Background The medial sural artery perforator (MSAP) flap is an increasingly versatile and reliable flap for soft tissue reconstruction. This study investigates complication rates and long‐term outcomes of the MSAP flap. Methods A retrospective review was performed on consecutive patients undergoing MSAP flap reconstruction at Chang Gung Memorial Hospital from 2006 through 2017. Patient demographics were assessed. Flap failure and wound complications were the outcome measures. Results In the cohort of 246 patients that underwent a total of 248 MSAP flap reconstructions were identified. The average age was 47.5 years (range 15–76). Of the 248 flaps, 170 were used for reconstruction of the head and neck, 48 for upper extremity reconstruction, and 30 for lower extremity reconstruction. The average MSAP flap size was 5.2 × 11.8 cm. 31 (12.5%) of the flaps developed arterial occlusion, venous insufficiency, or a hematoma postoperatively requiring re‐exploration. Nineteen were successfully salvaged, yielding an overall failure rate of 4.8%. Minor complications included the need for flap debridement in 18 cases (7.3%) and need for donor site debridement in eight cases (3.2%). Conclusions The MSAP flap can be used in a versatile fashion to reconstruct defects of the head and neck, upper extremity, and lower extremity with minimal complication rates.
