If you are experiencing a medical emergency please dial 911 immediately
If you have 50% or more carotid stenosis (narrowing) but no symptoms, such as a previous TIA or mild stroke, the benefit may not be great enough to risk potential complications from surgery. Your doctor may recommend surgery only if you have moderate to severe narrowing and a low risk of complications from the surgery.
The American Heart Association recommends treatment with medicine for people in this category.1
