Arterial variations in the arm are of potential clinical implications as it is a frequent site of injury and also involved in many surgical and invasive procedures. During a dissection of the right upper extremity, an abnormal high origin of the radial and ulnar arteries was found. The brachial artery had a very short segment without any branches, divided into the radial and ulnar arteries at the upper third of the arm. The course and branching pattern of these radial and ulnar arteries in the arm are discussed. It was also observed that the profunda brachii artery was represented by two separate branches arising from the posterior circumflex humeral artery. Accurate knowledge of these variation patterns is of considerable clinical importance in the conduct of reparative surgeries around the shoulder and fracture management of the humerus. These additional data of arterial anomalies to contemporary anatomical literature are of interest to clinicians, in particular vascular and plastic surgeons and radiologists.
