吻合血管第二足趾和拇甲皮瓣移植再造拇指常以足背动脉和第一跖背动脉为蒂.但在结扎切断足底深支时较困难,为了解决这一难点,本文在60例解剖研究基础上,采用以第一跖背动脉为蒂拇甲皮瓣移植,临床应用3例获得成功. The anastomosis of the second toe of the blood vessel and the thumb flap replantation of the thumb often to the dorsalis pedis artery and first dorsal metatarsal pedicle.However, it is more difficult to ligate and cut off the deep branch of the plantar, in order to solve this difficulty, On the basis of anatomical study, the first metatarsal artery pedicled with thumb flap was used. Three cases were successfully applied.
