【摘要】 目的 探讨应用足底内侧动脉穿支蒂皮瓣修复足跟皮肤缺损的临床应用。 方法 1998年9月-2009年3月，应用此皮瓣修复足跟皮肤软组织缺损42例。术前对创面作充分准备，术中以术前彩色多普勒超声探测的足底内侧血管及穿支走向为轴心，根据需要设计皮瓣，沿皮瓣两侧向中间显露，在踇展肌与趾短屈肌之间解剖出足底内侧血管主干，显露动脉穿支及伴行神经。将血管向近端分离获得足够长度后，掀起皮瓣，切取完成并将皮瓣行明道转移修复创面。 结果 除2例术后4 d出现皮瓣远端部分坏死，经换药后愈合，其余40例皮瓣均全部成活。 结论 足底内侧动脉穿支蒂皮瓣是修复足跟软组织缺损的一种理想皮瓣。【Abstract】 Objective To study the clinical application of perforator artery flap of medial plantar in repairing skin defect of the heelstick. Methods From September 1998 to March 2009, skin defects of the heelstick of 42 patients were repaired with the perforator artery flap of medial plantar. Adequate preparations were given on the wound before operation. Based on the results of color Doppler ultrasound of the medial plantar vascellum before or during the operation, the flap was designed according to the size of the defect and transferred to repair the defect. Results All the flaps survived completely except two flaps were partial lynecrotic in the distal, which healed after change of dressing. Conclusion Perforating artery flap of medial plantar is an ideal way to repair skin defect of the heelstick.
