改良带腓肠神经营养血管远端蒂逆行岛状皮瓣修复足踝部皮肤缺损

CLINICAL APPLICATION OF IMPROVED ISLAND SKIN FLAP WITH DISTALLY-BASED SURAL NERVE NUTRIENT VESSELS

目的总结改进带腓肠神经营养血管远端蒂逆行岛状皮瓣修复足踝部皮肤缺损的临床效果。方法2004年8月~2005年4月,对15例足跟、踝关节和足前部皮肤缺损患者,应用以腓肠神经营养血管链为皮瓣提供血供,设计逆行岛状皮瓣进行修复,蒂部最远可达外踝平面。其中切取单纯皮瓣12例,复合皮瓣3例,皮瓣范围7cm×6cm^11cm×8cm。供区伤口直接缝合或游离植皮覆盖。结果术后15例皮瓣全部成活,无皮瓣肿胀或血运障碍,供、受区创面均期愈合。术后获随访3~6个月,皮瓣外形满意,质地柔软,色泽与受区近似,无局限性臃肿,能穿鞋正常行走,皮瓣受力处无破溃,足部功能恢复良好。结论带腓肠神经营养血管远端蒂逆行岛状皮瓣修复足、踝部皮肤缺损不需吻合血管,操作简便,安全可靠,是修复足踝部皮肤缺损的理想皮瓣。

Objective To report the clinical result of the improved island skin flap with distally-based sural nerve nutrient vessels in repairing skin defect in the heel, ankle or foot. Methods From August 2004 to April 2005, 15 patients with skin defect in the heel, ankle or foot at distal part were treated by the improved island skin flap with distally-based of sural nerve nutrient vessels. Of 15 flaps, 12 were simplex flaps and 3 were complex flaps. These flap area ranged from 7 cm × 6 cm to 11 × 8 cm. The donor sites were sutured directly and covered with free flap. Results All flaps survived without flap swelling and disturbance of blood circulation. The wounds of donor and recipient sites healed by first intention. The follow-up period ranged from 3 to 6 months. The texture of flap was soft and the color of flap was similar to that of normal skin. The foot function was excellent. Conclusion The improved island skin flap with distally-based sural nerve nutrient vessels is an ideal skin flap for repairing skin defect in the heel, ankle or foot distal part in clinical. The operation is simple and need not to anastomose blood vessel.
