Long-Term Results of Carotid Stenting versus Endarterectomy in High-Risk Patients

We previously reported that, in a randomized trial, carotid stenting with the use of an emboli-protection device is not inferior to carotid endarterectomy for the treatment of carotid artery disease at 30 days and at 1 year. We now report the 3-year results.

The trial evaluated carotid artery stenting with the use of an emboli-protection device as compared with endarterectomy in 334 patients at increased risk for complications from endarterectomy who had either a symptomatic carotid artery stenosis of at least 50% of the luminal diameter or an asymptomatic stenosis of at least 80%. The prespecified major secondary end point at 3 years was a composite of death, stroke, or myocardial infarction within 30 days after the procedure or death or ipsilateral stroke between 31 days and 1080 days (3 years).
