【摘要】 目的 介绍第二足趾游离移植再造拇指建立两套动脉血供的新方法。方法 游离的第二足趾移至受区后,在鼻烟窝处切断桡动脉,将足背动脉与桡动脉近端吻合，第一趾足底总动脉外侧支与桡动脉远端吻合。临床应用11例。 结果 11例再造拇指全部成活，术后均无血循环危象发生。术中发现桡动脉近、远端和游离趾动脉吻合后,能即刻通过掌深弓恢复全手血供。结论 该法是游离足趾移植再造拇指时建立两套动脉血供的良好方法，并可以达到不影响手部血供的目的。

【Abstract】 Objective To introduce a new method to build up double blood supply system in se-cond toe - to - thumb transfer. Methods After the second toe with its vascular pedicle washarvested and positioned to the hand, the radial artery was cut in the “snuff box” area. The toe was then revascularized byanastomosing the dorsalis pedis artery to the proximal end of the radial artery, andsuturing the lateral branch of the first common plantar digital artery to the distal endof the radial artery. The procedure was performed in 11 patients clinically.Results Intraoperatively,restorationof the blood supply of the hand via the deep palmar arch was promptly observed when thetwo cut ends of the radial artery were anastomosed to the vessels of the toe. There was nopostoperative circulation crisis. All the reconstructed thumbs survived. Conclusions This method ofrevascularization in toe - to - thumb transfer was not only a simple and effective methodto achieve double blood supply system for the transplant, but it also had the advantage ofnot influencing the blood supply of the hand.
