Clinical Results of Carotid Artery Stenting (CAS) in Patients over 80 Years Old: Strategy and Usefulness of Tailored-CAS Algorithm Based on Lesion Morphology and Plaque Characteristics

Purpose: Carotid artery stenting (CAS) reduces the risk of ischemic stroke in patients with carotid artery stenosis, although recent randomized trials showed an increase in periprocedural stroke risk in elderly patients undergoing CAS. Recently, the safety and efficacy of tailored-CAS was reported. We retrospectively compared the clinical results of tailored-CAS between patients >80 and <80 years old.
