Carotid artery angioplasty and stenting (CAS) with embolic protection has quickly become the treatment of choice for symptomatic patients felt to be too high a risk for open carotid endarterectomy secondary to co-morbidities or anatomical considerations. It is important to define not only its durability, but also the potential patients at risk for in-stent restenosis (ISR), a leading concern following arterial angioplasty and stenting. The purpose of this paper is to review ISR after CAS. To accomplish this, we will discuss: 1) identifiable risk factors; 2) etiology and evaluation; and finally 3) treatment and outcomes in patients with ISR.
