Expanded Reverse Sural Neurocutaneous Flap for Reconstruction of Foot and Ankle Soft-tissue Defects

目的通过成功应用扩大的逆行腓肠神经营养皮瓣修复足踝部大面积皮肤软组织缺损,讨论存活的原因及手术方法。方法应用扩大的逆行腓肠神经营养血管皮瓣修复足踝部软组织损伤15例,皮瓣面积为26cm×15cm～20cm×12cm。结果所有病例中,皮瓣均成功覆盖皮肤软组织缺损处,仅1例皮瓣远端边缘坏死,经换药后愈合。术后随访3个月～2年,皮瓣成活良好。结论扩大的逆行腓肠神经营养皮瓣是可靠的,能修复足踝部大面积皮肤软组织缺损。

Objective To evaluate the application of expanded reverse sural neurocutaneous flap in the reconstruction of foot and ankle soft-tissue defects, and to discuss the survival factors and operation methods. Methed Fifteen cases of foot and ankle soft-tissue defects were treated with expanded reverse sural neurocutaneous flap. The flap area ranged from 20 cm× 15 cm to 26 cm× 20 cm. Results All soft-tissue defects were successfully covered with flaps. The distal mar- ginal necrosis occurred in 1 flap, but was healed by changing dressing. After 3 to 24 months of fol- low-up,flaps survived well. Conclusion Expanded reverse sural neurocutaneous flap is reliable in the reconstruction of foot and ankle soft-tissue defects.
