Comparison of Trends and Outcomes of Carotid Artery Stenting and Endarterectomy in the United States, 2001 to 2010

Abstract

In US hospitals between 2001 and 2010, CAS was associated with worse in-hospital outcomes, partly attributable to selection and ascertainment bias. Asymptomatic patients undergoing CAS versus CEA had similar adjusted rates of major adverse events. CAS outcomes improved significantly during the course of the decade likely attributable to improvements in patient selection, operator skills, and technological advancements.
