制作1成年男性右下肢血管神经标本时,发现胫后动脉发出异常支行于外踝后方(图1),此变异罕见[1,2],为积累国人解剖学资料及为临床提供参考,现报道如下:该男尸右下肢的胫后动脉在小腿后区走行正常,其在胫骨内踝所在水平面以上0.48 cm处发出异常支,其起始处外径1.82 mm。异常支与胫后动脉呈44.5°在跟 In an adult male right lower extremity vascular nerve specimen, an abnormal branch of the posterior tibial artery was found posterior to the lateral malleolus (Figure 1). This variability is rare [1,2]. To provide a reference for the anatomy of Chinese people and for clinical application, : The posterior tibial artery of the right lower extremity of the male corpse runs normally in the posterior region of the calf. The abnormal posterior branch of the posterior tibial artery at 0.48 cm above the horizontal plane of the medial tibial ankle has an initial outer diameter of 1.82 mm. Abnormal branch and posterior tibial artery showed 44.5 ° with the
