With cutting-edge stroke treatment and comprehensive care at Georgia Regents Health System Advanced Comprehensive Stroke Center, our stroke experts deliver skilled and responsive stroke care for improved outomes. Stroke is caused by atherosclerosis, a progressive disease of the arteries resulting in plaque deposits. These plaque deposits can cause a narrowing or stenosis in the carotid arteries, increasing the risk for stroke. Carotid endarterectomy is a surgical procedure performed to reduce the risk of stroke in patients with severe stenosis of the internal carotid artery, and history of a transient ischemic attack (TIA) or stroke, or other significant risk factors. Carotid endarterectomy should be performed by surgeons with a complication rate of less than 6% for patients with history of TIA or stroke, and less than 3% for patients without prior TIA or stroke.
