Endarterectomy for Stenosis of Less Than 50% With Symptoms
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
