小腿外侧皮瓣修复胫前和足软组织缺损

目的 报道应用小腿外侧皮瓣修复胫前和足软组织缺损的方法和临床效果。方法 1999年8月～2004年12月应用小腿外侧岛状皮瓣顺行修复胫前软组织缺损5例，逆行修复足跟、足背软组织缺损10例，游离小腿外侧皮瓣修复足背软组织缺损3例。结果 术后皮瓣全部成活。其中2例术后出现动脉危象，经拆除蒂部缝线，注射利多卡因注射液，危象解除；1例因术中意外损伤腓静脉出现皮瓣静脉危象，术后切开皮瓣边缘皮肤放血并局部滴注肝素液1周，皮瓣成活。本组均获随访2个月～1年，皮瓣无臃肿，弹性好。结论 小腿外侧皮瓣具有血管解剖恒定、厚薄适中、供区隐蔽等优点，是修复胫前和足软组织缺损的有效方法。

REPAIR OF ANTERIOR TIBIAL, DORSAL PEDAL AND CALCANEAL SOFT-TISSUE DEFECTS WITH LATERAL CRURAL FLAPS

Objective To report the methods and clinical effect of the lateral crural flaps in repairing anterior tibal, dorsal and calcaneal soft-tissue defects. Methods From August 1999 to December 2004, 18 cases of defects were repaired with lateral crural flap, including 15 cases of anterior tibal, dorsal and calcaneal soft-tissue defects with vascular pedicled island lateral crural flaps and 3 cases of dorsal pedal soft-tissue defects with free vascular lateral crural flaps.Results All flaps survived after operation. Insufficient arterial supply of the flap occurred in 2 cases after operation, the pedicled incision sewing thread was removed and lidocain was injected around vascular pedicle, then the flap ischemia was released. Inadequate venous return and venous hyperemia occurred in 1 case because peroneal vein was injured during operation.The flap edge skin was cut and heparin was locally dripped for one week, the flap vascular cycle was resumed. All patients were followed up two months to one year, the flaps were not fat, and the elasticity was good. Conclusion It is safe and reliable to use lateral crural flap to repair anterior tibial, dorsal pedal and calcaneal soft-tissue defects.
