Evolution of Carotid Artery Revascularization

Since the advent of CEA in 1953, minimally invasive efforts have been developed using carotid artery stents. Carotid artery stenting (CAS) was initially developed for patients who were at high risk for stroke and were poor surgical candidates. Early attempts at carotid angioplasty were seen in the late 1990’s, and as technology has improved, it is being trialed in increasing patients.

It usually involves access through a transfemoral approach and is performed with local anesthesia with or without sedation. Most carotid artery stents use either a cobalt-chromium or nickel titanium stent. However, a slightly increased risk in periprocedural stroke and mortality with CAS has led to other minimally invasive options, such as the transcarotid approaches for carotid artery revascularization.
