High bifurcation of the brachial artery seems to be a common variation, which can occur in many different forms, and some of them might be rather rare. We report an unusual case of bilateral high bifurcation of the brachial artery in a male cadaver. On the right arm, high origin of the ulnar artery as superficial ulnar artery was observed. The brachial artery continued and divided at the level of the elbow into radial and common interosseous artery. On the left arm, a high bifurcation of the common interosseous artery occurred, while the rest of the brachial artery continued and at the level of the elbow bifurcated into radial and superficial ulnar artery. In both arms, the common interosseous artery followed the branching pattern of the normal ulnar artery. The so formed superficial ulnar arteries gave each four common palmar digital arteries. This case is being reported for the bilaterally different variational anatomy of the upper limb arteries.
肱动脉高位分支似乎是一种常见变异，可呈现多种不同形式，其中一些可能相当罕见。我们报告一例男性尸体双侧肱动脉高位分支的罕见病例。在右臂，观察到尺动脉高位起源为尺侧浅动脉。肱动脉继续下行，在肘部水平分为桡动脉和骨间总动脉。在左臂，骨间总动脉出现高位分支，而肱动脉其余部分继续下行，在肘部水平分为桡动脉和尺侧浅动脉。在双侧手臂中，骨间总动脉遵循正常尺动脉的分支模式。如此形成的尺侧浅动脉各发出四条指掌侧总动脉。本文报告此病例是因其上肢动脉双侧不同的变异解剖结构。
