Stroke Prevention: Extra-Cranial Carotid Artery Therapy

*Corresponding author: Christopher J. White* and Jose David Tafur Soto

Abstract

A patient-centered approach is reasonable in candidates for carotid revascularization. The patient and their physician should discuss the available treatment options, including revascularization (either carotid artery stenting (CAS) or carotid endarterectomy (CEA)) with their physician. There remains uncertainty regarding the value proposition for revascularization (either CEA or CAS) in asymptomatic patients as a strategy to prevent stroke. Investigation continues into characterizing high-risk carotid plaque subsets, but until that data is available, physicians and patients should continue to strive to achieve the best outcomes with the information that is currently available. The other consideration in asymptomatic patients is that there is a cumulative benefit to revascularization that is dependent on life expectancy. However, the magnitude of the benefit of revascularization, over the longer term in the setting of multifactorial medical therapy, including statins, is not known.
