Carotid endarterectomy (ka-ROT-id END-ar-ter-EK-to-me), or CEA, is a type of surgery that is used to prevent strokes in people who have carotid artery disease. Carotid artery disease occurs if plaque (plak) builds up in the two large arteries on each side of your neck (the carotid arteries). The carotid arteries supply your brain with oxygen-rich blood. Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood. Over time, plaque hardens and narrows the carotid arteries. This limits or blocks the flow of oxygen-rich blood to your brain, which can lead to a stroke.
