Unusual branching pattern of brachial artery - Embryological basis and clinicoanatomical insight.

Variations in the arterial pattern of upper limb are of colossal importance to the surgeons as they are liable to iatrogenic injuries. During routine dissection for undergraduate medical students, an anomaly of brachial artery was discovered. The brachial artery terminated at higher level into ulnar and radial artery. The common interosseus artery took origin arising from radial artery. The ulnar artery did not give any branches in the forearm. Both radial and ulnar artery displayed a superficial course in the forearm. The anatomical knowledge of these variations may be of great help for the clinicians in planning and conducting flap harvesting during reconstructive surgeries and in arteriography.
