以旋股外侧动脉降支供血的游离组织瓣修复小腿软组织缺损

目的 探讨以旋股外侧动脉降支逆行转位供血的游离组织瓣修复严重的小腿创伤伴软组织缺损的临床效果.方法 对小腿软组织损伤严重且无可携带游离组织瓣的血管,以旋股外侧动脉降支的远端为蒂,将其近端与游离组织瓣的动脉吻接,大隐静脉或小隐静脉与游离组织瓣的动脉伴行静脉吻接,2004年10月至2009年12月,采用该方法修复小腿软组织缺损36例,其中携带背阔肌肌皮瓣15例,股前外侧皮瓣12例,胸脐皮瓣9例.结果 36例游离皮瓣(肌皮瓣)均顺利成活,无一例出现血管危象,随访6个月至2.5年,皮瓣外形及功能恢复均较满意.结论 在小腿无可供吻合的血管时,应用以旋股外侧动脉降支逆行转位供血的游离组织瓣修复小腿软组织缺损,是一种切实有效的手术方法.

Abstract：

Objective To investigate the therapeutic effect of free tissue flap anastomosed with reverse descendant branch of lateral femoral circumflex artery for severe soft tissue defect at leg. Methods The severe soft tissue defect at leg, without any vessels for anastomosis of free tissue flap, was reconstructed with free tissue flap, which was anastomosed with proximal end of descendant branch of lateral femoral circumflex artery and great saphenous vein. From Oct. 2004 to Dec. 2009, 36 cases were treated with 15 cases of latissimus dorsi musculocutaneous flaps, 12 cases of anterolateral femoral flaps,and 9 cases of thoracoumbilicus flaps. Results All the 36 free flaps survived completely. The patients were followed up for 6 months to 2. 5 years with good cosmetic results. Conclusions It is effective and practical to repair the severe soft tissue defects at legs with the reverse descendant branch of lateral femoral circumflex artery to carry the free flaps.
