaps, suture site healing in flap donor site, and survival of skin graft were observed and recorded. Whether the steel plate was removed after operation and during follow-up was recorded. During follow-up, the shape and texture of tissue flap, whether the recipient site of tissue flap had redness, swelling, ulceration, or sinus formation were observed, the fracture healing time was recorded. At the last follow-up, the knee joint flexion and extension range of motion was measured and the knee joint function was evaluated according to Hohl's knee joint function evaluation criteria; the plantar flexor muscle strength of ankle joint was measured in 8 patients who were treated with calf muscle flaps for wound repair; the Vancouver scar scale (VSS) was used to evaluate the scar condition in the flap donor site, and whether the scar affected the movement of the affected limbs was observed. Results: Tissue flaps of 11 patients all survived after surgery. The distal end of the reverse anterolateral thigh myocutaneous flaps was necrotic in 1 patient, and the wound was healed after dressing change and grafting with thin intermediate thickness skin from healthy thigh. The distal muscle necrosis of the medial gastrocnemius muscle flap was observed in 2 patients, and the granulation tissue grew well after dressing change. The skin graft on the muscle flap survived well. All the wounds in the recipient sites of tissue flaps were healed, and the healing time was 13 to 42 days after tissue flap transplantation. The suture site of flap donor site healed, and the skin graft survived well. In 1 patient, the steel plate was removed when the wound was repaired with the medial gastrocnemius muscle flap combined with the medial half of soleus muscle flap. One patient still had exudation after 3 weeks of wound repair with the reverse anterolateral thigh myocutaneous flap pedicled with the muscle containing the terminal small branch of the descending branch of the lateral circumflex femoral artery, and the wound was healed after removing the steel plate. The steel plates of the other patients were preserved. During the follow-up of 6-25 months, except for 1 reverse anterolateral thigh myocutaneous flap had bloated pedicle, the other tissue flaps had good appearance and texture. One patient had redness and swelling in the recipient site of the tissue flap at 6 weeks after discharge, and the redness and swelling subsided without recurrence after anti-infection treatment. In 1 patient, repeated rupture and exudation occurred in the recipient site of tissue flap in 3 months after discharge, resulting in sinus tract formation, which was healed after the removing of steel plate. The fracture healing time of patients ranged from 6 to 15 months after injury. At the last follow-up, the knee joint function was evaluated as excellent in 4 cases, good in 6 cases, and poor in 1 case. Among the 8 patients who were treated with calf muscle flaps for wound repair, 7 patients had ankle joint plantar flexor muscle strength of grade Ⅵ, and 1 patient had ankle plantar flexor muscle strength of grade Ⅴ. The VSS scores of scars in the flap donor sites ranged from 2 to 7, and scars did not significantly affect the movement of the affected limbs. Conclusions: The reverse anterolateral thigh myocutaneous flap pedicled with the muscle containing the terminal small branch of the descending branch of the lateral circumflex femoral artery and the gastrocnemius muscle flap combined with soleus muscle flap or anterior tibial muscle flap are the derived types of the commonly used reverse anterolateral thigh myocutaneous flap and gastrocnemius muscle flap. Using them to repair the wounds with steel plate exposure and infection after proximal tibial fracture surgery can not only ensure the smooth operation, but also preserve the steel plate and promote fracture healing as much as possible, without significantly affecting the function of the affected limb.

[Repair methods of complex facial defect wounds involving paranasal sinuses and their clinical effectiveness].

Objective: To explore the repair methods of complex facial defect wounds involving paranasal sinuses and their clinical effectiveness. Methods: A retrospective observational study was conducted. From January 2020 to May 2022, 5 patients admitted to the Department of Burns and Plastic Surgery of Xiangya Hospital of Central South University and 4 patients admitted to the Department of Burns and Plastic Surgery of Chenzhou First People's Hospital with complex facial defect wounds involving paranasal sinuses met the inclusion criteria, including 6 males and 3 females, aged 35-69 years, including 4 patients with titanium mesh exposure combined with paranasal sinuses injury and 5 patients with tumor involving paranasal sinuses. After an adequate assessment of the damage by a multiple discipline team, titanium mesh removal, paranasal sinus debridement, and paranasal sinus mucosa removal were performed in patients with exposed titanium mesh, and radical tumor resection was performed in patients with tumors, with postoperative skin and soft tissue defects areas of 5.0 cm×2.5 cm to 18.0 cm×7.0 cm, anterior paranasal sinus wall defects/absence areas of 3 cm×2 cm to 6 cm×4 cm, and sinus cavity depths of 1 to 4 cm. Depending on the perforator course of the descending branch of the lateral circumflex femoral artery, the anterolateral femoral chimeric flap or anterolateral femoral myocutaneous flap (with flap area of 9 cm×4 cm to 19 cm×8 cm, muscle size of 5 cm×3 cm×3 cm to 11 cm×6 cm×3 cm) was transplanted to repair the defect, and the donor site wound was sutured directly. The type of tissue flap transplanted, the blood vessel of the recipient area, and the vascular anastomosis way during the operation, the recovery of the donor and recipient areas and the occurrence of complications after operation were observed. The appearance and blood supply of the recipient area and the recurrence of ulcers and tumors were followed up. Results: The anterolateral femoral myocutaneous flap transplantation was performed in 6 patients, and the anterolateral femoral chimeric flap transplantation was performed in 3 patients. The blood vessels in recipient areas were facial arteries and veins in 3 cases and superficial temporal arteries and veins in 6 cases. The superficial temporal arteries and veins were bridged with blood vessels in tissue flaps by flow-through way in 2 patients, and end-to-end anastomosis of blood vessels in donor and recipient areas was performed in 7 patients. After operation, all the tissue flaps survived, and the facial defect wounds were well repaired without cerebrospinal fluid leakage or paranasal sinus secretion leakage, no intracranial infection occurred, and the wounds in donor areas were healed well. Follow-up of 6-35 months after operation showed that all the patients had good blood supply in the recipient area, and the shape was acceptable; 4 patients with exposed titanium mesh had no recurrence of ulceration, and 5 patients with tumor had no local tumor recurrence or metastasis. Conclusions: Based on an adequate assessment of the extent of paranasal sinuses involved in the facial wound and the nature of the defect, good clinical effects can be achieved by using the anterolateral femoral muscle flap or the anterolateral femoral chimeric flap transplantation to repair complex facial defect wounds with open paranasal sinuses.

[Clinical effects of free perforator propeller myocutaneous flap from buttock in repairing complex wounds in the buttock with deep dead cavity].

Objective: To investigate the feasibility and clinical effects of using free perforator propeller myocutaneous flap from buttock in repairing complex wounds in the buttock with deep dead cavity. Methods: A retrospective observational study was conducted. From June 2020 to June 2022, 9 patients with complex wounds in the buttock with deep dead cavity who met the inclusion criteria were admitted to Lanzhou University Second Hospital, including 6 males and 3 females, aged 26 to 62 years, with original wound area ranging from 4.0 cm×3.0 cm to 8.0 cm×7.0 cm and dead cavity depth of 7 to 11 cm. All the wounds were repaired with free perforator propeller myocutaneous flap from buttock, with flap area of 6.0 cm×2.5 cm to 13.0 cm×7.0 cm and muscle flap length of 6 to 11 cm. All the wounds in the donor area were closed and sutured directly. Postoperative myocutaneous flap survival, complications, as well as donor and recipient wound healing were observed, and the shape of donor and recipient areas were followed up. Results: Congestion occurred under the myocutaneous flap of one patient due to poor drainage on post surgery day 2, which was healed after 15 days of drainage and dressing change. The myocutaneous flaps of other patients survived successfully after surgery. The wounds in the donor and recipient areas were all well healed. During the follow-up of 3 to 10 months, the donor and recipient areas were full in shape, with little difference from the healthy side, and were able to bear pressure. Conclusions: The free perforator propeller myocutaneous flap from buttock can repair the deep dead cavity and surface wounds at the same time. The use of this myocutaneous flap in repairing complex wounds in the buttock with deep dead cavity results in minimal damage to the donor area, allows pressure-bearing of the donor and recipient areas after surgery, and ensures a full buttock shape.

Vastus Lateralis and Vastus Intermedius Myocutaneous Flap Reconstruction for Complicated Trochanteric and Ischial Pressure Sores with Extended Girdlestone Resection: A Case Series.

OBJECTIVE: Most paraplegic patients with complicated trochanter sores or ischial sores present with lower limb muscle atrophy. Therefore, in patients who have undergone Girdlestone arthroplasty, filling the dead space and replacing the volume defect through an appropriate surgical technique is extremely challenging. This study presents a case series of vastus lateralis and vastus intermedius myocutaneous flap reconstruction after extended proximal femoral osteotomy in paraplegic patients. The aim of study is to investigate (i) whether sufficient volume replacement was achieved, (ii) whether muscle volume was maintained during long-term follow-up, and (iii) the presence of donor site morbidity. METHOD: A retrospective review was conducted with eight patients who underwent this method from March 2017 to December 2021. A total of nine flaps was elevated, and the defect was successfully reconstructed without dead space. Computed tomography was performed to identify the changes in thickness and volume of the muscle portion. The Wilcoxon signed-rank test was performed to assess the significance of the differences in muscle thickness between pre- and post-measurements. RESULTS: After surgery, all patients healed within 1 month; three patients experienced minor complications. The average follow-up period was 14.5 months, during which only one patient with an ischial pressure ulcer developed wound disruption and recurrence. The average thickness of the rotated muscle was 51.95 mm at 2 to 4 weeks postoperatively and 53.07 mm at 6 months postoperatively (𝑝 = 0.071). CONCLUSION: All nine cases healed well without major complications. When comparing the volume of the rotated muscle on radiological examinations before and after surgery, no significant differences were observed. Our modified Girdlestone resection technique provides a simple and reliable method for reconstructing complex trochanteric or ischial sores in paraplegic patients. It ensures anatomical consistency, ample volume, and structural stability by leaving the rectus femoris (RF) in place. Careful tension management is required when using this flap in the ischial area.

Breast reconstruction for locally advanced breast cancer previously submitted to mastectomy and an ipsilateral thoracoabdominal dermofat (ITADE) flap.

Thoracoabdominal (TA) flaps are a good option for primary closure of small and medium defects after mastectomy for locally advanced breast tumours. Although they have a higher rate of necrosis than myocutaneous flaps, they can be easily performed by breast surgeons. Few studies on this procedure have been reported, and we have been unable to identify any prior publications reporting breast reconstruction with TA flaps.

Do Socioeconomic Status and Race Impact the Safety and Efficacy of Breast Reconstruction?

INTRODUCTION: Immediate breast reconstruction after mastectomy has increased in recent years when compared with delayed reconstruction. Despite this encouraging trend, racial and socioeconomic disparities in the receipt of postmastectomy breast reconstruction have been well documented. We sought to assess the effect of race, socioeconomic status, and patient comorbidities on muscle sparing transverse rectus abdominis myocutaneous outcomes at our safety net hospital institution in the southeast. METHODS: The database of a tertiary referral center was queried for patients who received free transverse rectus abdominis myocutaneous flaps for immediate reconstruction after mastectomy meeting inclusion criteria from 2006 to 2020. Patient demographics and outcomes were compared based on socioeconomic status. The primary outcome (reconstructive success) was defined as breast reconstruction without flap loss. Statistical analysis included analysis of variance and χ2 tests were appropriate using Rstudio. RESULTS: Three-hundred fourteen patients were included in the study, with 76% White, 16% Black, and 8% other. Overall complication rate at our institution was 17% and reconstructive success was 94%. Non-White race, older age at time of breast cancer diagnosis, higher body mass index, and presence of comorbid conditions including current smoking and hypertension were all associated with low socioeconomic status. Despite this, surgical complication rates were not predicted by non-White race, older age, or presence of diabetes mellitus. When analyzing major and minor complications based on radiation received or reconstructive success, there was no significant difference regardless of radiation treatment with the group overall achieving a 94% success rate (P = 0.229). CONCLUSIONS: This study aimed to characterize the impact of socioeconomic status and race/ethnic status of patients on breast reconstruction outcomes at an institution in the South. We found that despite the greater morbidity in low income and ethnic/minority patients that when treated by a comprehensive safety net institution, they had excellent reconstructive outcomes due to low complications and minimal reoperations.

Autologous myocutaneous flap implantation for chronic refractory chest wall sinus with infection: a case report.

BACKGROUND: Chest wall sinus with infection is a refractory disease caused by a variety of susceptible factors, and the treatment is still challenging. For clinically complex cases, although there are various surgical methods to choose from, it is still very difficult to achieve clinical cure, especially for patients with older age and many underlying diseases. Complete resection of chest wall sinus and application of repair and reconstruction technology may bring hope to refractory cases. CASE PRESENTATION: Herein, we report a case of a 67 year-old woman who had undergone breast cancer surgery and a history of multiple cycles of radiotherapy and chemotherapy. One year ago, she had a fistula in the left chest wall with yellow purulent fluid. After admission to our hospital, chest computed tomography (CT) showed the formation of the left chest wall sinus, accompanied by high-density images of the left clavicle, part of the ribs and part of the sternu. According to the patient's symptoms, signs and imaging examination, we preliminarily diagnosed the patient as chest wall sinus with infection and chronic osteomyelitis. Therefore, in the first-stage operation, the patient underwent left chest wall sinus resection, left partial rib resection, left partial clavicular resection and left partial sternal resection, After surgery, the wound surface was changed with gauze dressing with sensitive antibiotic solution every day until the wound surface was clean and new granulation was formed. In the second-stage operation, the wound surface was appropriately expanded, and the pedicled latissimus dorsi myocutaneous flap was transferred to the chest wall defect. Finally, the skin paddle was sutured without tension to the normal skin around the chest, and two drainage tubes were placed. Anti-infection, anti-spasm, anti-coagulation and other treatments were given after operation, and the survival of myocutaneous flap, wound healing and sinus disappearance were observed. CONCLUSION: The application of pedicled latissimus dorsi myocutaneous flap in the treatment of intractable chronic chest wall sinus is an effective method. It does not change the shape of the thorax. The clinical effect is satisfactory in the near and medium term, which is worthy of clinical promotion.

[Effectiveness of lobulated pedicled rectus abdominis myocutaneous flap for repairing huge chest wall defect].

Objective: To explore the effectiveness of lobulated pedicled rectus abdominis myocutaneous flap to repair huge chest wall defect. Methods: Between June 2021 and June 2022, 14 patients with huge chest wall defects were treated with radical resection of the lesion and lobulated pedicled rectus abdominis myocutaneous flap transplantation for reconstruction of chest wall defects. The patients included 5 males and 9 females with an average age of 44.2 years (range, 32-57 years). The size of skin and soft tissue defect ranged from 20 cm×16 cm to 22 cm×22 cm. The bilateral pedicled rectus abdominis myocutaneous flaps in size of 26 cm×8 cm to 35 cm×14 cm were prepaired and cut into two skin paddles with basically equal area according to the actual defect size of the chest wall. After the lobulated pedicled rectus abdominis myocutaneous flap was transferred to the defect, there were two reshaping methods. The first method was that the skin paddle at the lower position and opposite side was unchanged, and the skin paddle at the effected side was rotated by 90° (7 cases). The second method was that the two skin paddles were rotated 90° respectively (7 cases). The donor site was sutured directly. Results: All 14 flaps survived successfully and the wound healed by first intention. The incisions at donor site healed by first intention. All patients were followed up 6-12 months (mean, 8.7 months). The appearance and texture of the flaps were satisfactory. Only linear scar was left at the donor site, and the appearance and activity of the abdominal wall were not affected. No local recurrence was found in all tumor patients, and distant metastasis occurred in 2 breast cancer patients (1 liver metastasis and 1 lung metastasis). Conclusion: The lobulated pedicled rectus abdominis myocutaneous flap in repair of huge chest wall defect can ensure the safety of blood supply of the flap to the greatest extent, ensure the effective and full use of the flap tissue, and reduce postoperative complications.

[Combination mode and optimization strategy of harvest procedure of anterolateral thigh chimeric perforator myocutaneous flap].

Objective: To summarize the combination methods and optimization strategies of the harvest procedure of anterolateral thigh chimeric perforator myocutaneous flap. Methods: A clinical data of 359 cases of oral cancer admitted between June 2015 and December 2021 was retrospectively analyzed. There were 338 males and 21 females with an average age of 35.7 years (range, 28-59 years). There were 161 cases of tongue cancer, 132 cases of gingival cancer, and 66 cases of buccal and oral cancer. According to the Union International Center of Cancer (UICC) TNM staging, there were 137 cases of T 4N 0M 0, 166 cases of T 4N 1M 0, 43 cases of T 3N 1M 0, 13 cases of T 3N 2M 0. The disease duration was 1-12 months (mean, 6.3 months). The soft tissue defects in size of 5.0 cm×4.0 cm to 10.0 cm×7.5 cm remained after radical resection were repaired with the free anterolateral thigh chimeric perforator myocutaneous flaps. The process of harvesting the myocutaneous flap was mainly divided into 4 steps. Step 1: exposing and separating the perforator vessels, which mainly came from the oblique branch and the lateral branch of the descending branch. Step 2: isolating the main trunk of the perforator vessel pedicle and determining the origin of the vascular pedicle of muscle flap, which was came from oblique branch, lateral branch of the descending branch, or medial branch of the descending branch. Step 3: determining the source of muscle flap, including lateral thigh muscle and rectus femoris muscle. Step 4: determining the harvest form of muscle flap, which included muscle branch type, main trunk distal type, and main trunk lateral type. Results: The 359 free anterolateral thigh chimeric perforator myocutaneous flaps were harvested. In all cases, the anterolateral femoral perforator vessels existed. The perforator vascular pedicle of the flap came from the oblique branch in 127 cases and the lateral branch of the descending branch in 232 cases. The vascular pedicle of muscle flap originated from the oblique branch in 94 cases, the lateral branch of the descending branch in 187 cases, and the medial branch of the descending branch in 78 cases. The muscle flaps harvested from the lateral thigh muscle in 308 cases and the rectus femoris muscle in 51 cases. The harvest forms of muscle flaps included 154 cases of muscle branch type, 78 cases of main trunk distal type, and 127 cases of main trunk lateral type. The size of skin flaps ranged from 6.0 cm×4.0 cm to 16.0 cm×8.0 cm, and the size of muscle flaps range from 5.0 cm×4.0 cm to 9.0 cm×6.0 cm. In 316 cases, the perforating artery anastomosed with the superior thyroid artery, and the accompanying vein anastomosed with the superior thyroid vein. In 43 cases, the perforating artery anastomosed with the facial artery, and the accompanying vein anastomosed with the facial vein. After operation, the hematoma occurred in 6 cases and vascular crisis in 4 cases. Among them, 7 cases were successfully saved after emergency exploration, 1 case had partial necrosis of skin flap, which was healed after conservative dressing change, and 2 cases had complete necrosis of skin flap, which was repaired by pectoralis major myocutaneous flap. All patients were followed up 10-56 months (mean, 22.5 months). The appearance of the flap was satisfactory, and the swallowing and language functions were restored satisfactorily. Only linear scar left in the donor site with no significant effect on thigh function. During follow-up, 23 patients had local tumor recurrence and 16 patients had cervical lymph node metastasis. The 3-year survival rate was 38.2% (137/359). Conclusion: The flexible and clear classification of the key points in the harvest process of anterolateral thigh chimeric perforator myocutaneous flap can optimize the protocol to the greatest extent, increase the safety of the operation, and reduce the difficulty of the operation.

Modern Approaches to Alternative Flap-Based Breast Reconstruction: Transverse Upper Gracilis Flap.

The transverse upper/myocutaneous gracilis is a medial thigh-based flap primarily reserved as a secondary choice for autologous reconstruction of small to moderate-sized breasts in women without a suitable abdominal donor site. Its consistent and reliable anatomy based on the medial circumflex femoral artery permits expedient flap harvest with relatively low donor site morbidity. The primary disadvantage is the limited achievable volume, often necessitating augmentation such as extended flap modifications, autologous fat grafting, flap stacking, or even implant placement.

Head and Neck Reconstruction With 2-Stage External Pectoralis Major Myocutaneous Flap Transfer.

BACKGROUND: In head and neck surgery cases where skin is severely scarred or adhered to surrounding tissue, reconstruction can be difficult to perform using microsurgical tissue or conventional pedicled pectoralis major myocutaneous flap (PMMF) transfer given the risks, which include damage to major vessels when manipulating scarred skin. For such cases, we perform a 2-stage external PMMF transfer, whereby the PMMF is directly sutured to the defect over the neck skin (without manipulation the hardened skin), and the flap division is then performed secondarily. METHODS: A total of 30 patients who had histories of radiotherapy (60-70 Gy) and prior neck dissection received the 2-stage external PMMF transfer procedure. Indications for the flaps included pharyngeal fistula closure in 12 patients, reconstruction for mandibular necrosis after radiotherapy in 8 patients, salvage surgery for partial or total necrosis of the free flap in 4 patients, and simultaneous reconstruction after tumor excision in 6 patients. Two patients underwent a second external PMMF transfer from the contralateral side because of postoperative complications, yielding a total of 32 flap transfers. RESULTS: Twenty-nine flaps showed complete flap survival, whereas 3 had partial necrosis. Other complications, despite complete flap survival, included large fistulas requiring additional surgery for fistula closure (1 patient) and small fistulas that were closed without requiring reoperation (7 patients). CONCLUSIONS: External PMMF transfer offers a safe, simple, and effective option in cases where free flap surgery is considered difficult or the risks associated with neck manipulation are high.

[Anatomical types and anastomosis methods of concomitant veins of deep inferior epigastric artery].

Objective: To summarize the anatomical types of the concomitant veins of deep inferior epigastric artery and the corresponding choice of anastomosis methods, and to evaluate the indications and safety of various methods. Methods: Between October 2015 and June 2021, 296 female patients received breast reconstruction with autologous free lower abdominal flap, including 154 cases of immediate breast reconstruction and 142 cases of delayed breast reconstruction. The average age of the patients was 36.5 years, ranged from 26 to 62 years. Unilateral free deep inferior epigastric artery perforator flap transplantation was performed in 172 cases, and unilateral free muscle-sparing rectus abdominis myocutaneous flap transplantation was performed in 124 cases. The internal thoracic vessels were selected as the recipient vessels in all cases. The length of vascular pedicle ranged from 9.5 to 13.0 cm, with an average of 11.2 cm. The concomitant veins of deep inferior epigastric artery included three anatomical types: one-branch type in 26 cases (8.8%), two-branch type in 180 cases (60.8%), and Y-shaped structure in 90 cases (30.4%). Anastomosis of inferior epigastric artery was performed with the proximal end of internal thoracic artery, while that of vein should be adjusted according to the diameter, length, wall thickness, and branches of the vein. The specific classification of venous anastomosis included: ① The sole concomitant vein of deep inferior epigastric artery was anastomosed with the internal mammary vein (26 cases); ② The two concomitant veins of deep inferior epigastric artery were anastomosed with the internal mammary vein respectively (151 cases); ③ The larger one of two concomitant veins of deep inferior epigastric artery was anastomosed with the internal mammary vein, and the other one was ligated and discarded (29 cases); ④ The two concomitant veins of deep inferior epigastric artery were Y-shaped, and the common trunk segment was directly anastomosed with the internal mammary vein (31 cases); ⑤ The smaller branch of the concomitant veins of Y-shaped structure was ligated, and the thicker branch was anastomosed with the internal mammary vein (17 cases); ⑥ The concomitant veins of Y-shaped structure were anastomosed with the internal mammary veins respectively (42 cases). Results: Among the patients who underwent venous anastomosis according to scheme ④, 3 cases had venous crisis of flap after operation, of which 1 case was successfully rescued by emergency exploration; the other 2 cases had flap necrosis, of which 1 case survived after being repaired by pedicled latissimus dorsi flap, and 1 case closed the wound directly. Flaps with other venous anastomosis protocols survived completely. All 296 patients were followed up 12-70 months, with an average of 37.5 months. The reconstructed breast has good shape, good elasticity, and no skin flap contracture. The donor site of the flap only left linear scar, and the abdominal wall function was not affected. Conclusion: The method of direct anastomosis of concomitant veins of deep inferior epigastric artery with Y-shaped structure is relatively risky, and the vessels are prone to be twisted and compressed, leading to the occurrence of venous crisis. It can improve the safety of surgery if only one large vein is anastomosed or two veins are separated to anastomose respectively.
