Research shows that endarterectomy is not more effective than treatment with medicine for people who have symptoms, such as a previous TIA or mild stroke, but less than 50% stenosis (narrowing).footnote 1 In some cases surgery may be harmful. The procedure itself may result in more problems than benefits.
The American Heart Association and American Stroke Association recommend that these people continue treatment with medicine and healthy lifestyle changes.footnote 2
