Abstract

Antiplatelet therapy used to be the only way to prevent further cerebrovascular events in patients with carotid stenosis. After publication of final results of the European Carotid Surgery Trial (ECST) and North American Symptomatic Carotid Endarterectomy Trial (NASCET), endarterectomy was considered the best treatment option. Currently, endovascular treatment of atherosclerotic carotid artery stenosis has been established as an alternative to surgical endarterectomy. Our aim is to show the evolution of endovascular therapy in carotid stenosis, to compare outcomes between endovascular, medical and surgical treatments, and to analize the current state of endovascular therapy. It is worth underscoring that many of the studies were conducted decades ago and consequently both the endovascular technique and medical treatments used then greatly differ from current practices. Several studies agree stenting benefits patients under 70 years of age and exhibits, at least, same short-term results as endarterectomy, along with higher rate of long-term restenosis. Indication for treatment in asymptomatic patients and the use of protection systems remain an unresolved issue. A multidisciplinary team should implement an individualized treatment plan for each patient.
