[Carotid artery stenting - history, trends and innovations].

Surgical carotid endarterectomy is traditionally considered the standard approach for the treatment of atherosclerotic carotid artery disease based on its long history of favorable outcomes. Many of the patients could, however, be offered carotid artery stenting (CAS), which has over time evolved into an elaborate method. With proper selection of patients, CAS provides comparable long-term outcomes and very low risk of periprocedural complication. This article summarises the current knowledge, trends and innovations in CAS.
