A carotid ultrasound is a noninvasive, painless screening test. Your doctor uses an ultrasound to look at the carotid arteries in your neck and see the flow of blood through them. Ultrasound, also called sonography, uses sound waves instead of X-rays to make images. carotid ultrasound is an important test that can detect narrowing, or stenosis of the carotid arteries. Carotid artery stenosis is a major risk factor for stroke.
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.
