Application of anteromedial thigh perforator flap in repair of soft tissue defects of lower limbs

Abstract

To investigate effectiveness of anteromedial thigh perforator flap in repair of soft tissue defects of lower limbs. Between January 2015 and October 2018, 7 patients with soft tissue defects of the lower limbs were repaired with the anteromedial thigh perforator flaps. The patients were males, aged 8-30 years (median, 23 years). There were 5 cases of traffic accident injuries (the time from injury to admission was 1-4 hours, with an average of 1.5 hours), 1 case of scar formation after traffic accident, and 1 case of scar deformity after burn. The defect located in calf in 5 cases, foot in 1 case, and thigh in 1 case. The area of soft tissue defects ranged from 12 cm×4 cm to 21 cm×7 cm; and the area of flaps ranged from 14 cm×5 cm to 24 cm×8 cm. The donor sites were sutured directly. The flaps survived completely after operation in 6 cases, and the wounds healed by the first intention; the partial necrosis of flap occurred and healed after skin graft repair in 1 case. One incision partially ruptured in the donor site and healed after dressing change; the other incisions healed by the first intetion. All patients were followed up 6 months to 2 years with an average of 9 months. Except 1 case complained of edema of the flap, the other patients had good shape, good color, and no swelling. For patients with soft tissue defects of lower limbs that cannot be repaired with anterolateral thigh perforator flap, the anteromedial thigh perforator flap can be used for good results.
