Endarterectomy for 50% or More Stenosis Without Symptoms

For some people, the benefits of endarterectomy may not outweigh the risks. This is the case for people who have 50% or more carotid stenosis (narrowing) but no symptoms. (Symptoms include a previous TIA or mild stroke.) The American Heart Association and American Stroke Association recommend treatment with medicine and lifestyle changes for people in this category.1

Your doctor may recommend surgery only if you have moderate to severe narrowing, symptoms, and a low risk of complications from surgery.
