Unilateral high origin of ulnar artery with variant bifurcation of brachial artery: a case report

Variations in the vascular system of upper limb are well documented. During routine dissection of the right upper limb of 58-year-old American female cadaver, we observed a high origin of ulnar artery from the second part of axillary artery and the variant bifurcation of the brachial artery into radial and common interosseous arteries. Awareness of these variations is necessary to avoid complications during neurovascular surgery of upper limb, and the superficial position of ulnar artery makes it more vulnerable to trauma and more accessible to cannulation.
