足底内侧逆行岛状皮瓣修复前足底顽固性溃疡

TREATMENT OF REFRACTORY ULCERS ON SOLE OF FOREFOOT WITH REVERSED MEDIAL PLANTAR FLAP

目的 为临床前足底顽固性溃疡的修复提供一种方法。 方法 自 1 998年起 ,应用以足底内侧血管束远端为蒂的足底内侧逆行岛状皮瓣修复前足底顽固性溃疡 5例 ,同期矫正局部畸形 ,皮瓣切取范围 3.5～ 5.0 cm×4.0～ 5.5 cm,术后注意皮瓣区近期不负重 ,保持清洁干燥。 结果 皮瓣全部成活 ,随访 6～ 1 4个月 ,皮瓣质地好 ,可见较厚角化层 ,但皮瓣痛觉迟钝 ,患足可负重行走 ,溃疡无复发。 结论 以足底内侧动静脉为蒂的逆行岛状皮瓣血运好 。

Objective To provide a new reconstructive method to treat refractory ulcers on the sole of the forefoot. Methods The reversed medial plantar flap with the medial plantar pedal artery and vein as pedicle was used to treat the refractory ulcers on the sole of the forefoot in 5 cases. The size of the flap was 3.5 5.0 cm×4.0 5.5 cm. The deformities were corrected at the same time and the flaps were protected after operation. Results All flaps survived without complications. There was no recurrence after 6 month following up. The patients could walk. Conclusion The distal ends of medial plantar pedal artery and vein have plenty anastomoses with dorsal pedal artery and deep plantar arch. The reversed medial plantar flap has reliable blood supply by these anastomoses. The reversed medial plantar flap should be a choice in treating refractory ulcers on the sole of the forefoot.
