RESUMO

BACKGROUND: The safety and outcome of breast reconstruction after radiotherapy are controversial, and the aesthetic aspects have not been studied extensively. We compared the results of vascular anastomosis, the incidence of postoperative complications, and aesthetic appearance between patients who had and had not received radiotherapy who then had undergone delayed breast reconstruction with autologous free flaps from the abdomen, thighs, and buttocks. METHODS: In total, 257 flaps in 241 patients were investigated; 194 and 63 flaps implanted in patients who did not receive radiotherapy and who received radiotherapy before breast reconstruction, respectively. Of the 257 flaps, 221, 20, 14, and 2 came from the abdomen, thighs, buttocks, and other anatomic locations, respectively. We evaluated aesthetic outcomes in 105 patients who had not received radiotherapy and 35 who had. RESULTS: We found no significant differences between the two groups in the incidence of vascular reanastomosis, the time required for anastomosis, or the incidence of unplanned reoperation. Complications such as flap necrosis were rare in both groups. Aesthetic outcomes were significantly better in the patients who had not received radiotherapy. CONCLUSIONS: Breast reconstruction with autologous free flaps can be performed safely in patients who have received radiotherapy, but the aesthetic result is slightly inferior to that in patients who had not received radiotherapy.

RESUMO

Various cytochrome P450 enzymes (CYPs) that contribute to drug metabolism are expressed in the skin. However, variation among individuals in CYP expression profiles is not well-understood.To investigate CYPs related to the metabolism of transdermal preparations in Japan, multiple skin tissue specimens of individuals of Japanese descent were prepared, and the mRNA expression levels of CYP1A2, CYP3A4, and CYP3A5 were measured. Associations between the expression patterns of these CYPs and body mass index (BMI) were also investigated.There were considerable individual differences in epidermal CYP1A2 mRNA expression levels, and CYP1A2 showed a weak positive correlation with CYP3A4 mRNA expression levels. In contrast to previous results for other organs, epidermal CYP3A4 mRNA expression levels showed a weak positive correlation with BMI.CYP3A4 in the epidermis may have been locally enhanced as a defence mechanism against xenobiotics in response to impaired barrier function. These differences in mRNA expression in the skin may affect the transdermal absorption of drugs, such as lidocaine and fentanyl, which are metabolised by multiple overlapping CYPs.Our study provides new insights into drug metabolism in the skin. These results are valuable for predicting drug effects and transdermal drug transfer rates in Japanese patients.

RESUMO

BACKGROUND: Although endoscopic mastectomy has been associated with good tolerance and enhanced patient satisfaction, limitations such as the implant or flap size for reconstruction with small incisions remain unresolved. Fat grafting (FG) can expand tissue volume with pinhole skin incisions. Herein, we evaluated the safety and efficacy of endoscopic mastectomy followed by immediate FG. METHODS: Patients who underwent endoscopic mastectomy with immediate FG reconstruction from 2015 to 2021 were retrospectively evaluated to establish surgical outcomes and prognosis. RESULTS: Twenty-three patients with clinical stage 0 or I breast cancer underwent unilateral endoscopic mastectomy with immediate FG. The median age was 45 years (41-55), and the median body mass index was 19.3 kg/m2 (15.8-26.6). Endoscopically performed procedures included skin-sparing mastectomies in 18 patients (78%) and nipple-sparing mastectomies in five patients (22%). The median procedure duration was 295 min (242-346). The median specimen weight was 133 g (71-334), and the median grafted fat volume was 200 mL (136-320). No patient required reoperation or additional procedures for complications. One patient experienced recurrence at a median follow-up of 56.1 months and underwent resection; the patient was alive without recurrence 54 months post-resection. CONCLUSION: To the best of our knowledge, this is the first report of endoscopic mastectomy with immediate FG for reconstruction. When compared with other immediate autologous reconstructions, our strategy could minimize the skin incision and procedure duration, as well as limit complications. Further prospective investigations are needed to evaluate oncological safety, surgical outcomes, and patient satisfaction.

RESUMO

On the basis of our numerous years of experience in teaching residents without microsurgery experience and assisting in the initiation of microsurgery in clinical practice, we herein describe the general procedures and crucial aspects to consider regarding microsurgery and supermicrosurgery training for residents. The description focuses on training methods, surgical skills, and training time and effort. The target audience of the training is residents who have never performed microsurgery. We believe that any person, regardless of operative experience, can acquire the technique for microsurgery and supermicrosurgery by performing 4 to 5 hours of training per day over a total of 30 days within this program setting. Considering individual differences in learning and experience, the training can be completed in a shorter period by performing additional daily training. It is relatively simple for a well-trained microsurgeon to master the uncommon supermicrosurgery techniques. We hope that this report will help as many residents as possible in learning the art of (super)microsurgery.

RESUMO

In the present study, we encountered a patient who developed intraabdominal lymphatic leakage after surgery for gastric cancer, underwent lymphangiography and lymphatic mass embolization, and developed severe lymphedema. The patient was a 55-year-old woman with gastric cancer with pancreatic invasion. Total gastrectomy and lymph node dissection were performed as conversion procedures. Six liters of ascites was detected postoperatively. Lymphangiography with Lipiodol injections into the bilateral inguinal lymph nodes was done three times, and Histoacryl embolization of the lymphatic leak was performed. However, edema of the lower extremities rapidly worsened. Lymphatic venous anastomosis was performed under general anesthesia. Anastomosis was performed at seven sites on the right and eight sites on the left. Postoperatively, the patient underwent compression therapy using the multilayer bandage method. The edema continued to improve further, and at 2 weeks postoperatively, the patient's weight had decreased by 21.4 kg from the preoperative weight, which was the same as that before the onset of edema. In this case, the patient's general condition was unstable due to cardiac insufficiency and other factors. Therefore, we aimed for an operation time of less than 3 hours. In addition, two surgeons performed the surgery to ensure an immediate therapeutic effect, and more anastomoses were performed than usual. After lymphatic venous anastomosis, not only the edema of both lower extremities but also the edema of the entire body improved promptly. One of the reasons for the improvement in general edema was thought to be due to increased intravascular protein and enhanced intravascular return of interstitial fluid.

RESUMO

In this report, we describe a super microsurgical technique that enables rapid and accurate anastomosis while adjusting for caliber differences when anastomosing a small-caliber lymphatic vessel and a vein with a larger caliber, which is frequently encountered in surgeries such as lymphaticovenous anastomosis (LVA).  The suture size adjustment technique was performed in 30 anastomoses of lymphatic vessels and veins, whose diameter of lymph duct was at least two times smaller than that of the vein. The type of lymphedema, caliber of lymphatic vessels and veins anastomosed, caliber ratio, vein wall thickness, modified caliber ratio after vein wall thickness subtracted, presence of additional anastomosis, and anastomosis time were examined. On average, the lymphatic vessels had a diameter of 0.61 mm, while the veins were 1.43 mm in diameter. The mean caliber ratio of vein to lymphatic vessel was 2.3, while the modified caliber ratio of vein-to-lymphatic vessel was 1.5 on average. The average venous wall thickness was 0.51. The average anastomosis time was 9.1 min and no additional anastomosis due to leakage was necessary in any case. We successfully performed an anastomosis of lymphatic vessels and veins with different calibers, which can maintain long-term patency while adjusting the caliber difference and suppressing leakage at the anastomosis site. Finally, the caliber of the vein is commonly larger than that of the lymphatic vessel to be anastomosed in many cases of LVA surgery, indicating that the proposed anastomosis method could be of therapeutic use in many cases.

RESUMO

Doppler flowmetry is one of the most popular methods of monitoring Doppler signals during reconstructive surgery of the body surface. However, because of the thick and straight structure of the shaft, it is difficult to perform in areas with limited space, such as the oral cavity. We used a new type of Doppler flowmetry shaft to postoperatively monitor the flap in the oral cavity. Compared with conventional Doppler flowmetry, the new type uses a thinner metal probe shaft that can easily be inserted in narrow and limited spaces, such as the oral cavity. Additionally, the tip of the metal probe is gently bent, thereby allowing the Doppler tip to be placed perpendicular to the surface of the skin flap. We used this new type of Doppler flowmetry shaft for 30 patients after head and neck reconstruction using free flap transfer because Doppler signals were difficult to hear using conventional Doppler flowmetry. For all 30 patients, the new Doppler flowmetry shaft was able to monitor free flaps. Vascular thrombosis or vascular spasm occurred in three patients; two patients had inadequate arterial flow caused by vasospasm and arterial thrombus, and one patient had a venous thrombus. These three patients required re-exploration, and all flaps survived. This new type of Doppler flowmetry is simple and noninvasive. Furthermore, it can easily be performed by nonphysician medical personnel, and is useful for monitoring patients after head and neck reconstructive surgery.

RESUMO

AIM: The most versatile recipient vessels for breast reconstruction are the internal mammary artery and vein. For microvascular anastomosis, one or two costal cartilages are often dissected to increase the length of the vessel and the degree of freedom. In some cases, the resection of the rib cartilage causes long-term depression at the dissected site, compromising its cosmetic appearance. PATIENTS AND METHODS: A total of 101 patients were examined, with 111 sides in which the internal mammary artery and vein were used as the recipient vessels. The patients were followed up for at least 6 months. RESULTS: A total of 37 of 38 patients with complete rib cartilage preservation had no depression, and 1 patient had a slight depression. In the case of partial resection of the rib cartilage, 37 of the 46 sides had no depression, 8 sides had mild depression, and 1 side had an obvious depression. When more than one rib cartilage was removed, 11 of the 27 sides had no depression, 11 had mild depression, and 5 had an obvious depression. The Spearman rank correlation coefficient was 0.4911936. CONCLUSION: This study reported the relationship between rib cartilage resection and postoperative concave deformity in breast reconstruction surgery using free flap transfer and the internal mammary artery and vein as the recipient vessels. A strong correlation was found between the extent of rib cartilage resected and the degree of depression. Minimizing rib cartilage resection when using the internal mammary artery and veins may minimize postoperative chest recession deformity and provide a well-dressed breast reconstruction.

RESUMO

Background: Lymphaticovenular anastomosis (LVA) has recently become a mainstream surgical treatment for lymphedema and is a useful treatment option in addition to conservative therapies such as compression therapy, exercise therapy, and lymphatic drainage. We performed LVA with the goal of stopping compression therapy and report the effect of LVA on secondary lymphedema of the upper extremities. Methods and Results: The participants were 20 patients with secondary lymphedema of the upper extremities categorized as stage 2 or 3 according to the International Society of Lymphology classification. We measured and compared the upper limb circumference at six locations before and 6 months after LVA. Significant decreases in circumference after surgery were observed at 8 cm proximal to the elbow, the elbow joint, 5 cm distal to the elbow, and the wrist joints, but not at 2 cm distal to the axilla or the dorsum of the hand. At more than 6 months postoperatively, eight patients who had been wearing compression gloves were no longer required to wear them, and three patients who had been wearing both sleeves and gloves were no longer required to wear them. Conclusions: LVA is effective in the treatment of secondary lymphedema of the upper extremities, particularly in improving elbow circumference, and is one of the treatments that contributes significantly to the improvement of quality of life. For severe cases with limited range of motion of the elbow joint, LVA should be performed first. Based on these results, we present an algorithm for upper extremity lymphedema treatment.

RESUMO

BACKGROUND: The pectoralis major musculocutaneous flap (PMMF) is a pedicled flap often used as a reconstruction option in head and neck surgery, especially in cases with poor wound healing. However, applying PMMF after esophageal surgery is uncommon. We report here, the case of a successfully repaired refractory anastomotic fistula (RF) after total esophagectomy, by PMMF. CASE PRESENTATION: A 73-year-old man had a history of hypopharyngolaryngectomy, cervical esophagectomy, and reconstruction using a free jejunal graft for hypopharyngeal carcinosarcoma at the age of 54. He also received conservative treatment for pharyngo-jejunal anastomotic leakage (AL), then postoperative radiation therapy. This time, he was diagnosed with carcinosarcoma in the upper thoracic esophagus; cT3rN0M0, cStageII, according to the Japanese Classification of Esophageal Cancer 12th Edition. As a salvage surgery, thoracoscopic total resection of the esophageal remnant and reconstruction using gastric tube via posterior mediastinal route was performed. The distal side of the jejunal graft was cut and re-anastomosed with the top of the gastric tube. An AL was observed on the 6th postoperative day (POD), and after 2 months of conservative treatment was then diagnosed as RF. The 3/4 circumference of the anterior wall of the gastric tube was ruptured for 6 cm in length, and surgical repair using PMMF was performed on POD71. The edge of the defect was exposed and the PMMF (10 × 5 cm) fed by thoracoacromial vessels was prepared. Then, the skin of the flap and the wedge of the leakage were hand sutured via double layers with the skin of the flap facing the intestinal lumen. Although a minor AL was observed on POD19, it healed with conservative treatment. No complications, such as stenosis, reflux, re-leakage, were observed over 3 years of postoperative follow-up. CONCLUSIONS: The PMMF is a useful option for repairing intractable AL after esophagectomy, especially in cases with large defect, as well as difficulties for microvascular anastomosis due to previous operation, radiation, or wound inflammation.

RESUMO

Much has been reported in the past regarding obesity as a risk factor for the origin of lymphedema. There are also reports of surgical treatments for obesity-related lymphedema. We have previously reported on the effectiveness of lymphaticovenular anastomosis in reducing chronic inflammation, and we believe that lymphaticovenular anastomosis is a very useful surgical approach in patients with recurrent cellulitis. In this report, we describe a case of a severely obese patient with a body mass index over 50 who developed lymphedema in both lower extremities due to pressure from sagging abdominal fat accompanied by frequent episodes of cellulitis.

RESUMO

BACKGROUND: The selection of recipient vessels for free-flap breast reconstruction is important for the success of the surgery and the aesthetics of the breast mound. The thoracodorsal artery and vein (TDA/V) allow reconstruction without noticeable scars from the anterior view, but TDA/V exposure is an invasive and time-consuming process on sentinel node biopsy. This study aimed to determine the effectiveness of the lateral thoracic artery and vein (LTA/V) as recipient vessels by comparing them with the TDA/V. METHODS: This study included 270 flaps that underwent immediate free-flap breast reconstruction after nipple/skin-sparing mastectomy by lateral incision. The patients were categorized into two groups (LTA and TDA) based on the recipient vessel selected. RESULTS: The LTA and TDA groups comprised 78 and 192 flaps, respectively. Among the 131 short and small pedicle flaps, such as gluteal artery perforator flap and profunda artery perforator flap, 65 (50%) used the LTA as the recipient vessel. The external diameters of the LTA/LTV (median, 1.2 mm/1.5 mm) were significantly lower than those of the TDA/TDV (median, 1.65 mm/2.0 mm). The LTV was present in 94%, and the second vein was present in 49% of cases with anastomosis. No significant differences in flap-related complications were observed between the two groups. CONCLUSIONS: The LTA/V can be used as recipient vessels for immediate free-flap reconstruction. Because of their superficial location and small caliber, they are easily accessible and suitable for short and small pedicle flaps. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

RESUMO

BACKGROUND: In super-microsurgery, such as lymphaticovenular anastomosis (LVA), the diameter of the target vessel can be small and difficult to manage, and the basic surgical technique of microsurgery, such as inserting a forceps into the lumen and applying countertraction, can be difficult. In addition, it can be difficult to confirm the success or failure of the postoperative anastomosis, unlike with normal free-flap transfer, or to learn the technique by reviewing the results. METHODS: We have described a safe, quick, and accurate technique for LVA based on our experience performing several hundred such cases at our institution. RESULTS: Before LVA, the location of the significant lymphatic vessels and veins proximal to the lymphatic vessels should be marked using indocyanine green fluorescence angiography and a vein viewer to help determine the skin incision site. We used super-microsurgical titanium needles and surgical scissors and an end-to-end anastomosis. The lymphatic vessels should be dissected as far as possible from the skin incision to the center, and the veins should be dissected as far as possible from the periphery. First, a stay suture should be applied to the upper and lower ends of the anastomosis at 180°. Next, the anterior wall should be sutured. In some cases, countertraction can be applied by inserting the tip of a forceps into the vascular vessel. However, because its insertion could damage the lymphatic vessel wall, it would be more appropriate to perform the anastomosis using the involved stitch technique. After anastomosis of the anterior wall, the vessel should be inverted and the posterior wall anastomosed using the same technique. CONCLUSIONS: We have reported the key points necessary to perform LVA quickly and accurately and the precautions necessary to maintain long-term patency. This sophisticated LVA technique can be applied to improve the outcomes for patients with lymphedema.

RESUMO

BACKGROUND Distal pancreatectomy with en bloc celiac artery resection (DP-CAR) is a curative surgical method for locally advanced pancreatic body cancer; however, arterial reconstruction remains controversial in this procedure. This report presents the case of a 47-year-old man with advanced distal pancreatic carcinoma and initial partial response to chemotherapy who required celiac axis reconstruction of the common hepatic artery and left gastric artery. CASE REPORT A 47-year-old man had loss of appetite. He had a 40-mm hypovascular tumor extending from the pancreatic body to the tail, invading around the celiac artery, common hepatic artery, left gastric artery, and splenic artery. We initiated chemotherapy concurrent with chemo-radiotherapy with S-1 administration. After chemo-radiotherapy, computed tomography (CT) showed tumor shrinkage, indicating partial response, but soft tissue CT density surrounding the celiac axis arteries persisted. We conducted conversion surgery. When the common hepatic artery was clamped during surgery, the intrahepatic arterial blood flow reduced; thus, we reconstructed the middle hepatic artery to the common hepatic artery. The left gastric artery was also reconstructed using the second jejunal artery to prevent ischemic gastropathy. Histopathologic examination showed no tumor cells in the specimen; thus, R0 resection was achieved. CONCLUSIONS Arterial reconstruction can be an option for R0 resection in DP-CAR when hepatic arterial blood flow is reduced due to an intraoperative common hepatic artery clamping test.

RESUMO

Breast size that can be reconstructed with a single flap is limited in thin patients who need bilateral autologous large-volume breast reconstruction. We present the case of a 39-year-old female with bilateral heterogeneous breast cancer. The patient underwent total mastectomy and radiation therapy on the left side and nipple sparing mastectomy on the right. We planned to use the stacked deep inferior epigastric perforator (DIEP) with sequential lumbar artery perforator (LAP) flaps because the patient's thigh was too thin and she refused using gluteal tissue. The flap was 10 cm wide at the abdomen, 5 cm wide at the waist, and 72 cm long overall. The DIEP and LAP flaps were harvested as one continuous flap and were folded onto each other to create a breast mound. The lumbar artery and vein were anastomosed to the distal stump of the deep inferior epigastric artery and vein (DIEA/V) intraflaps, and then, the proximal stump of the DIEA/V was anastomosed to the internal mammary artery and vein. The LAP flaps were placed deeply, whereas the DIEP flaps were placed superficially. Whole skin was de-epithelialized on the right side, and skin damaged by radiotherapy was released and replaced with abdominal skin on the left side. The flap survived fully, the shape of the reconstructed breasts was good, and the body line on the donor side was well maintained. We present the stacked DIEP with sequential LAP flaps as one of the options for bilateral breast reconstruction in thin patients with larger breast size.

RESUMO

BACKGROUND: Infantile hemangioma (IH) often causes cosmetic disfigurement. Early intervention with propranolol for large, high-risk lesions is recommended in the American Academy of Pediatrics' Clinical Practice Guideline. Conversely, strategies for the management of small, low-risk lesions have not been established; however, pulsed dye laser (PDL) is often used to treat these lesions. OBJECTIVE: To investigate clinical outcomes of PDL in small IH lesions. PATIENTS AND METHODS: Fifty-three cases with 58 small IHs which did not meet the criteria for high-risk lesions in the guideline and were treated only with PDL were retrospectively reviewed. The characteristics of IHs and residual skin changes after treatment were evaluated. RESULTS: Forty-seven lesions (81.0%) were superficial hemangiomas, whereas 11 (19.0%) were combined-type. The median maximum diameter was 10.0 mm. Forty-five lesions (77.6%) exhibited various residual skin changes after PDL treatment, including anetoderma (53.5%), telangiectasia and erythema (43.1%), hyperpigmentation (34.5%), redundant skin (3.4%), and fibrofatty tissue (3.4%). Of these, the incidence of anetoderma and fibrofatty tissue were significantly higher in the combined group than in the superficial group ( p = .036 and .033, respectively). CONCLUSION: Even small lesions, especially combined-type, often result in cosmetic problems after PDL treatment.

RESUMO

The aim of this study was to retrospectively estimate intervention outcomes and to establish suitable indications for autogenous tiered cartilage augmentation (ATCA) of the posterior pharyngeal wall for velopharyngeal insufficiency (VPI). The sample cohort comprised 17 consecutive patients with VPI (10 boys, 7 girls), excluding syndromic cases. Pre- and postoperative findings were comprehensively evaluated using a combination of speech assessment and lateral pharyngography (LPG). Hypernasality and consonant distortion were scored (normal: 0; mild: 1; moderate: 2; severe: 3). Velopharyngeal gap size at rest (AC) and at maximum closure (BC) were measured on LPG. All patients displayed improvements in velopharyngeal function and speech score, and no patients required re-operation. Pre- and postoperative hypernasality scores were 1.9 ± 0.5 and 0.6 ± 0.5, respectively (P < .001). Pre- and postoperative consonant distortion scores were 1.9 ± 0.6 and 0.6 ± 0.5, respectively (P < .001). Pre- and postoperative AC distances were 8.2 ± 3.4 mm and 5.9 ± 2.6 mm, respectively (P < .001). Pre- and postoperative BC distances were 3.9 ± 2.4 mm and 0.3 ± 0.8 mm, respectively (P < .001). Conclusions: ATCA appears effective for surgical treatment of VPI patients with a gap less than 10 mm.

RESUMO

BACKGROUND: In some breast cancer patients with a contralateral unaffected hypertrophic and ptotic breast, autologous small-breast reconstruction with contralateral breast reduction is a good option. The current study is aimed to assess the efficacy of the double-pedicle unaffected split-breast (USB) flap harvested from the central half of the unaffected breast for unilateral breast reconstruction with contralateral transverse scar reduction mammoplasty. METHODS: Between February 2003 and May 2020, 14 patients underwent breast reconstruction using the USB flap. The mean patient age was 59.1 (range: 48-76) years, and the mean body mass index was 24.2 (range: 19.5-33.3) kg/m2 . This flap comprised half of the contralateral breast tissues with the 3rd or 4th internal mammary perforator (IMAP) and the lateral thoracic vessel (LTA/V). After USB flap elevation and LTA/V resection, flap perfusion from the IMAP was evaluated on indocyanine green (ICG) angiography. The medial pedicle USB flap was rotated 180° and was transferred to the affected site via the midline. The LTA/V was anastomosed to the recipient vessel to supercharge the distal part of the USB flap, which was then used for breast reconstruction. Then, the remaining contralateral upper and lower breast poles were used for transverse scar reduction mammoplasty. RESULTS: The mean flap size was 13.3 × 26.9 (range: 9.5 × 22 to 16 × 29) cm. All flaps and reduced breasts survived without serious complications such as flap necrosis, although there was one patient with hematoma and one patient with hypertrophic scar. ICG revealed poor perfusion in the distal, lateral part of the flap, ranging from 22.0% to 48.5% of the overall flap area. Final aesthetic evaluation was high, with 11 cases (78.6%) being "good" or "excellent" and 3 cases (21.4%) that were either poor or fair. The mean follow-up period for the patients was 53.8 (range: 15-84) months, with none of the patients presenting second primary breast cancer or recurrence in both breasts. CONCLUSION: USB flap breast reconstruction with contralateral reduction mammoplasty is a valuable option in breast cancer patients with a hypertrophic and ptotic breast.

RESUMO

BACKGROUND: Lymphaticovenular anastomosis (LVA) is the first-line treatment for lymphedema in many hospitals. However, many aspects of its effects remain unclear. This study aimed to analyze problems with regard to the relationship between lymphaticovenular anastomosis and outcomes of surgery for lymphedema in the upper and lower extremities. METHODS: Eighteen articles were selected for review. The following information was extracted from these articles as factors associated with LVA for lymphedema in the upper and lower extremities: number of cases, average patient age, mean number of bypasses, lymphedema stage, duration and type of lymphedema, anastomotic technique, follow-up period, type of scale, and treatment outcomes. RESULTS: Upper extremity lymphedema: The average age of patients was 54.2 (range: 41.3-60.1) years. The mean number of anastomoses was 3.91 (range: 1.0-7.2). Six of nine articles provided data for volume change, and the mean volume change was 29% (-5%-50%). Lower extremity lymphedema: The average age of patients was 50.3 (range: 34-64 years). The mean number of anastomoses was 4.6 (range: 2.1-9.3). Comparison was difficult as different methods were used for postoperative evaluation (lower extremity lymphedema index in three patients, limb circumference in one, volume change in two, and restaging in three). CONCLUSIONS: We obtained useful information with regard to the effects of LVA in this review. An increased number of anastomoses between the lymphatic ducts and veins did not seem to improve the effectiveness of LVA. With regard to the stage of lymphedema, LVA may be useful for both early and advanced stages.

RESUMO

The deep inferior epigastric perforator (DIEP) flap is widely recognized as safe for use as a first-choice option in autologous tissue breast reconstruction; however, DIEP is often not performed for breast reconstruction in the elderly. We report a case of an 85-year-old woman who underwent DIEP flap reconstruction. Immediate reconstruction was performed after mastectomy. The patient successfully underwent DIEP flap reconstruction with no complications. Other options for reconstruction include a latissimus dorsi flap, a transverse rectus abdominis flap and implant-based reconstruction. DIEP flap reconstruction was performed, which does not cause muscle damage and provides sufficient volume. To our knowledge, this study is the first to report DIEP breast reconstruction in a patient over 85 years of age. This case demonstrates the usefulness of DIEP flap reconstruction for elderly patients.
