目的 探讨应用指固有动脉终末背侧支皮瓣修复指端组织缺损的临床疗效. 方法 2007年3月—2011年10月,应用指固有动脉终末背侧支岛状皮瓣修复指端组织缺损6例. 结果 术后6例皮瓣全部成活,随访1~12个月,平均7.3个月,皮瓣血运良好,色泽及弹性与受区周围皮肤基本一致. 皮瓣无明确皮神经支配,感觉恢复较差,术后6~12个月,皮瓣两点辨别觉为6~8 mm,对冷热觉不敏感,对针刺等疼痛刺激有感觉. 结论 指固有动脉终末背侧支岛状皮瓣修复指端组织缺损是一种可行手术方法.%Objective To study the effect of flap based on the end dorsal branches of the digital artery on repairing of fingertip soft tissue loss. Methods From March 2007 to October 2008, the reverse flap of the end dorsal branches of digital artery was harvested for coverage of fingertip soft tissue loss for 6 cases, at the same time the reverse flap of dorsal metacarpal artery to repair dorsal donor site. Among the 6 patients, 2 cases were index fingers, 1 case was middle finger, 3 cases were ring fingers. Results All flaps survived completely. Follow-up of 1~12 months in the 6 cases, averaged 7.3 months. The blood supply and texture of the flaps was fine, and the color and elasticity was of little difference to the ambient. The skin nerves of the double flaps were not connected, and the sensibility of the flaps was poorly recovered, and the two-point discrimination was 6~8 mm in sensate flap which based on the end dorsal branches of digital artery, while it was 8-10 mm in sensate flap which based on the dorsal metacarpal artery during 6-12 months postoperative. Conclusion Double flaps based on the end dorsal branches of the digital artery and dorsal metacarpal artery is a realistic and effective method to repair fingertip defect.
