Positional Symptomatic Occlusion of the Internal Carotid Artery: Evaluation and Surgical Management

A 42-year-old woman developed right arm and right leg weakness when turning her head to the left. A carotid angiogram, in the neutral position, demonstrated anterior deviation of the left internal carotid artery and complete occlusion of the left internal carotid artery when the head was rotated to the left. During surgery, our patient had redundant left internal carotid artery and was treated by resection and reanastomosis of the internal carotid artery. The patient's Doppler 4 months postoperatively showed widely patent arteries, and she has subsequently been asymptomatic.
