目的：评价外踝上动脉降支蒂逆行皮瓣修复踝、足部软组织缺损的临床疗效。方法：自2009年5月至2013年10月利用外踝上动脉降支蒂逆行皮瓣修复踝、足部皮肤缺损合并肌腱、骨外露12例，男9例，女3例；年龄19～58岁，平均37.5岁。足背软组织缺损10例，踝部软组织缺损2例。缺损面积最大11 cm×9 cm，最小8 cm×5 cm.结果：12例均获随访，时间3～12个月，平均7.3个月。9例皮瓣全部成活；3例皮瓣远端边缘坏死，经换药治愈。皮瓣除轻度肿胀外，无溃疡等发生。结论：外踝上动脉降支蒂逆行皮瓣修复足部软组织缺损一期手术即可完成，具有血供可靠、切取简单安全、不损伤小腿的主要血管等优点。

Lateral supramalleolar artery descending branch antidromic flap for the repair of soft tissue defects in the foot and ankle

Objective: To evaluate the effect of lateral supramalleolar artery descending branch antidromic flap for the repair of soft tissue defects in the foot and ankle. Methods: From May 2009 to October 2013,12 patients with soft tissue defects combined with tendon and bone exposure in the foot and ankle were treated by lateral supramalleolar artery descending branch antidromic flap for the repair of soft tissue defects in the foot and ankle,including 9 males and 3 females with an average age of 37.5 years old ranging from 19 to 58 years. Ten cases had the soft tissue defects in the dorsum of foot and 2 in the ankle. The defect area of soft tissue was from 11 cm×9 cm to 8 cm×5 cm. Results: Twelve patients were follow-up for 3 to 12 months(averaged 7.3 months). The flaps of 9 cases were survived,the flaps edges of the other 3 cases were necrosis,and healed after dressing change. The flaps were slightly swelling without ulcer occurrence. Conclusion: Lateral supramalleolar artery descending branch antidromic flap can repairing the damage by one-stage operation with advantage of dissection easy,rich blood supply without sacrifice of major artery.
