Overview

Carotid endarterectomy (CEA) and carotid angioplasty are the two treatments used to reduce blockages in the carotid arteries.

CEA can lower the risk of stroke in people who have narrowed or blocked carotid arteries and symptoms suggesting stroke or transient ischemic attack (TIA). During a TIA, or "mini-stroke," you may have some or all of the symptoms of stroke. However, the symptoms usually go away on their own within 24 hours.

Carotid endarterectomy also can lower the risk of stroke in people who have severely blocked carotid arteries, even if they don't have stroke symptoms.

Carotid angioplasty is another common treatment for carotid artery disease. For this procedure, a thin tube with a balloon on the end is threaded to the narrowed or blocked artery.

Once in place, the balloon is inflated to push the plaque outward against the wall of the artery. Usually, the doctor then places a small metal stent in the artery to reduce the risk that it will become blocked again.

Antiplatelet medicines also may be used to treat people who have carotid artery disease. These medicines help reduce blood clotting and lower the risk of stroke.

Who Needs Carotid Endarterectomy?

Your doctor may recommend carotid endarterectomy (CEA) if you have carotid artery disease. CEA can help prevent strokes in people who have this condition.

CEA is most helpful for people who have carotid artery disease and one or more of the following:

• A prior stroke.
• A prior transient ischemic attack (TIA), or "mini-stroke." During a mini-stroke, you may have some or all of the symptoms of a stroke. However, the symptoms usually go away on their own within 24 hours.
• Severely blocked carotid arteries (even if you don't have stroke symptoms).

Outlook

CEA can greatly reduce the risk of stroke in people who have carotid artery disease. The surgery is fairly safe when done by a surgeon who has experience with it. However, serious complications, such as stroke and death, can occur. If you have carotid artery disease, talk to your doctor about whether CEA is an option for you.

If you've already had a CEA, you can take steps to lower your risk of future strokes. For example, get ongoing care, treat other conditions (such as high blood pressure and high blood cholesterol), and don't smoke.
