We describe rare anomalies of the bilateral superficial brachial arteries in a dissected 69-year-old Japanese man in the gross anatomical course. The right and left superficial brachial arteries were observed to originate from the axillary artery, pass over the lateral root of the median nerve, course laterally and superficially to the median nerve, and split into the radial and ulnar arteries in the cubital fossa. The right brachial artery ended in the posterior aspect of the elbow. The left brachial artery ended in the anastomosis with the ulnar artery at the site opposite to the origin of the common interosseous artery. These arterial patterns can be explained by the existence, during the developmental process of the arteries of the arm, of a superficial brachial artery and an anastomotic branch between the superficial brachial and brachial arteries.
我们描述了一名69岁日本男性尸体解剖中双侧肱浅动脉罕见的解剖变异情况。观察到右侧和左侧肱浅动脉均起自腋动脉，越过正中神经外侧根，在正中神经外侧和浅面走行，并在肘窝处分为桡动脉和尺动脉。右侧肱动脉在肘部后方终末。左侧肱动脉在与尺动脉吻合处终末，该吻合处位于骨间总动脉起点相对的位置。这些动脉走行模式可通过在手臂动脉发育过程中存在肱浅动脉以及肱浅动脉与肱动脉之间的吻合支来解释。
