    Abstract:
    We report a case of bilateral arterial variation in the upper extremities of a male cadaver. In the left upper extremity, it was observed that the ulnar artery was arising from axillary artery. This ulnar artery was superficial throughout its course at the medial aspect of the arm and forearm. It was highly tortuous and did not have any branches either in the arm or forearm. It ended as the superficial palmar arch in the palm. However the brachial artery entered the cubital fossa and divided into radial and common interosseus arteries. In contrast, the right upper extremity was having normal brachial artery which was terminated into the ulnar and radial arteries at the cubital fossa. However, there was an accessory brachial artery present at the arm and ended at the cubital fossa. We believe that these anatomical variations are because of abnormal developmental vascular pattern in the region. In clinical practice, accurate knowledge of the arterial variations of upper extremity is of considerable importance in case of reparative surgeries and fracture management. They are of interest to the vascular and plastic surgeons.
