我们在成人标本中发现一例胫前动脉分文部位较高,腓浅神经伴行动脉来源异常及腓动脉代替足背动脉的变异标本。此种变异与一些显微外科手术有密切关系,故报道如下。一、胫前动脉起始位置较高,较细,在腘肌上缘11.2mm处起于腘动脉,外径1.8mm。经腘肌深面穿过骨间膜上孔分支供应小腿前面诸肌及皮肤。但没有发出与腓浅神经伴行的动脉,也未能延续为足背动脉。二、胫后动脉干粗大,起始部外
We found in an adult specimen of the anterior tibial artery with a higher part of the site of perforation of the superficial peroneal nerve and arterial anomalies and replacement of the peroneal artery instead of the dorsalis pedis artery. This variation and some microsurgery are closely related, it is reported as follows. First, the anterior tibial artery starting higher, thinner, in the upper edge of the pterygium 11.2mm Department of popliteal artery, diameter 1.8mm. Transmucilage deep through the interosseous hole on the branch in front of the leg muscles and skin supply. However, the artery accompanying the superficial peroneal nerve had not been issued and the dorsalis pedis artery had not been extended. Second, the posterior tibial artery thick, starting Department outside
