Viability of the rectus femoris muscle flap for groin wound coverage after ligation of proximal inflow.

Lower extremity revascularization via groin incisions can be complicated by wound dehiscence associated with infection, seroma and femoral vessel exposure. This may require additional surgical debridement and coverage of vascular structures and grafts. The pedicled rectus femoris muscle flap (RFF) has both bulk and a large arc of rotation, making it useful for reconstruction. Its main pedicle is the descending branch of the lateral femoral circumflex artery (DLFCA), a branch of the profunda femoris artery. One could anticipate that ligation of more proximal vasculature could lead to ischemia of the RFF. We present two patients who each underwent vascular surgery involving the common femoral artery and subsequent reconstruction utilizing a pedicled RFF. Both patients then required additional vascular procedures involving the ligation of inflow vessels proximal to the DLFCA. The flaps remained viable, demonstrating the rich collateralization of blood supply that occurs in vascular disease patients.

From Risk Assessment to Intervention: A Systematic Review of Thrombosis in Plastic Surgery.

Thromboembolism is a feared complication in plastic surgery and is linked to higher rates of morbidity and mortality. Despite extensive research, there is a lack of consistency between recommendations and clinical protocols to be implemented pre and post-surgery to reduce the incidence of thromboembolism. A systematic literature review was conducted using Pubmed and Scopus databases to determine the risk factors, screening methods, and existing treatment models for thromboembolism prevention. Articles in non-English languages were excluded. Analysis indicated that predominant risk factors include age (>35), elevated body mass index, coagulation disorders, smoking, estrogen therapies, genetic predisposition, vascular endothelium damage, stasis, and use of general anesthesia in patients with a history of cancer. Implementation of a proper prophylactic protocol is dependent on understanding the interplay between the aforementioned risk factors and the utilization of well-defined, evidence-based guidelines, such as the 2005 Caprini Risk Assessment Model and ultrasound surveillance. The literature review revealed that mechanical prophylaxis is the primary prevention method, followed by thromboprophylaxis for patients with higher Caprini scores. Plastic surgeons often underestimate the present risk stratification tools available for the prophylactic intervention of thromboembolism due to the fear of bleeding or hematoma complications postoperatively. In summary, this literature review emphasizes the importance of plastic surgeons selecting protocols that is inclusive of the patient's risk profile to yield a reduced risk of thromboembolism.

Tweeting for Success: The Role of Twitter in Enhancing SCImago Journal Rank for Specialty Surgical Journals.

Background The cornerstone of surgical education and practice is the surgical journal, but the ability to disperse the vital information within their pages had previously been limited. The use of Twitter by surgical journals has increased in recent years and has allowed these journals to reach a wider audience than they previously could. In this article, we discuss the role Twitter engagement has on a journal's impact factor, visibility, and prestige. Methods The authors compiled a list of journals using the SciMago Journal and Country rank platform. Included journals' Twitter profiles were then assessed using Twitonomy, an online platform that collects and processes data regarding individual Twitter profiles. Statistical analysis was conducted to determine the relationship between Twitter use and SCImago Journal Rank (SJR). Results Simple linear regression and multiple linear regression models determined that the only variables that had a statistically significant impact on all journals were the age of the Twitter account (p=0.003) and the percentage of retweets (p=0.001). When it comes to specialty-specific journals, further analysis showed that the only significant factor regarding its impact on SJR was the percentage of retweets (p=0.007). Conclusions Surgical journals' regular use of Twitter is important in the dissemination of important information to a wide audience. This article shows that the most important variable to determine the impact and visibility of a surgical journal is the percentage of retweets. Further research should be performed to better understand how to use Twitter and other social media platforms to reach a larger audience.

Use of Negative-Pressure Wound Therapy With Instillation and Dwell Time: An Overview.

SUMMARY: The use of negative-pressure wound therapy (NPWT) has become an established therapy for wound management. There have been many advancements in the technology of NPWT including NPWT with instillation and dwell (NPWTi-d). NPWTi-d promotes wound healing by wound cleansing, irrigation, and nonexcisional debridement. NPWTi-d has been shown in comparative clinical studies to decrease the time to definitive wound healing and length of hospitalization. NPWTi-d-using a reticulated open-cell foam dressing with "through" holes (ROCF-CC)-has been postulated to facilitate solubilization, detachment, and elimination of infectious materials, such as slough and thick exudate, before or after operative debridement, and in cases where surgical debridement is not an option. The authors provide an overview on the use of NPWTi-d by reviewing the components of the system, proposed mechanism of action, clinical outcomes, and current consensus guidelines for its utilization.

Exophytic Adiposis Dolorosa (Dercum's Disease) of the Thigh: A Case Report.

Adiposis dolorosa or Dercum's disease is a rare lipomatous disorder characterized by painful lipomas. In this article, we report a case of rather large exophytic adiposis dolorosa causing difficulties with ambulation, and our surgical management of the disorder. To our knowledge, this is the first reported case of a large exophytic adiposis dolorosa of the upper medial thigh causing problems with mobility. This is also the first reported case of the use of a delayed split-thickness skin graft (STSG) after interval use of wound vacuum-assisted closure (VAC) following dermolipectomy. A 77-year-old female presented with a chronic mass on the medial aspect of her right thigh for over 40-50 years. She had noticed a recent rapid increase in size, causing some discomfort and interference with mobility and activities of daily living. The patient underwent an MRI with finding consistent with adiposis dolorosa. She underwent dermolipectomy and reconstruction of the resulting defect with a combination of partial primary closure, wound VAC, and delayed closure using STSG. Dermolipectomy with interval application of a wound VAC combined with delayed reconstruction with STSG is a feasible option for patients with large lesions of the extremity that causes difficulty with mobility and activities of daily living.

Revisiting the musculocutaneous external oblique flap as a versatile alternative in large thoracic wall defects.

BACKGROUND: The external oblique myocutaneous flap has been previously described for reconstruction of chest-thoracic wall defects smaller than 400-500 cm2. However, it is utilized less often than workhorse flaps such as the omental, pectoralis, rectus abdominis, and latissimus dorsi myocutaneous flaps as many plastic surgeons are not aware that the flap can cover larger areas than previously documented. CASE PRESENTATION: We report a 57-year-old female tobacco user who underwent a resection of a grade 3 breast angiosarcoma resulting in a high left chest wall soft tissue defect approximating 900 cm2. The patient underwent an external oblique myocutaneous pedicle flap reconstruction of the defect, most notably in anticipation of postoperative adjuvant radiation therapy. No gross flap complications and or patient impairment were noted. Thirteen months status post flap reconstruction, the patient underwent an aortic valve replacement requiring re-elevation of the same flap for exposure. The flap demonstrated excellent viability during the procedure and postoperatively. CONCLUSION: The pedicled external oblique myocutaneous flap should be considered when reconstructing larger high chest wall defects when other more common flaps used in chest reconstruction may not be indicated. The external oblique myocutaneous flap is an excellent tool in the armamentarium of any reconstructive surgeon; it is a straightforward and versatile flap that can be safely and reliably used in durable reconstruction of defects of the chest wall and covers defects larger than previously described in the literature.

Reconstruction of sternoclavicular defect with completely detached pectoralis major flap.

Sternoclavicular joint infection is very rare. Osteomyelitis is a known complication of septic sternoclavicular joint. Once this condition is diagnosed, aggressive management including antibiotic and surgical debridement is warranted. Patients are often left with sizeable sternoclavicular defects that may need surgical reconstruction. In this report, we describe the use of a completely detached pectoralis major flap for the reconstruction of a large sternoclavicular defect after resection for osteomyelitis. Briefly, after the debridement of the infected sternoclavicular joint, the pectoralis major was detached from its sternoclavicular attachments and further detached from the humeral attachments rendering it completely detached on a vascular pedicle. The muscle was advanced to cover the defect and secured. Patient recovered well without any surgery related complication. She retained good use of the ipsilateral upper extremity. The pectoralis major can be completely detached to provide ample coverage for sternoclavicular joint reconstruction if needed.

A Case Review of Wound Bed Preparation in an Infected Venous Leg Ulcer Utilizing Novel Reticulated Open Cell Foam Dressing with Through Holes during Negative Pressure Wound Therapy with Instillation.

Chronic venous insufficiency (CVI) and venous leg ulcers (VLUs) have major financial implications for patients and healthcare professionals. VLUs, in particular, require significant care, can be slow to heal, and have a high rate of recurrence. These factors combine to make VLUs a major burden on the healthcare system. Recent estimates show that the cost of treatment of VLUs per patient in the United States is $10,000 to $12,000 per year, with the average lifetime cost of care greater than $40,000. Infected VLUs often require surgical debridement for the removal of bacterial burden and biofilm. The use of negative pressure wound therapy with instillation and dwell (NPWTi-d) has shown to decrease OR visits, length of hospitalization, and therapy days in lower extremity and trunk wounds. In 2017, a novel reticulated open cell foam dressing with through holes (ROCF-CC) was introduced as a dressing option with NPWTi-d. ROCF-CC assists in removing thick wound exudate and infectious materials. This dressing option is especially helpful for wound cleansing when debridement is not possible or appropriate in patients.

The pedicled latissimus dorsi flap for shoulder reconstruction after sarcoma resection.

BACKGROUND: Tumor extirpation around the shoulder can result in large defects requiring coverage of allograft-alloprosthetic constructs and vital neurovascular structures. This study examined a single institution's experience with the pedicled latissimus dorsi flap in reconstructing large shoulder defects after oncologic resection. METHODS: Using a prospectively maintained database, 33 consecutive patients were reviewed who had undergone a pedicled latissimus dorsi flap to reconstruct oncologic shoulder defects between 1994 and 2004. Wide excision or radical en-bloc resection of shoulder tissues was performed with defects often extending intra-articularly and to the level of the mid-arm. Patient demographics, comorbid conditions, pathology, adjuvant treatment, defect characteristics, skin paddle dimensions and operative records were evaluated. Outcome variables included major and minor complications, patient survival, and limb viability. RESULTS: Adjuvant therapy included chemotherapy in 18 patients, radiation therapy in 12 patients, and brachytherapy in 2 patients. Defects averaged 280.1 cm2 (range 18-1,225 cm2). Mean skin paddle surface area was 118.9 cm2 (range 21-350 cm2). There were 28 myocutaneous flaps and 5 muscle flaps. Materials for bony reconstruction included 13 allograft and alloprosthetic composites, 6 metallic prostheses, and 3 reconstructions using allograft alone. Two patients experienced partial skin flap necrosis. One patient developed local recurrence. Two patients required combined flaps. CONCLUSIONS: Use of the pedicled latissimus dorsi flap in complex shoulder reconstructions provided ample well-vascularized soft tissue, minimized risk of infection, and maximized limb salvage. In our experience, the pedicled latissimus dorsi flap is an excellent choice for reconstruction of defects around the shoulder after tumor extirpation.

Free tissue transfer: comparison of outcomes between university hospitals and community hospitals.

BACKGROUND: In university hospitals, free tissue transfer has become a standard method of reconstruction for a broad spectrum of defects. Because of its complexity, free tissue transfer has not been routinely performed in a community hospital setting. This study reports the outcomes of two equal groups of free tissue transfer performed by the same surgeons, comparing the university versus the community hospital setting. METHODS: A total of 735 free tissue transfers were performed at one university hospital and six community hospitals in our region over a 10-year study period. Outcome parameters used in this study included wound complications such as infection, dehiscence, delayed healing, hematoma, and fat necrosis. RESULTS: A total of 674 operations were performed using 735 free tissue transfers: 386 free tissue transfers were performed at the university hospital (53 percent) and 349 (47 percent) were performed at the community hospital. Categories of free tissue transfer reconstruction included breast, lower extremity, head and neck, and upper extremity reconstructions. Most of the breast reconstructions were performed in the community hospital, whereas most of the lower extremity and head and neck reconstructions were performed at the university hospital. Fifty-one major postoperative complications occurred in the university hospital (14 percent), while 31 (10 percent) occurred in the community hospital. Complication rates did not differ significantly between settings; however, there was a trend toward more wound infections in the university hospital and more cases of fat necrosis in the community hospital, most likely reflected in the differing case mix between hospital settings. CONCLUSION: Free tissue transfer is an effective and practical method of reconstruction that has been safely performed in both university and community hospital settings.

TRAM flap breast reconstruction for patients with advanced breast disease.

Transverse rectus abdominis musculocutaneous (TRAM) breast reconstruction in patients with advanced breast cancer is controversial. Management of these patients is often complex and consists of surgical extirpation, postoperative radiation, chemotherapy, and in some cases bone marrow transplantation. Few studies have attempted to examine patient long-term survival and overall satisfaction with the surgical procedure. This study examines one center's experience with patients undergoing breast reconstruction for stage III and stage IV breast carcinoma. A retrospective review was performed of all patients undergoing TRAM reconstruction with stage III or IV breast cancer. Surviving patients and family members were contacted for follow-up. Patients were asked to grade their satisfaction with the reconstructive procedure on a 5-point scale (5 points, extremely satisfied; 1 point, extremely dissatisfied). Postoperative complications and time to return to work were also recorded. During a 10-year period (1991-2000) 21 women underwent TRAM reconstruction for advanced breast cancer. Twenty patients had stage III disease and 1 patient had stage IV disease. Mean patient age was 49 years. A total of 26 TRAM flaps were performed; 5 patients had bilateral procedures. Of the 26 TRAM flaps, 17 were immediate and 9 were delayed, and 20 were free and 6 were pedicled. Follow-up averaged 6.5 years (range, 2-10 years). Postoperative complications occurred in 7 patients and included fat necrosis (N = 3), hematoma (N = 2), cellulitis (N = 1), delayed donor site healing (N = 2), and seroma (N = 1). There were no flap losses. Patients were able to return to normal activities or work at an average of 10.6 weeks. Eleven patients developed recurrent disease. Nine patients (43%) succumbed to their disease during the follow-up period. In these patients the average interval between TRAM reconstruction and death was 3.7 years (range, 1-6.5 years). Eleven patients or surviving family members participated in the patient satisfaction survey. The average satisfaction grade was 4.6 points. All patients would repeat the TRAM reconstruction again. Patients with advanced breast cancer can be considered appropriate candidates for TRAM reconstruction. The results of this study indicate that patients with advanced breast cancer do not have an increased rate of postoperative complications, and they recover within a reasonable time from their surgical procedure despite adjuvant radiation and chemotherapy. Furthermore, the majority of patients are satisfied with their reconstructed breast and postoperative course, and would choose this reconstructive option again.

An outcome analysis comparing the thoracodorsal and internal mammary vessels as recipient sites for microvascular breast reconstruction: a prospective study of 100 patients.

The thoracodorsal vessels have been the standard recipient vessels for the majority of surgeons performing free transverse rectus abdominis musculocutaneous (TRAM) flap reconstructions. Recently, the internal mammary vessels have been recommended as the first-choice recipient vessels for microvascular breast reconstruction. This approach requires a shorter pedicle length, allows for central placement of flap tissue, and avoids axillary scarring. The use of the internal mammary vessels may provide for a shorter operative time and a higher-quality aesthetic reconstruction. The authors performed a prospective trial examining the differences in operative and aesthetic outcomes between each recipient site. A prospective trial of 108 consecutive free-tissue transfers was conducted in 100 patients. The first 60 TRAM flap patients were randomized so that 30 flaps were anastomosed to the internal mammary vessels and 30 were anastomosed to the thoracodorsal vessels, whereas the recipient vessels for the remaining 40 patients were left to the discretion of the surgeon. Of the 40 nonrandomized patients, 10 patients underwent reconstruction using the internal mammary vessels and 30 patients underwent reconstruction using the thoracodorsal vessels. The patients' medical history and hospital course were noted. To evaluate aesthetic outcome, a group of five blinded nonmedical observers and three blinded plastic surgeons graded the reconstructions in the 60 TRAM flap patients for symmetry and overall aesthetic result on a scale of 1 to 5. Blinded practitioners administered postoperative questionnaires to patients regarding recovery time and satisfaction with the aesthetic result. Forty-three flaps were transferred to the internal mammary vessels and 65 were transferred to the thoracodorsal vessels. No significant differences existed between groups with regard to age of preoperative risk factors. Average operative time was 6 hours in each group. Average hospital stay was 5.8 days in each group. Conversion from initial recipient vessel to a secondary recipient site occurred in 12.5 percent of internal mammary reconstructions and 7 percent of thoracodorsal reconstructions. All converted internal mammary cases occurred in left-sided reconstructions and were attributable to problems with the veins. Overall, 20 percent of left-sided internal mammary reconstructions were found to have an inadequate recipient vein. Unusable thoracodorsal vessels were found only in delayed reconstructions, at a rate of 15 percent in the delayed setting. All flaps from converted procedures survived without complications. Average follow-up was 20 months, during which time there was one flap loss in the thoracodorsal group. There were no significant differences in complication rates between groups. Average aesthetic grade was 3.6 in each group. Postoperative recovery time and overall patient satisfaction were not significantly different between groups. Either recipient site can provide for a safe and acceptable result; however, surgeons should be aware of conversion rates and plan appropriately if recipient vessels appear unusable for free-tissue transfer.

Effects of late loss of arterial inflow on free flap survival.

Greater than 80 percent of free flap thromboses have been shown to occur within the first three postoperative days, warranting immediate re-exploration and restoration of adequate vessel patency. The infrequency of thromboses beyond this period is reflected in the lack of reported cases in the literature and the absence of accepted guidelines for the treatment of such delayed complications. A single study reported free flap survival in vessel thromboses only when encountered after postoperative day (POD) 7 in a pig model. Since 1990, over 800 free tissue transfers have been done at the University of Rochester. A total of ten cases of late (defined as after POD 7) arterial inflow loss were identified and examined. A retrospective chart review recorded patient demographics, site of tissue defect, free tissue transferred, major co-morbidities, preoperative XRT, timing of arterial inflow loss, nature of inflow loss, and flap survival. The mean POD of arterial inflow loss was 53 days (range: 8 to 166). The mean age of patients was 58 years. No major co-morbidities correlated with late arterial inflow loss. Loss of inflow occurred as anastomotic rupture (5), occlusion of recipient bypass graft in lower extremity cases (3), primary donor arterial thrombosis (1), and pedicle avulsion during re-exploration for seroma (1). Five flaps survived, one sustained partial necrosis, and four were completely lost. Of the five surviving flaps, three were inset into healthy recipient sites. One was utilized on a dysvascular lower extremity, and another was used in an irradiated neck defect. Of the four failed flaps, all were placed in recipient beds compromised by radiation, ischemia, or scarring. Two exemplary case reports are presented. The timing of late loss of arterial inflow does not appear to be the primary determinant of free tissue survival. The condition and quality of the recipient site plays a large role in survival of these flaps. Ischemic, irradiated, and scarred beds are inadequate in providing late flap neovascularization, compared to healthy recipient sites. When encountering late loss of arterial inflow in flaps placed on such compromised beds, the microsurgeon should not anticipate survival based on surrounding vessel ingrowth. More aggressive salvage attempts may be warranted.
