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).Reference 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.Reference 2
