The Use of Multiple Carotid Stents is Associated With Increased Incidence of Developing In-stent Stenosis on Long-term Follow-up

Abstract

Carotid artery stenting (CAS) has emerged as a feasible and safe option for patients that carry a high anatomic and/or physiologic surgical risk for conventional carotid endarterectomy. The pathophysiology behind the development of in-stent stenosis remains a complex process with multiple factors contributing to it. We sought to identify factors that contribute to developing in-stent stenosis following carotid stenting utilizing the Vascular Quality Initiative (VQI) of the Vascular Study Group of New England.
