掌背动脉逆行岛状皮瓣修复多指皮肤缺损

目的报道应用掌背动脉逆行岛状皮瓣修复多手指软组织缺损的方法。方法应用掌背动脉逆行岛状皮瓣修复手指软组织缺损16例38指。结果术后16例38块皮瓣全部存活。随访时间为4个月～1年，皮瓣外形优良，不臃肿，皮瓣两点分辨觉为5～9mm。供区植皮成活，掌背有环形瘢痕，少许色素沉着。结论掌背动脉逆行岛状皮瓣操作方便，易切取，损伤小，不牺牲主干动脉，手术可同时切取多块皮瓣修复多指软组织缺损，是修复多手指皮肤软组织缺损的良好方法。

Dorsal metacarpal artery reverse island flap to repair skin defect of the fingers

Objective To report the method and treatment outcome of repairing soft disuse loss of the fingers with dorsal metacarpal artery reverse island flaps. Methods Sixteen eases of soft tissue loss in 38 fingers were repaired with dorsal metacarpal artery reverse island flaps. Results All 38 flaps of 16 patients survived. The patients were followed-up for 4 months to 1 year. The appearance of the flaps was good. There was no need for flap debulking. 2-PD of the flaps ranged between 5 to 9 mm. Skin graft at the donor site survived with a circular scar at dorsum of the hand. Slight pigmentation was noticed. Conclusion Dorsal metacarpal artery reverse island flap is an optimal method for coverage of soft tissue defect of the fingers. The surgery is easy and less traumatic. No major artery needs to be sacrificed. The other advantage is that multiple flaps can be harvested at the same time for coverage of defects of more than one finger.
