Summary: The anterioabdominal wall is the most common site for low molecular weight heparin administration for anticoagulation, either for prophylactic or for therapeutic indications. Occasionally, this could be associated with damage of the abdominal pannus microvasculature, which could possibly jeopardize the reliability of free abdominal flaps as deep inferior epigastric perforator and muscle sparing transverse rectus abdominis muscle, especially with therapeutic anticoagulation therapy. These flaps are reliant on a highly intricate complex vascular anatomy and perforasomes for their adequate perfusion and survival. The authors report a case of nonobstructive microvascular failure of a free muscle sparing transverse rectus abdominis muscle utilized for soft tissue coverage following resection of a chest wall breast cancer recurrence on a background of portacath-induced deep venous thrombosis of the axillary and subclavian vein whilst on chemotherapy. History of long-term therapeutic low molecular weight heparin administration in the abdomen resulted in microangiopathic densities evident on computerized tomography scan with subsequent flap failure due to possible jeopardization of the flap microvasculature and perfusion. Following exclusion of common local and systemic factors that can cause vascular compromise, a debridement and salvage re-reconstruction procedure utilizing a contralateral free latissimus dorsi flap was performed. Reconstructive surgeons should be cautious when planning to utilize free abdominal-based flaps on the background of long-term therapeutic low molecular weight heparin administration in the abdomen and may possibly explore other alternative options of using non-abdominal free flaps from the reconstructive armamentarium within this unique context.

Background: Breast reduction techniques in management of breast cancer have been described since 1980 mainly to resect a large tumor in large breasts. Driven by the demand for more aesthetically acceptable results without compromising oncological safety, these oncoplastic approaches have become more popular. In addition, the utilization of redundant lower pole dermal flap has been a widely practiced tool in the armamentarium of implant-based breast reconstruction in patients with large ptotic breasts. The authors advocate a novel hybrid technique utilizing both therapeutic mammoplasty and lower breast pole dermal flap to provide coverage for anterior chest wall defect posttumor resection in patients with large or ptotic breasts. Methods: A retrospective review was conducted on patients who underwent chest wall resection and reconstruction using therapeutic mammoplasty and dermal flap to provide soft tissue coverage in the period between 2012 and 2018. Patient's demographics, clinicopathological, radiological, operative details, postoperative morbidity, and follow-up data were recorded. Results: Nine patients with chondrosarcoma (7/9) and giant cell tumor (2/9) were managed with a mean age 44.1 years (range 28-73). Complete oncological resection was achieved in all patients followed by rigid/nonrigid skeletal reconstructions. All procedures were completed successfully with no nipple areolar complex (NAC) necrosis or prosthesis failure experienced during the follow-up period (range 12-72 months). Excellent functional and aesthetic outcomes were reported in all patients. Conclusion: The authors' results demonstrate that this technique could be safely planned for soft tissue coverage postchest wall resection with superior aesthetic and durable outcomes.

Background: Breast conserving surgery (BCS) followed by radiotherapy has gained great popularity in the treatment of breast cancer over the past years. However, radiation therapy can lead to many unfavourable aesthetic outcomes including significant volume/skin deficiency, nipple areola complex distortion and skin contraction. We present our experience in using pedicled perforator flaps to tackle the resultant partial breast defects or deformities. Methods: A retrospective data analysis study on Thirty patients with post breast conserving surgery (BCS) partial breast defects who were managed with pedicled per-forator flaps including muscle sparing latissimus dorsi muscle flap (MSLD), thoraco-dorsal artery perforator flap (TDAP) and intercostal artery perforator flap (ICAP) in the period between December 2008 and December 2018. Results: Defects were in all quadrants apart from the upper inner quadrant. The reconstructive techniques included TDAP flap 6/30 (20%), MSLD flap 20/30 (66.7%), AICAP flap 4/30 (13.3%). Age ranges 22–35 (mean 29). All flaps showed complete survival, one nipple areola complex superficial epidermolysis was experienced, and one patient presented with fat necrosis. No resultant donor site morbidity apart from scar revision for excess skin at the axillary fold in one patient. The overall satisfaction reached 94% with only 8 patients who required lipofilling to maximize the cosmetic outcome. Conclusions: The availability of a range of reliable techniques including thoracodorsal/intercostal artery perforator flap (TAP/ICAP) and muscle sparing lattissimus dorsi flap (MSLD) allow optimum results to be achieved in the treatment of partial breast defects following breast conserving surgery.

Summary: Nipple-sparing mastectomy (NSM) with simultaneous prepectoral direct to implant reconstruction and acellular dermal matrix (ADM) is increasingly offered to patients opting for prophylactic or therapeutic mastectomies. The recent introduction of prepectoral implant/ADM in the armamentarium of breast reconstruction has proven to reduce pain and animation deformity. Despite this promising method, patients with macromastia and ptotic breasts remain a challenging group to treat. More often they would require secondary corrective procedures and can experience high failure rate and unsatisfactory outcomes. The authors present their experience in utilizing a bipedicled nipple-areola complex dermal flap through Wise pattern to achieve a successful NSM with prepectoral implant/ADM (Braxon) wrap (IBW) as a single stage in patients with large ptotic breasts. Patients seeking NSM with large ptotic breasts were included in the study in the period between 2016 and 2018. They were offered a single-stage Wise pattern NSM and immediate prepectoral IBW breast reconstruction. The technique and outcomes were recorded. Sixteen reconstructions were performed in 8 women with a median age of 32 years (range, 27–50 years) and a median body mass index of 32 kg/m² (range, 29–39 kg/m²). The resected breasts weight ranged from 750 to 1,600 g (median, 890 g). All procedures were completed successfully with no nipple-areola complex necrosis or failure experienced during the follow-up period (range, 3–24 months) with all patients reported excellent satisfaction. The authors’ results demonstrate that this technique could be safely planned for NSM in large ptotic breasts with excellent durable outcomes.

Background: Tenets of chest wall reconstruction for malignancy are well known; however, the insertion of synthetic prosthetic material to achieve rigid and nonrigid skeletal reconstruction could be associated with more complications including infection and extrusion especially in high risk patients. This includes fungating, infected tumors, previous radiotherapy, scars, smoking, diabetes, and morbid obesity. Bioprosthesis Acelluar Dermal Matrix Strattice would be a substitute to resist infection and provide stable coverage. Methods: A retrospective data analysis study on 8 high-risk patients who underwent chest wall resection and reconstruction with bioprosthesis (Strattice) with/without titanium plates in the period between 2012 and 2017 was performed. Patient’s demographics, risk factors, clinico-pathological, radiological, operative details, adjuvant therapy, postoperative morbidity, and follow-up data were recorded. Results: Sarcoma was the pathology in 7 and recurrent breast cancer in 1 with age range from 21 to 71 years (mean, 50) and preponderance of female patients (n = 5). Defects were located anterior/anterolateral with size ranging from 270 to 1,050 cm² (mean, 511). Reconstruction was performed using Strattice only in 4 patients, whereas in 4 it was combined with titanium plates. All patients required flap reconstruction (3 pedicled and 5 free). The follow-up ranged from 9 to 52 months (mean, 24.8). Minor complications occurred in 2 patients; however, good functional outcome was achieved in all. Conclusion: Strattice would act as a safe alternative modality for chest wall reconstruction to resist infection in high-risk patients with extensive defects. It should be considered as a valuable tool in the armamentarium of chest wall reconstruction.

Background The internal mammary lymph node (IMLN) basin is considered the second most important regional nodal basin in breast cancer. IMLNs are often not detected radiologically and left untreated, with symptomatic recurrence being 0.1%. Challenges in accessibility have been an obstacle in achieving a comprehensive treatment plan, especially with undetermined and radiologically enlarged IMLN. Free autologous tissue breast reconstruction is considered the gold standard, and the familiarity of microvascular surgeons in using the internal mammary vessels (IMVs) puts them in a unique position to shed more light on the natural pathological process of IMLN metastases. Materials and Methods A retrospective data analysis study was conducted evaluating 270 patients who underwent 307 free flaps for breast reconstruction using the IMV in the period between 2009 and 2017. Patient's demographics and clinicopathological data including IMLN harvest, radiological, operative details, adjuvant therapy, postoperative morbidity, and follow-up outcome data were analyzed. Results Eighty-nine enlarged IMLNs were surgically retrieved from 30.7% (83/270) of the patients (73 delayed, 10 immediate breast reconstructions) with an age range of 29 to 77 years (mean: 45). Eighty six were incidentally encountered during surgery, whereas in three, the enlarged IMLN was preoperatively, radiologically determined and biopsied during computed tomography (CT) scan staging and was retrieved subsequently during surgery. IMLN metastases were confirmed in 8.4% (7/83) of the patients in whom IMLNs were retrieved with subsequent modification of the proposed adjuvant therapy. The follow-up period ranged from 3 to 84 months (mean: 42) for the involved IMLN patients. Two patients (28% [2/7]) showed signs of disease progression with mortality. Conclusion Microvascular surgeons in a multidisciplinary setting would provide a valuable role in improving outcomes of patients with IMLN metastases through better diagnosis and staging of incidentally enlarged metastatic IMLN and provision of an effective approach for locoregional disease control.

The management of recurrent rectovaginal fistula after obstetric injury and cryptoglandular sepsis is considered a major surgical challenge. The fistula poses a significant negative psychosocial and sexual morbidity. In addition, the poor quality of local tissues due to previous attempts at surgical repair adds to this challenge. There are few data regarding the management of persistent or recurrent fistula in the literature; however, several studies reported high failure rates after 2 or more procedures. We present 4 cases managed successfully in a multidisciplinary approach involving fistulectomy and immediate reconstruction with an internal pudendal artery perforator island flap.
