臂内侧皮神经营养血管筋膜皮瓣的临床应用

目的探讨臂内侧皮神经营养血管筋膜皮瓣修复腋部、肘部及前臂皮肤及软组织缺损的疗效。方法1999年2月～2004年12月,对18例腋部、肘部和前臂近端的皮肤及软组织缺损的患者,应用以臂内侧皮神经及其营养血管为蒂的臂内侧岛状筋膜皮瓣顺行或逆行修复上述皮肤及软组织缺损。其中男14例,女4例。年龄19～51岁。急诊手术11例,延期手术2例,择期手术5例。应用顺行皮瓣修复腋部3例,逆行皮瓣修复肘部及前臂15例。皮瓣范围4.5cm×8.5cm。结果术后3例皮瓣出现静脉危象,其中坏死1例,由于皮肤及软组织缺损较多,采用同侧的带蒂背阔肌肌皮瓣单极移位二次修复;另2例通过蒂部拆线减压,皮缘小静脉放血而成活。余15例顺利成活。所有患者获3～30个月随访,皮瓣柔软、细腻有弹性,外形佳,且恢复一定感觉。结论臂内侧皮神经营养血管筋膜皮瓣血运可靠,并含有感觉神经,手术操作简便,用于修复腋部、肘部及前臂皮肤软组织缺损是一种较理想的手术方法。

STUDY ON THE APPLICATION OF ARM MEDIAL FASCIO-CUTANEOUS FLAP PEDICLED WITH CUTANEOUS NERVE AND NUTRIENT VESSEL

OBJECTIVE: To investigate the application of arm medial fascio-cutaneous flap pedicled with cutaneous nerve and nutrient vessel. METHODS: From February 1999 to December 2004, 18 cases of skin and soft tissue defect in axillary region, elbow and forearm were treated with arm medial fascio-cutaneous flap pedicled with cutaneous nerve and nutrient vessel. Arm medial fascio-cutaneous flap was directly transferred in 3 cases, adversely transferred in 15 cases. The flap area was 4.5 cm x 8.5 cm. RESULTS: Vein circulation crisis was observed in 3 cases. Of the 3 cases, 1 was necrosis and the other 2 by decompressing small vein were saved. The rest 15 cases survived. The period of follow-up was 3 to 30 months. Flap was satisfactory in appearance and function. CONCLUSION: Arm medial fasciocutaneous flap pedicled with cutaneous nerve and nutrient vessels can be directly or adversely transferred to repair adjacent soft tissue defect.
