Carotid endarterectomy removes plaque from the carotid artery in the neck to lower the risk of stroke. The surgeon makes an incision in the neck, opens the artery, removes the plaque and closes the artery, often with a patch. Blood flow to the brain is protected during the operation. It is considered when the artery is significantly narrowed, particularly if the patient has already had warning symptoms.

How the Procedure Can Help

By clearing the narrowing, the operation reduces the chance of a stroke that could affect movement, speech and vision. Many patients leave hospital within a few days.

Risks and Considerations

Stroke, heart attack, bleeding in the neck and injury to nearby nerves, causing hoarseness or a drooping lip, are possible. The artery can narrow again, so follow-up scans, medicines and control of blood pressure, cholesterol and diabetes continue lifelong. Stenting may be an option for some patients.
