Versatility of Reverse Sural Artery Flap (RSAF) in management of lower limb defects: Our experience

Abstract

Background: Wounds around the lower 1/3rd of leg and foot are difficult to manage. Treatment options like skin grafting, healing by secondary intention can result in an unstable scar. Free tissue transfers and Regional flaps has its own disadvantages. To circumvent these difficulties a fasciocutaneous flap harvested from sural angiosome was proposed. In this study, we have made an attempt to find out different scenarios in which this flap can be used as a management option and ways to minimize the complications associated with this flap. Methods: A retrospective observational study was conducted over 2 years. 30 patients were studied. Patient details was obtained from the case record, operative notes and postoperative follow-up.Results: Patients between the age of 10 years to 65 years were studied. RSA flap with adipofascial pedicle and fasciocutaneous pedicle was done in 21 and 9 patients respectively. Delaying of flap was done in 9 patients, with most common indication as distal defect. Common site of defect which were reconstructed was on the Tendoachilles region, Heel region. Various complications were loss of graft used to cover adipofascial pedicle, Venous congestion, hematoma formation and partial skin necrosis of the flap. None of the patients complained of any effect on routine activity during postoperative follow up.Conclusion: It is a versatile flap and different scenario can be managed with customization in plan. With proper selection of patients, it can be judiciously used to manage different leg defects.
