Risk assessment for carotid artery stenting

Carotid artery stenting (CAS) is an effective and increasingly utilized therapy for carotid stenosis. Despite its safety, CAS does have procedural risks, which necessitates meticulous technique and careful patient selection for this procedure. A number of patient and anatomical characteristics have been shown to increase CAS risk, and recently, prediction models have been constructed to gauge individual patient risk objectively and comprehensively. This review discusses CAS risk assessment and offers a practical approach to the management of patients with carotid stenosis for which CAS is a viable treatment option.
