PURPOSE
The purpose of this case report is to report a rare vascular variation in the upper limbs because of its clinical importance and embryological implication.
METHODS
During the educational dissection of a 73-year-old Korean male cadaver`s right upper limb, we found a variant branch which is originated from the thoracoacromial artery.
RESULTS
The variant branch from the thoracoacromial artery ran to the distal forearm in the deep fascia. Because it finally coursed like the radial artery in the forearm and the palm, we defined the variant artery as superficial brachioradial artery (SBRA). In the cubital region a little below the intercondylar line, the brachial artery gave off a small communicating branch to SBRA, and continued as the ulnar artery.
CONCLUSIONS
We reported this unique variation and discussed its clinical and embryological implication.
目的
本病例报告旨在报告上肢一种罕见的血管变异，因其具有临床重要性和胚胎学意义。
方法
在对一名73岁韩国男性尸体的右上肢进行教学解剖时，我们发现了一条起源于胸肩峰动脉的变异分支。
结果
胸肩峰动脉的变异分支在深筋膜内向前臂远端走行。由于它最终在前臂和手掌的走行类似桡动脉，我们将这条变异动脉定义为浅表肱桡动脉（SBRA）。在髁间线稍下方的肘区，肱动脉发出一条小的交通支至SBRA，然后继续作为尺动脉走行。
结论
我们报告了这种独特的变异，并讨论了其临床和胚胎学意义。
