桡动脉浅支皮瓣修复手指皮肤缺损

目的：探讨应用桡动脉浅支皮瓣修复手指皮肤缺损的方法及临床疗效。方法2008年8月-2012年1月，采用游离桡动脉浅支皮瓣修复手部皮肤缺损伴骨或肌腱外露30例，以桡动脉浅支走行于腕掌侧设计皮瓣，其中20例于皮瓣近端切取正中神经掌皮支重建感觉。皮肤缺损范围为1.5 cm×2.5 cm～2.0 cm×3.5 cm。结果本组30例皮瓣全部成活，未发生血管危象。术后随访6～12个月，皮瓣质地血运良好，外形满意，两点辨别觉为5～7 mm，供区无并发症。结论游离桡动脉浅支皮瓣切取方便，供区损伤小，是修复手指皮肤缺损较为理想的方法。

Repair of finger skin defects by superficial branch of radial artery flap

Objective To explore the clinical effects of repairing finger soft tissue defect with superficial branch of radial artery flap. Methods From August 2008 to January 2012, 30 finger defects in 20 cases were acute covered with superficial branch of radial artery flap. There were 18 males and 12 females. The age ranged from 16 to 45 years. The defect area ranged from 1.5 cm×2.5 cm～2.0 cm×3.5 cm. The flap was desigend on the palm part of wrist. The palmar cutaneous branch of the median nerve was cut in the proximal end of flap for reconstructing sensation in 20 fingers. Results All flaps survived after operation, there was no vascular crisis, and were followed up for 6 to12 months. The flaps had good appearance and texture and blood circulation. Two-point discrimination was 5～7 mm. No complication happened in donor sites. Conclusion It offered a sensation skin flap for reconstruction of defect that by transfering superficial branch of radial artery flap, for its simple cut and small damage for donor site.
