Current Status of Carotid Artery Stenting.

In 2008, carotid artery stenting was formally approved in Japan. Since then, more than fourteen years have already passed. Much evidence concerning carotid artery stenting has already been published, and several new devices are available. Thus, indications and procedures for carotid artery stenting have changed. In this review, I describe the current status of carotid artery stenting by literature review with particular focus on the evidence regarding its effectiveness and safety, history with the transition of devices in Japan, and complications related to carotid artery stenting procedures. A recent topic (a new category of subtype of carotid stenosis) is also mentioned briefly.
