What is a carotid endarterectomy?

Carotid Endarterectomy

A carotid endarterectomy is a surgery to remove plaque buildup from your carotid arteries. It is a treatment for carotid artery disease and can help prevent a stroke. Carotid endarterectomy involves opening the carotid arteries in your neck and removing the inner lining that has become diseased or damaged by plaque.

You have two carotid arteries, one on each side of your neck. They are the major arteries that carry blood from your heart to your brain. A buildup of plaque can narrow or block your carotid arteries. This is called carotid artery disease, and it puts you at risk of stroke.

A carotid endarterectomy is a major surgery with significant risks and potential complications. You may have less invasive treatment options. Consider getting a second opinion about all of your treatment choices before having a carotid endarterectomy.

Other procedures that may be performed

Your doctor may perform one or more diagnostic procedures in addition to a carotid endarterectomy. These procedures will tell your doctor how much plaque is in your carotid arteries. They include:

  • Carotid angiography is a procedure that allows your doctor to take a picture or image (called an angiogram) of your carotid arteries

  • Carotid ultrasound is a noninvasive, painless screening test that allows your doctor to examine your carotid arteries and evaluate the flow of blood through them.
