指动脉岛状皮瓣在手指软组织缺损中的应用

Application of digital artery island flap for soft tissue defects of finger

目的探讨指动脉岛状皮瓣修复手指软组织缺损的疗效。方法2003年8月-2004年11月，我科应用指动脉岛状皮瓣修复手指软组织缺损25例，皮瓣面积（2．0-3．0）cm×（1．5—3．0）cm。结果25例皮瓣全部成活。手术时间60-90min，平均75min。术中出血量25-40ml，平均32ml。2例植皮面1／3面积坏死，换皮后愈合。23例随访6—18个月，平均13．5月，皮瓣色泽红润，质地正常，外形佳，皮瓣两点分辨觉为6．5—8．8mm，平均7．5mm，温、痛觉恢复良好，手指感觉运动功能均满意。结论指动脉岛状皮瓣手术操作简单，疗效满意，是修复手指软组织缺损的理想术式。

Objective To investigate the effectiveness of repair of soft tissue defects of finger by using the digital artery island flap. Methods A total of 25 cases of soft tissue defects of finger were treated by using the digital artery island flap in this department from August 2003 to November 2004. The flap was 2.0 - 3.0 cm× 1.5 - 3.0 cm in size. Results The flap had survived in all the 25 cases. The operation time was 60 - 90 min （ mean, 75 min）, and the intraoperative blood loss was 25 - 40 ml （ mean, 32 ml）. The skin graft necrosed by one - third of area in 2 cases, which was cured by a re - grafting. Follow - up observations in 23 cases for 6 - 18 months （ mean, 13.5 months） revealed the flaps with normal color, elasticity, and appearance. The static two - point discrimination was 6.5 - 8.8 mm （mean, 7.5 mm）. The digital pain and temperature sensation had recovered to normal, and the patients reported satisfactory sensory and motor functions. Conclusions Characterized by simple performance and satisfactory outcomes, digital artery island flap is an ideal choice for the coverage of soft tissue defects of finger.
