摘要
目的总结应用不同类型的第2掌背动脉(seconddorsalmetacarpalartery,SDMA)皮瓣修复手部组织缺损的价值。方法1998年～2003年,对139例手部皮肤或伴有肌腱缺损的患者,采用不同类型的SDMA皮瓣或带食指伸肌腱的肌腱皮瓣移植进行修复。其中男97例,女42例。年龄17～65岁,平均31.4岁。皮瓣类型:顺行岛状皮瓣37例,逆行岛状皮瓣25例,双轴点岛状皮瓣36例,皮肤返支动脉蒂岛状皮瓣19例,游离皮瓣22例。皮瓣范围3.0cm×1.5cm～6.3cm×5.0cm。结果术后135例皮瓣完全成活,3例部分成活,1例因顽固性血管痉挛而放弃手术。116例获12～57个月随访,皮瓣色泽好,外形满意。其中78例吻合神经的皮瓣浅感觉恢复好,两点辨别觉为5～9mm;未吻合神经的38例皮瓣,浅感觉恢复明显差于健侧,两点辨别觉为10～15mm。获得随访的21例肌腱皮瓣中修复伸指肌腱19例,屈指肌腱2例,手指屈伸功能按TAM法评价,可达健侧手指的60%～70%。结论采用不同类型的皮瓣或复合组织瓣移植,能修复手及其手指各部位小范围皮肤或伴有的肌腱缺损。
Objective To summarize the clinical experiences of various types of the second dorsal metacarpal artery (SDMA) flap for hand reconstruction. Methods From 1988 to 2003, 139 SDMA flaps were transferred for hand injuries. The flaps were used in 5 types according to vascularization and technique in transplantation:orthograde pedicled island SDMA flaps in 37 cases (cutaneous in 24 and teno-cutaneous in 13), retrograde pedicled island SDMA flaps in 25 cases(cutaneous in 19 and teno-cutaneous in 6),double pivot SDMA flaps in 36 cases(cutaneous in 28 and teno-cutaneous in 8), distal perforator branch pedicled flaps in 19 cases (cutaneous in 16 and composite in 3), free SDMA flaps in 22 cases (cutaneous in 15 and composite in 7). The skin islands were 3.0 cm×1.5 cm to 6.3 cm×5.0 cm in size. Results Of the 139 flaps, 135 flaps survived completely, 3 survived partially, and 1 failed in the operation because of intractable vascular spasm. Follow-up was done in 116 cases for 12 to 57 months. The flap had good texture and color match. The two-point discrimination was 5 to 9 mm in 78 sensate flaps, while it was 10 to 15 mm in 38 non-sensate flaps. In 21 tenocutaneous flaps, the TAM score of range of motion was 60% to 70% of the healthy side. Conclusion The SDMA flap has a constant and reliable vessel and a thin, pliable, and good-quality skin. It is versatile in creating composite flaps. It is a good flap resource for hand and finger reconstruction.
