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

Introduction Usually the ulnar artery arises as one of the two terminal branches of brachial artery in the cubital fossa, which in turn gives rise to common interosseous artery in the upper forearm. Ulnar artery continues as superficial palmar arch in the hand by joining with superficial palmar branch of radial artery [1]. The term superficial ulnar artery is given when it arises from axillary or brachial arteries and course over superficial muscles of forearm and later joins with ulnar artery or sometimes may replace it [2, 3]. Herewith we present a case of unilateral superficial ulnar artery, which originated from the second part of axillary artery and variant termination of brachial artery into radial and common interosseous arteries with its clinical and embryological significance.
