腓肠神经营养血管逆行皮瓣修复儿童足踝部皮肤缺损

目的 探讨儿童腓肠神经营养血管逆行皮瓣临床应用的特点.方法 2002年1月至2007年1月,采用腓肠神经营养血管逆行皮瓣修复儿童足踝部皮肤软组织深度缺损16例,皮瓣切取面积为6.5 cm×5.0 cm～17 cm×10 cm,10例皮瓣上界超过小腿中上1/3交界处,其中2例上界达胭窝,1例上界在腘窝横纹上1.5 cm.结果 14例皮瓣全部成活;1例皮瓣远端部分坏死,1例远端浅表坏死,分别经二期缝合和换药后伤口自然愈合.经2～46个月随访,皮瓣均外观满意.结论 儿童腓肠神经营养血管逆行皮瓣存活的范围相对较大,皮瓣上界可超过小腿中上1/3交界处达腘窝横纹,是修复足踝部皮肤软组织深度缺损的理想方法.

Reconstruction of foot and ankle defect with reversed sural neurofasciocutaneous flaps in children

OBJECTIVE: To investigate the clinical application of reversed sural neurofasciocutaneous flaps in children. METHODS: From January 2002 to January 2007, 16 children patients with deep defect of foot and ankle were treated with reversed sural neurofasciocutaneous flaps. The size of the flaps ranged from 6.5 cm x 5.0 cm to 17 cm x 10 cm. The upper margin of the flaps reached the upper one-third of the leg in 10 cases, with 2 cases reaching the popliteal fossa and 1 case reaching 1.5 cm above the transverse line of popliteal fossa. RESULTS: The flaps survived completely in 14 cases. There were partial necrosis at the distal end of flap in one case and superficial necrosis at the distal end of the flap in one case. The wounds were healed spontaneously after secondary suture and dressing change. The patients were followed up for 2 - 46 months with good aesthetic results. CONCLUSIONS: The reverse sural neurofasciocutaneous flaps in children has a reliable survival area, which can reach the upper on -third of the leg until the transverse line of popliteal fossa. It is an ideal reconstructive method for deep defect of foot and ankle.
