目的　报道游离隐动脉皮瓣修复手足部皮肤软组织缺损的临床效果。　方法　2003年2月～2009年2月，对8例手部皮肤软组织缺损患者，5例足部皮肤软组织缺损患者，采用游离隐动脉皮瓣修复术。13例患者均伴有肌腱、骨、神经血管外露，皮瓣面积7cm×6cm～12cm×9cm，1例小儿患者足跟部皮肤软组织缺损伴有跟腱缺损，2例皮瓣供区采用直接缝合，11例皮瓣供区采用下腹部全厚皮片植皮。　结果　术后13例患者皮瓣均一期成活，供区伤口一期愈合。经随访6～36个月，平均随访9个月。皮瓣质地优良，外观不臃肿，感觉恢复S2~S4，手部功能恢复满意，足部行走功能无影响。2例供区直接缝合者供区遗留线状瘢痕，瘢痕无增生及挛缩，11例供区植皮者植皮区松软，外观可，无瘢痕挛缩。　结论　游离隐动脉皮瓣修复手足部皮肤软组织缺损，具有解剖恒定，手术操作安全、简便，可满足手足部创面覆盖的需要。

Objective　To report the clinical effects of the dissociative saphenous arteria flap on repairing hand and foot soft tissue defect.　Methods　From Feb. 2003 to Feb. 2009, 8 cases of hand skin soft tissue defect and 5 cases of foot skin soft tissue defect were treated with dissociative saphenous arteria flaps. All the 13 cases were accompanied with exposed tendons，bones and nerves, and the flap area was about 7cm×6cm～12cm×9cm，while achilles tendon defect appeared in one child patient. Donor areas of 2 cases were stitched up directly, however, donor areas of 11 cases were replanted with total pachydermia of hypogastrium. 　Results　The flaps of all 13 cases survived after surgery, and the wound of donor area healed primarily. Our follow-up lasted for 6~36 months, averagely 9 months. It showed that, the flaps survived well, with no swelling and distension. The sensory recovery reached about S2~S4. The loss of the function of hand and foot did not appeared for all cases. Linear scars on donor area can be found for 2 cases with direct stitches, with no hyperplasia or contracture, while, donor areas of 11 cases were soft and neat, without scar or contracture. Conclusions　The application of dissociative saphenous arteria flap in repairing and reconstructing of hand and foot soft tissue defect were with anatomical invariableness, with safe and convenient operation, and with the need of recovering the wound surface of hand and foot.
