Carotid stenting vs surgery: parsing the risk of stroke and MI

Abstract

The Carotid Revascularization Endarterectomy Versus Stenting Trial (CREST) is the largest randomized prospective study to date to compare carotid artery stenting and carotid endarterectomy in a patient population similar to that seen in everyday practice. CREST showed stenting and surgery to be equivalent in terms of the composite end point of stroke, myocardial infarction (MI), or death within 30 days, as well as for the rate of stroke at up to 4 years (N Engl J Med 2010; 363:11-23). Importantly, the risk of major stroke was low with either intervention. However, the results need to be considered in the context of the impact of each procedure on stroke and MI.
