目的 研究趾动脉终末支岛状皮瓣重塑再造指外形的可行性.方法 2008年3月至2009年12月,对17例(19指)手指缺损游离足趾移植再造的患者,术中同时采用足趾趾动脉终末支岛状皮瓣转移嵌入第二趾颈部,消除因该部位狭窄导致的再造指外形的缺陷.结果 术后再造19指及嵌入趾颈部狭窄处皮瓣全部存活,供受区伤口Ⅰ期愈合.随访时间为6～17个月,平均8个月.再造指外形得到明显改善,指腹感觉恢复良好,两点分辨觉为8～12 mm.结论 应用趾动脉终末支岛状皮瓣重塑再造手指外形,解决了再造指指腹膨大和掌侧颈部狭窄的外形缺陷,临床疗效较好.%Objective To study the feasibility of using toe artery terminal branch island flap for remodeling and reconstruction of finger shape. Methods From March 2008 to December 2009,19 fingers of 17 cases that were reconstructed by toe transfer had the toe artery terminal branch island flap inserted in the neck of the second toe during the toe transfer surgery to correct the appearance deficit caused by the narrow area. Results All 19 reconstructed fingers and the inserted toe artery terminal branch island flaps survived after the surgery. Donor site wound had primary healing. Postoperative follow-up lasted 6 to 17 months,with an average of 8 months. The appearance of reconstructed fingers was greatly improved. There was good recovery of pulp sensation,with two-point discrimination being 8 to 12 mm. Patients feel quite satisfied. Conclusion Toe artery terminal branch island flap corrects the deficit in appearance of fingers the palm side of the finger.
