游离骨间背动脉穿支皮瓣移植修复手部中小面积皮肤缺损19例

目的:探讨游离骨间背侧动脉穿支皮瓣修复手部中小面积皮肤缺损的方法和临床效果。方法:彻底清创,设计与切取皮瓣,皮瓣切取面积2.0 cm×3.6 cm至4.0 cm×8.0 cm。端端或端侧吻合血管,供区进行直接缝合。结果:19例皮瓣全部成活。术后随访6~12个月,皮瓣质地及手部功能优良,供区仅留线状瘢痕。结论:骨间背动脉穿支皮瓣具有穿支动脉解剖学稳定、质地软、厚薄适中等特点,适合手部中小面积皮肤软组织缺损的修复。

Repair effect of the middle and small area skin defect of hand using free dorsal interosseous artery perforator flap in 19 cases

Objective:To investigate the surgical method and clinical effects of the free dorsal interosseous artery perforator flap on repairing the middle and small area skin defect of hand. Methods:The free dorsal interosseous artery perforator flap was obstained,the area of which was 2. 0 cm × 3. 6 cm to 4. 0 cm × 8. 0 cm. The microvascular anastomosis was implemented by end-to-end or end-to-side, the donor position was directly sutured. Results:All 19 flaps survived. The patients were followed up for 6 to 12 months. The texture of flap and hand function were good, only the linear scar was found in donor position. Conclusions:The dorsal interosseous artery perforator flap has stably anatomical structure, fine texture and suitable thickness, which is suitable for the repair of the middle and small area skin defect of hand.
