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).1
In some cases surgery may be harmful—the procedure itself may result in more
problems than benefits.
The American Heart Association guidelines recommend
that these people continue treatment with medicine.2
