摘要目的 报道蒂部加强穿支血管的逆行腓肠神经营养血管筋膜皮瓣的手术方法及临床应用效果.方法 切取腓肠神经营养血管筋膜皮瓣逆行转位修复肢体远端皮肤软组织缺损时,在蒂部或转轴点附近增加从深部血管发出的皮穿支以加强皮瓣的血供,提高手术成功率.结果 临床应用24例,皮瓣面积为25 cm×12 cm～8 cm×7 cm,创面面积为全足～7 cm×6 cm;修复范围:由踝部至全足底.24例皮瓣全部成活,无皮瓣肿胀及静脉淤血.随访6～12个月,皮瓣质地优良,外形与功能恢复满意.结论 筋膜蒂部加强穿支血管的逆行腓肠神经营养血管皮瓣,血供充足,增大了皮瓣的存活面积,提高了手术的成功率,为临床修复大面积软组织缺损提供了实用性的方法.

abstractsObjective To report the operative technique and clinical results of reversed perforator-plus sural neurofasciocutaneous flap in lower leg. Methods Perforator-plus sural neurofasciocutaneous flaps, which designed along the axis of the sural nerve and based on the dual-pedicle of fasciocutaneous and per-oneal perforator, were used to reconstruct soft-tissue defect in lower extremities. Results Twenfy-four flaps, ranged from 25 cm×12 cm - 8 cm ×7 cm in size, survived completely without venous congestion and distal ischemia and necrosis. The color and texture of the flaps were good. The appearance and functional re-suits were satisfactory with following up for 6 to 12 months. Conclusion The modified technique in pediclehave minimized the complication, enlarged the size of the flap and improved the survive rates. It is a goodmethod in repairing large soft-tissue defects of extremities.
