Carotid artery stenosis Carotid artery stenosis Carotid artery stenosis is a narrowing or constriction of any part of the carotid arteries, usually caused by atherosclerosis. The common carotid artery is the large artery whose pulse can be felt on both sides of the neck under the jaw. On the right side it starts from the brachiocephalic artery (a branch of the aorta), and on the left side the artery comes directly off the aortic arch. At the throat it forks into the internal carotid artery and the external carotid artery. The internal carotid artery supplies the brain, and the external carotid artery supplies
Carotid endarterectomy 7 carotid stent systems as safe and effective in patients at increased risk of complications for carotid surgery and 1 carotid stent system for patients at average or usual risk of carotid surgery. The SAPPHIRE study of patients at high surgical risk for carotid surgery demonstrated non-inferiority for carotid stenting compared to carotid surgery. The CREST trial, the largest trial comparing carotid surgery to carotid stenting in over 2,500 patients found that carotid artery stenting resulted in a stroke rate of 6.4% versus 4.7% for endarterectomy at 4 years. However, carotid endarterectomy was associated with a slightly higher rate of
