膝上外侧动脉穿支髂胫束皮瓣修复腘窝部瘢痕挛缩

摘要

Objective:To discuss clinical results of the lateral superior genicular artery perforator iliotibial band flap for the treatment of scar contracture of popliteal fossa. Methods: Form January 1999 to December 2011,11 patients with scar contraction of popliteal fossa were treated with the lateral superior genicular artery perforator iliotibial band flap. Among the patients , 7 patients were male and 4 patients were female, ranging in age from 24 to 58 years old, with an average of 33 years old. The operation time ranged from 3 months to 1 year after trauma. Eight patients had injuries in the right side and 3 patients had the injuries in the left. Five patients had the injuries caused by traffic, 3 patients had the injuries caused by hot compression and other 3 patients suffered from burns. The flap area ranged from 7.0 cm×4.0 cm to 20.0 cm×8.0 cm. Results:AH the flaps survived. Three patients had epidermis necrosis. After 5 months to 2 years follow-up period,the knee function recovered,the flap shape was favorable and the skin firmness was moderated. Conclusion: The lateral superior genicular artery perforator iliotibial band flap is a practical, simple and an ideal donor in the reconstruction of popliteal fossa scar contracture.%目的:探讨膝上外侧动脉穿支髂胫束皮瓣治疗腘窝部瘢痕挛缩的临床疗效,为腘窝区瘢痕挛缩寻找最佳的手术方式.方法:自2009年1月至2011年12月,应用膝上外侧动脉穿支髂胫束动脉皮瓣修复腘窝瘢痕挛缩11例,男7例,女4例；年龄24～58岁,平均33岁；病程3个月～1年,平均6.5个月；右膝关节8例,左膝关节3例；交通伤5例,热压伤3例,烧伤3例.采用膝上外侧动脉穿支髂胫束皮瓣局部转移修复创面,切取皮瓣面积最大20.0 cm×8.0 cm,最小7.0 cm×4.0 cm.结果:术后皮瓣全部成活,3例远端血运差,局部色素沉着,表皮坏死脱痂.术后随访5个月～2年,膝关节活动均恢复正常,皮瓣外形良好,皮肤松紧度适中.结论:膝上外侧动脉穿支髂胫束皮瓣实用性好,手术操作简单,是修复胭窝区瘢痕挛缩是较为理想的皮瓣选择.
