旋股外侧动脉降支侧支皮瓣修复下肢软组织缺损

目的探讨基于三维重建技术的旋股外侧动脉降支侧支皮瓣修复下肢软组织缺损的临床效果。方法 2009年3月-2010年1月,收治7例足、踝及胫前区皮肤软组织缺损患者。男6例,女1例;年龄6～51岁。交通事故伤4例,重物压伤3例。损伤部位:足部2例,踝部2例,胫前区3例。伤后至入院时间为8 h～40 d,平均20 d。创面伴骨、肌腱等组织外露,皮肤软组织缺损范围12 cm×7 cm～20 cm×14 cm。入院后对合并伤进行对症处理,4～16 d后手术。术前先行皮瓣数字化三维重建,并行皮瓣设计。术中切取大小为15 cm×9 cm～22 cm×16 cm的旋股外侧动脉降支侧支皮瓣游离移植修复缺损。供区直接缝合。结果术后皮瓣均成活,创面及供区切口均Ⅰ期愈合。患者均获随访,随访时间6～12个月。皮瓣外形、质地较好,恢复保护性感觉,能满足日常生活需要。踝关节功能满意,背伸19～22°,跖屈30～36°,正常行走。供区无明显瘢痕形成,肢体无异常。结论旋股外侧动脉降支侧支皮瓣血供可靠,操作简便,对供区影响小,术前三维重建设计可提高手术成功率,可作为修复下肢软组织缺损的理想选择之一。

CLINICAL RESULTS OF FLAP PEDICLED WITH COLLATERAL BRANCH OF DESCENDING RARUS OF LATERAL CIRCUMFLEX FEMORAL ARTERY FOR REPAIRING LOWER LIMB SOFT TISSUE DEFECTS

Objective To investigate the clinical results of the flap pedicled with collateral branch of descending rarus of lateral circumflex femoral artery with digital three-dimensional reconstruction technique for lower limb soft tissue defects.Methods Between March 2009 and January 2010,7 patients with lower limb soft tissue defects were treated with free flap pedicled with collateral branch of descending rarus of lateral circumflex femoral artery.There were 6 males and 1 female with an age range from 6 to 51 yea...
