Anomalous superficial ulnar arteries were found bilaterally during routine dissection of the upper limbs of a 60-year-old male cadaver. In the left arm, the superficial ulnar artery originated from the axillary artery. It crossed the median nerve anteriorly and ran anteromedial to this nerve and the brachial artery. The superficial ulnar artery was also rudimentary and gave rise to only a narrow muscular branch to the biceps brachii. In the hand, it anastomosed with the radial artery, completing the superficial palmar arch. The radial artery was larger than usual and the deep palmar arch was formed only by the radial artery. In the right arm, the superficial ulnar artery originated from the brachial artery at the level of the inter-epicondylar line. Additionally there were "inverse palmaris longus muscles" bilaterally. This was a rare case in which the superficially ulnar artery originated from a different source on each side accompanied by anomalies of the palmar arches on one side.
在对一名60岁男性尸体的上肢进行常规解剖时，双侧发现了异常的尺侧浅动脉。在左臂，尺侧浅动脉起源于腋动脉。它在正中神经前方穿过，并在该神经和肱动脉的前内侧走行。尺侧浅动脉也发育不全，仅发出一条细小的肌支至肱二头肌。在手部，它与桡动脉吻合，形成掌浅弓。桡动脉比正常大，掌深弓仅由桡动脉形成。在右臂，尺侧浅动脉起源于肱骨髁间线水平的肱动脉。此外，双侧均有“反掌长肌”。这是一例罕见的病例，尺侧浅动脉两侧起源不同，且一侧伴有掌弓异常。
