Abstract: A sound knowledge of vascular anatomy of upper limb is of paramount importance, since this is a site of frequent injury and of various surgical and invasive procedures. The term Accessory brachial artery was first established by McCormack. During the routine cadaveric dissection of upper limb of a middle-aged male cadaver, a bilateral variation in the upper limb arteries was observed. Unusual bilateral accessory brachial arteries were arising from the axillary artery, proximal to the intercondylar line of humerus. They were then continuing in the forearm as accessory ulnar artery. The main brachial arteries were dividing into radial and ulnar arteries bilaterally in the cubital fossa. At the wrist, below the flexor retinaculum it was involved in the formation of superficial palmar arches. An accurate knowledge of anatomical variation of brachial artery course, branching, termination and course of its terminal branches are essential prerequisite during surgeries.
