Superficial ulnar artery (SUA) is defined as arterial variation of an ulnar artery of high origin that lies superficially in the forearm. Because an SUA may be mistaken for a superficial vein, there is a risk of arterial damage. During routine dissection of the cadaver, we incidentally detected a case of unilateral SUA in the left arm. SUA arose from the axillary artery and descended superficial to the axillary artery and median nerve. At the wrist, the SUA crossed over palmaris longus (PL) tendon from the radial side to the ulnar side. In this cadaver, the PL tendon was located on the ulnar side and was thicker than the flexor carpi radialis tendon. Clinicians should check for the presence of SUA before any technical procedure, because lack of awareness of its presence can have serious consequences.
尺侧浅动脉（SUA）被定义为高位起源的尺动脉的一种动脉变异，它位于前臂浅表位置。由于SUA可能被误认为是浅静脉，存在动脉损伤的风险。在尸体常规解剖过程中，我们偶然发现了一例左臂单侧SUA的病例。SUA起自腋动脉，在腋动脉和正中神经浅面下行。在腕部，SUA从桡侧向尺侧越过掌长肌腱。在这具尸体中，掌长肌腱位于尺侧，且比桡侧腕屈肌腱厚。临床医生在进行任何技术操作前都应检查是否存在SUA，因为对其存在缺乏认识可能会导致严重后果。
