隐神经营养血管蒂逆行岛状皮瓣修复足踝部软组织缺损

目的应用隐神经营养血管蒂逆行岛状皮瓣修复组织缺损。方法以隐神经相伴行的大隐静脉体表投影为轴线，根据受区大小、部位及旋转点的位置设计逆行岛状皮瓣。结果临床应用６例，修复小腿足踝部创面，皮瓣完全成活。皮瓣面积最大６ｃｍ×８ｃｍ。经６～２０个月随访，效果满意。结论根据皮神经的血管构筑与皮肤血供密切相关的特点，设计隐神经营养血管蒂逆行岛状皮瓣安全可靠，操作简便，为小腿创面修复提供了一种可靠的新方法。

Coverage of the lower leg defects using the reversed island skin flap based on the nutrient vessels of the saphenous nerve

Objective To report the application of the distally based neurocutaneous saphenous island flap for the coverage of soft tissue defects in the lower limb. Methods According to the size and site of the defect and the rotation point, the flap was designed, and it was based on the arterial axis associated with the saphenous nerve and the greater saphenous vein. Results Six neurocutaneous saphenous island flaps were used and all survived. Flap dimensions were as large as 6 cm8 cm. The results were satisfactory after 6 to 20 months' followup. Conclusion The vascularity of the saphenous nerve is closely connected with the vascularity of the skin. The flap supplied by the accompanying vessels of the cutaneous nerve can be utilized with good results.
