According to a MedlinePlus article dated October 11, 2010, implanting a carotid stent is more likely to cause a stroke or death than surgically clearing blockages (carotid endarterectomy). But those patients opting for doctors cutting open the neck and scraping away the fatty deposits (endarterectomy) have greater risk for nerve damage and heart attacks.
Both therapeutic procedures are effective and have a relatively low rate of serious complications so doctors resort to one procedure over another based on what is best for the particular patient.
