Summary:. Distal lower extremity wounds are a challenging problem for reconstructive surgeons and can lead to major lower extremity amputations in patients with comorbid conditions. The reverse sural artery flap (RSAF) is a local flap supplied by perforators of the peroneal artery that can cover defects of the distal lower extremity, ankle, and foot. There has been concern over performing the RSAF in patients with venous insufficiency, peripheral artery disease, and diabetes, and in older patients due to the increased risk of flap necrosis. In patients who are not microsurgical candidates, the RSAF may be the final option for reconstruction before undergoing major lower extremity amputation. We describe our experience with two patients with significant comorbidities and single vessel runoff from the peroneal artery due to atherosclerotic disease who successfully underwent RSAF reconstruction for distal lower extremity wounds.
