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.
上肢动脉系统在成年人体中表现出大量变异。这些变异大多发生在桡动脉或尺动脉；肱动脉变异较少见。由于上肢是损伤的常见部位，且该区域会进行各种外科手术和侵入性操作，因此了解动脉变异至关重要。我们报告一例肱动脉高位分叉并继发于栓塞事件的急性缺血病例。该异常被识别出来，通过取栓术成功解决了缺血问题。
