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
