Outcomes and Reliability of Perforator Flaps in the Reconstruction of Hidradenitis Suppurativa Defects: A Systemic Review and Meta-Analysis.

Introduction: Hidradenitis suppurativa (HS) is a common and debilitating disease, in which the only effective treatment involves a wide excision of the affected skin. Secondary wound healing and skin grafting are two well-known options for managing these defects, but perforator flaps provide a new therapeutic alternative by ensuring reconstructions of large defects, reducing donor site morbidity, and enhancing functional recovery. The aim of this study was to achieve a systematic review of perforator flaps use in HS. Patients and Methods: PubMed and Cochrane databases were searched from 1989 to 2021. The PRISMA statement was used in the study selection process and the review was registered on PROSPERO. Furthermore, patient characteristics, operative technique, complications, and recurrences were searched. Results: Thirty-six articles were selected including 286 patients and 387 flaps. Axillary localization was mostly represented (83.2%). Direct donor site closure was achieved in 99.1% of cases. In total, 15.1% of the flaps presented at least one of the following complications: wound dehiscence (5.5%), partial necrosis (2.9%), hematoma or seroma (2.1%), infection (2.1%), venous congestion (1.8%), and nerve injury (0.3%). Two cases of total necrosis were recorded. Recurrence of the disease was observed in 2.7% of the defects. Conclusions: Pedicled perforator flaps are a reliable and reproducible technique in the reconstruction of HS defects. They are associated with a low recurrence rate while ensuring an effective reconstruction with reduced morbidity and faster recovery compared to the techniques classically used in this indication.

RETALHO SURAL REVERSO NA RECONSTRUÇÃO DE MEMBROS INFERIORES

ABSTRACTIntroduction: Reconstruction of distal wounds in lower extremities can be challenging due to the lack of tissue to perform local flaps. Fasciocutaneous and muscular flaps are some options for coverage, such as the reverse-flow fasciocutaneous sural flap.Objective: To present an 18-month experience on ankle, calcaneus, and foot reconstruction using the reverse-flow sural flap, performed by the Complex Wounds Group of the Plastic Surgery Department of the University of São Paulo Medical School.Methods: An observational, retrospective and descriptive study was performed through data survey on medical records of all patients treated between November 2018 and June 2020.Results: Nine reverse-flow fasciocutaneous sural flaps were performed. All patients were men. The mean age was 38 years old. Five patients had acute wounds for traffic collision, one electrical trauma and three chronic post-traumatic injuries. The ankle was the most common injury site (6), followed by foot (2) and calcaneus (1). Four patients had complications, three of which were partial necrosis and one distal epitheliosis. No case of total necrosis was recorded. The average hospital stay was 30.1 days.Conclusion: The reverse-flow fasciocutaneous sural flap proved to be a viable, reproducible, and reliable option for distal lower limb reconstruction.

Soft-tissue reconstruction after soft-tissue sarcoma resection: the clinical outcomes of 24 patients.

Pedicle or free-flap reconstruction is important in surgical sarcoma management. Free flaps are indicated only when pedicle flaps are considered inadequate; however, they are associated with a higher risk of flap failure, longer surgical times, and technical difficulty. To determine the skin defect size that can be covered by a pedicle flap, we investigated the clinical outcomes and complications of reconstruction using pedicle flaps vs. free flaps after sarcoma resection. We retrospectively studied the medical records of 24 patients with soft-tissue sarcomas who underwent reconstruction using a pedicle (n = 20) or free flap (n = 4) following wide tumour resection. All skin defects of the knee, lower leg, and ankle were reconstructed using a pedicle flap. Skin defects of the knee, lower leg, and ankle were covered by up to 525cm2, 325cm2, and 234cm2, respectively. The amount of blood loss was significantly greater in the free-flap group than in the pedicle flap group (p = 0.011). Surgical time was significantly shorter in the pedicle flap group than in the free-flap group (p = 0.006). Total necrosis was observed in one (25%) patient in the free-flap group; no case of total necrosis was observed in the pedicle flap group. Less blood loss, shorter surgical time, and lower risk of total flap necrosis are notable advantages of pedicle flaps over free flaps. Most skin defects, even large ones, of the lower extremities following sarcoma resection can be covered using a single pedicle flap or multiple pedicle flaps.

New technique of dissection of internal mammary vessels for breast reconstruction.

Although internal mammary vessels are considered the best recipients for free flap breast reconstruction, they present the notable drawback of limited accessibility. The aim of this study was to develop a minimally invasive surgical technique for the dissection of internal mammary vessels as recipients for breast reconstruction. From 2008 to 2018, we performed 32 unilateral microsurgical breast reconstructions (mean patient age: 40.1±8.7 years; range, 23-58 years). As internal mammary vessels were exclusively used as recipients, they were dissected using a technique of minimally invasive video-assisted thoracoscopic surgery (VATS) developed in our hospital. The mean surgery time was 5.4±0.55 hours (range, 4.5-6.5 hours), and the mean duration of VATS dissection of internal mammary vessels was 20.6±2.9 minutes (range, 16-27 minutes). Of the specific complications associated with VATS, we only observed reductions in forced expiratory volume in the first second of >15% in 3 patients (9.4%), 10-15% in 8 patients (25%), and <10% in 21 patients (65.63%). We did not have any cases of significant bleeding or postoperative infection in this series of patients. With regard to aesthetic complications, we observed 1 and 2 cases of total necrosis and partial necrosis of the deep inferior epigastric perforator (DIEP) flap, respectively and 2 cases of partial necrosis of supercharged transverse rectus abdominis muscle flap. Endoscopic dissection of internal mammary vessels is a simple and feasible technique. When performed by experienced surgeons, it is a fast procedure that is associated with low rate of complications.

The Use of Pedicled Perforator Flaps in Chest Reconstruction: A Systematic Review of Outcomes and Reliability.

In recent years, pedicled perforator flaps have revolutionized plastic surgery by reducing donor site morbidity and ensuring larger and deeper reconstructions with local pedicled cutaneous flaps. The aim of the study was to make a systematic review of perforator pedicled propeller flaps (PPPFs) in chest reconstruction. Pubmed and Cochrane databases were searched from 1989 to October 2016 for articles describing the use of PPPFs in chest reconstruction. The preferred reporting items for systematic reviews and meta analyses statement was used in the selection process. The review was registered on international prospective register of systematic reviews. Furthermore, operative technique, indications and complications were searched. Twenty-four articles were selected (174 patients and 182 flaps). Oncological surgery was the first etiology (34.5%), followed by infections (11.5%), chest keloid scars (6.23%), malformations (4.6%), burns (3.4%), chronic ulcers (2.3%), Verneuil disease (1.8%), and acute wounds (1.8%). The arc of rotation was between 90° and 120° in 24.2%. The mean surface of flaps was 127.45 ± 123.11 cm. Dissection was subfascial in 78.5% of the cases. Complications were found in 9.9% of patients and included mainly wound dehiscence (4.4%) and hematoma/seroma (2.2%). One case of total necrosis (0.5%) and 2 cases of partial necrosis (1.1%) were found. The possibility of numerous pedicles makes it possible for PPPFs to offset most areas of wall chest defects. Furthermore, this surgical technique is reliable and reproducible, with lower donor site morbidity than that in the case of muscular flaps, which are classically used in this location.
