摘要目的 报告应用下腹部单蒂三叶薄皮瓣修复三指套脱伤的手术方法及临床疗效.方法 2007年3月至2009年4月,对11例示、中、环指套脱伤患者,应用下腹部旋髂浅动脉为轴心血管的双叶薄皮瓣及阴部外浅动脉为轴心血管的单叶薄皮瓣,使其形成以股动脉主干为蒂的三叶薄皮瓣,修复手指皮肤缺损,4周后行皮瓣断蒂术.结果 术后4周断蒂,皮瓣全部存活.术后随访6～ 12个月,平均8.7个月.皮瓣外形好,质地柔软,无瘢痕挛缩,患指活动正常,皮瓣恢复部分感觉功能；患者对皮瓣外形较满意.结论 单蒂三叶薄皮瓣修复手指皮肤套脱伤,不需二期分指植皮,减轻了患者的痛苦及经济负担.

abstractsObjective To report the surgical technique and treatment outcomes of lower abdominal three-leaf flap based on a single pedicle in treating degloving injuries of three fingers. Methods Eleven cases of degloving injury of the index,middle and ring fingers were treated between March 2007 and April 2009.Double flaps with superficial iliac circumferential artery as the axial artery and a single flap with superficial external genicular artery as the axial artery were combined to form a three-leaf flp based on the femoral artery.The flaps were transferred to cover the skin defects of the fingers.The pedicle was divided 4 weeks later.Results All the flaps survived after dividing the pedicle 4 weeks later.Postoperative follow-up ranged from 6 to 12 months,with an average of 8.7 months.The flaps had acceptable appearances,soft texture and no scar contractures.Movement of the affected fingers was normal.The flaps gained partial sensation.The patients were satisfied with the flap appearances. Conclusion Three-leaf flap based on a single pedicle is an ideal option for treating multiple finger degloving injury.There is no need for second stage finger separation and skin graft.This largely reduces patient suffering and financial burden.
