Abstract

During a routine cadaveric dissection of a 93-year-old male donor, unique arterial variations were observed in the right upper extremity. This rare arterial branching pattern began at the third part of the axillary artery (AA), where it gave off a large superficial brachial artery (SBA) before bifurcating into the subscapular artery and a common stem. The common stem then gave off a division for the anterior and posterior circumflex humeral arteries, before continuing as a small brachial artery (BA). The BA terminated as a muscular branch to the brachialis muscle. The SBA bifurcated into a large radial artery (RA) and small ulnar artery (UA) in the cubital fossa. The UA branching pattern was atypical, giving off only muscular branches in the forearm and a deep UA before contributing to the superficial palmar arch (SPA). The RA provided the radial recurrent artery and a common trunk (CT) proximally before continuing its course to the hand. The CT from the RA gave off a branch that divided into anterior and posterior ulnar recurrent arteries, as well as muscular branches, before it bifurcated into the persistent median artery (PMA) and the common interosseous artery. The PMA anastomosed with the UA before entering the carpal tunnel and contributed to the SPA. This case presents a unique combination of arterial variations in the upper extremity and is clinically and pathologically relevant.

独特的血管病例:肱浅动脉和桡侧持续正中动脉。
在对一名 93 岁男性供体进行例行尸体解剖时,在右上肢发现了独特的动脉变异。这种罕见的动脉分支模式始于腋动脉(AA)的第三部分,在那里它发出一条大的肱浅动脉(SBA),然后分叉成肩胛下动脉和一个总干。总干随后分出肱骨前和后环动脉,然后继续成为一条小肱动脉(BA)。肱动脉的末端是肱肌的肌肉分支。肱动脉在肘窝分叉为大的桡动脉(RA)和小的尺动脉(UA)。尺动脉的分支模式并不典型,仅在前臂和尺动脉深部有肌肉分支,然后才汇入掌浅弓(SPA)。RA 近端提供了桡复动脉和总干(CT),然后继续延伸至手部。来自 RA 的 CT 在分叉为持续正中动脉 (PMA) 和骨间总动脉之前,发出了一条分支,该分支分为尺侧复发动脉前部和后部以及肌肉分支。PMA 在进入腕管之前与 UA 吻合,形成 SPA。该病例展示了上肢动脉变异的独特组合,具有临床和病理意义。

期刊介绍: "Folia Morphologica" is an official journal of the Polish Anatomical Society (a Constituent Member of European Federation for Experimental Morphology - EFEM). It contains original articles and reviews on morphology in the broadest sense (descriptive, experimental, and methodological). Papers dealing with practical application of morphological research to clinical problems may also be considered. Full-length papers as well as short research notes can be submitted. Descriptive papers dealing with non-mammals, cannot be accepted for publication with some exception.
