Variations in the vascular system of upper limbs are relatively common, with considerable significance towards the clinical and surgical point of view. The major arterial variations reported are of high origins of radial and ulnar arteries. During routine dissection of an upper extremity in the Department of Anatomy, Medical University of the Americas, Nevis, West Indies, a variation in the origin of the radial artery from the axillary artery was observed in the right upper limb of a 55-year-old female cadaver. The normal and variant origin of the radial artery has pragmatic importance for surgeons and radiologists. Also, the superficial position of an artery makes it vulnerable to injury during cannulation, which may lead to pseudoaneurysm.
上肢血管系统的变异相对常见，从临床和外科角度来看具有相当重要的意义。所报告的主要动脉变异是桡动脉和尺动脉的高位起源。在西印度群岛尼维斯美洲医科大学解剖学系对一具上肢进行常规解剖时，在一名55岁女性尸体的右上肢观察到桡动脉起源于腋动脉的变异情况。桡动脉正常和变异的起源对外科医生和放射科医生具有实际重要性。此外，动脉的浅表位置使其在插管过程中容易受到损伤，这可能导致假性动脉瘤。
