目的解剖观测趾足底固有动脉趾端动脉弓及其分支的解剖学特点。方法选取新鲜成人足标本8只,分别经足背动脉灌注红色乳胶,对第2趾趾足底固有动脉进行显微解剖,观察趾足底固有动脉弓的出现概率,位置及其口径,趾端动脉弓发出的弓上动脉的起始部位,走行方向,分支数目及血管口径情况。结果第2趾趾足底固有动脉趾端动脉弓恒定,动脉弓的外径为0.5~0.8 mm,平均外径为0.64 mm,动脉弓距趾端的距离为9.5~13.0 mm,平均为11.1 mm。动脉弓上发出5支恒定的分支,即趾端弓上动脉,我们将其命名为第1~5支趾端弓上动脉(由胫侧至腓侧)。结论第2趾趾端动脉弓及其发出的弓上动脉解剖恒定,可以采用弓上动脉为蒂的微型轴型皮瓣改善第2足趾再造后外形。
Objective To dissect the anatomical features of the arch and branch of the toe of the toe of the plantar attila. Methods Eight fresh adult foot specimens were selected. The red latex was infused through the dorsalis pedis artery to dissect the second plantar artery of the toe, and the appearance probability, location and caliber of the natural plantar arch of the toe were observed. Aortic arch issued by the starting part of the artery on the bow, walking direction, the number of branches and vascular caliber. Results The arch of the C2 toe of the second toe was constant. The diameter of the arch was 0.5-0.8 mm and the average diameter was 0.64 mm. The distance between the arch and the toe of the artery was 9.5-13.0 mm with an average of 11.1 mm. Five constant branches of the aortic arch emerge, the toe arch, and we name it the first to fifth branch of the dorsal toe arch (from the tibia to the fibular side). Conclusions The second toe-toe-end arch and its arch superior to the ankle are constant anatomical. The mini-axial pedicle pedicle pedicle can be used to improve the appearance of the second toe after reconstruction.
