目的 探讨flow-through静脉皮瓣在复杂性断指再植中的应用方法及临床疗效. 方法 2011年3月-2012年8月,对15例复杂性断指采用带双套静脉回流系统的前臂flow-through静脉皮瓣游离移植重建断指血运,并一期修复创面,受伤至手术时间1.5-5.5 h(平均2.5 h),血管缺损长度1.5 - 11.0 cm(平均3.6 cm);皮肤软组织缺损范围1.5 cm×3.0 cm - 11.0 cm×11.0 cm,所有患指均有严重软组织缺损及节段性血管缺损,指体血运障碍. 结果 术后1例出现静脉危象,经血管移植后缓解,1例皮瓣远端部分坏死,经二期植皮后愈合;其余断指、皮瓣均顺利成活,切口均Ⅰ期愈合.术后14例获随访7-20个月,末次随访皮瓣色泽、质地好,温、痛、触觉恢复,患指按断指再植功能评定试用标准评定,优7例,良5例,差2例. 结论 Flow-through静脉皮瓣可同时重建断指血运并修复创面,带双套静脉回流系统可有效缓解术后静脉淤血,提高成活率,扩大皮瓣切取面积,术后患指外观、功能恢复好,适用于伴节段性血管缺损及皮肤缺损的断指再植.
Objective To analyze the outcome of applying venous flow-through flap in replantation of complex severed finger.Methods From March,2011 to August,2012,15 cases of complex severed fingers were repaired by flow-through flap with two sets of venous system of forearm vein and one stage repair of wound.The time from injury to operation was 1.5-5.5 h (mean 2.5 h).Vascular defect length ranged from 1.5 to 11.0 cm (mean 3.6 cm);and soft tissue defect of 1.5 cm × 3.0 cm to 11.0 cm × 11.0 cm.All digits had severe soft tissue defect and segmental defect of blood vessels.All the finger blood circulation was disorder.Results All flaps and replanted fingers survived completely,except 1 case of postoperative venous crisis occurred which was remission after the vascular transplantation,and 1 case of skin flap necrosis at the distal part which was healed after skin grafting; Fourteen cases were followed-up from 7 to 20 months.At the final followed-up the flaps were of good consistency and appearance.Function of the finger was graded excellent in 7 cases,good in 5 cases,and poor in 2 cases.All flaps and replanted fingers survived completely over a period of 12 to 30 months follow-up.The flaps were of good consistency and appearance.Function of the finger was graded excellent in 7 cases and good in 5 cases.Conclusion With less injury at donor site,and good repair results,venous flow-through flap is well indicated in complex finger replantation with soft tissue defect and vascule defect.
