Carotid endarterectomy is a surgical procedure that removes plaque and fatty deposits from blocking the carotid arteries which are the main suppliers of blood for the brain. There is strong evidence recommending carotid endarterectomy to prevent stroke in people who have severe (70 to 99 percent) blockage in their carotid artery. Nearly 25 percent of people who recover from their first stroke will have another stroke within five years. The guideline authors reviewed all of the scientific evidence on carotid endarterectomy.
The guideline found that carotid endarterectomy is effective for patients with severe stenosis (narrowing in a carotid artery) and recent symptoms of stroke or transient ischemic attack (TIA or mini-stroke). Carotid endarterectomy may also be considered for patients with moderate (50 to 69 percent) stenosis and recent symptoms of stroke.
For people between the ages of 40 75 years with moderate to severe narrowing, but presenting with no symptoms of stroke or disease, carotid endarterectomy may be considered if the patient has at least a five-year life expectancy and if the surgery can be done with a low complication rate.
"The evidence of this guideline points out an effective method of stroke prevention in certain people," said Seemant Chaturvedi, MD, guideline author and director of the Wayne State University Stroke Program. "Carotid endarterectomy is beneficial
