Sural nerve nutrient vessels supplied retrograde island flap to repair skin defects around the ankle

目的：探讨腓肠神经营养血管逆行岛状皮瓣修复踝关节周围皮肤缺损的临床疗效。方法对12例踝关节周围皮肤缺损患者行彻底扩创，根据创面大小选择腓肠神经营养血管逆行岛状皮瓣修复。结果12例均获随访，时间6-20个月。1例术后因蒂部受压，皮瓣静脉回流不畅致远端部分坏死，经切痂植皮后痊愈；其余11例皮瓣全部成活。结论腓肠神经营养血管逆行岛状皮瓣具有操作简单、不牺牲知名血管、损伤小、皮瓣厚薄适宜、易成活等优点，是修复踝关节周围皮肤缺损的有效方法。

Objective To investigate the effect of using retrograde island flap of sural neurovascular to repair skin de-fects around the ankle. Methods 12 cases of skin defects around the ankle were completely debrided, the right flap was chosen according to the wound size to repair skin defects. Results 12 cases were followed up for 6-20 months. In one patient, partial necrosis was found in remote end flap. The patient had cured by cutting the scab, the other pa-tients′flaps were all survived. Conclusions The method of retrograde island flap of sural neurovascular repairs skin defects around the ankle without sacrificing the major blood vessels. The flap thickness is moderate. On the other hand, this operation is simple, less damage, and the flap is easy to survive.
