RESUMO
The thyrocervical trunk is the second superior branch off the subclavian artery. Pseudoaneurysm of the thyrocervical trunk has been reported after attempted internal jugular vein cannulation for central venous or hemodialysis access. The treatment of pseudoaneurysms of the thyrocervical trunk depends on the findings from color flow Doppler ultrasonography and angiography. Although pseudoaneurysms of the thyrocervical trunk are rare, the treatment options should be clear. Surgical ligation is an effective technique that is safe and well-defined, but control through a cervical incision may be difficult. Endovascular treatment of the pseudoaneurysm may be accomplished with coil embolization of the artery, which is described.

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.
