High bifurcation of brachial artery with acute arterial insufficiency: a case report.

The upper extremity arterial system shows a large number of variations in the adult human body. Most of these variations occur in either the radial or ulnar artery; brachial artery variations are less common. Because the upper extremity is a frequent site of injury and various surgical and invasive procedures are performed in this region, it is of utmost importance to be aware of arterial variations. We report a case of a high bifurcation of the brachial artery presenting with acute ischemia secondary to an embolic event. The anomaly was identified, and the ischemia was successfully resolved with embolectomy.
