[Role of carotid artery stenting in stroke prevention].
Carotid revascularization is an effective method of primary and secondary prevention of ischemic cerebral stroke in patients presenting with extracranial carotid atherosclerosis leading to significant stenosis of the internal carotid artery. Currently, the European guidelines recommend surgical revascularization in all symptomatic patients with >50% stenosis with a documented periprocedural death/stroke risk of <6%. Endovascular revascularization should be considered in symptomatic patients with anatomical and clinical features that contribute to making such patients at high surgical risk. According to the guidelines, revascularization should be considered in patients with >60% stenosis, in the presence of clinical and/or imaging features associated with an increased risk of ipsilateral stroke (in the presence of documented risk of perioperative stroke/death <3% and patient's life expectancy >5 years). In patients with low and/or average surgical risk should be considered carotid endarterectomy, while in patients who are deemed at high surgical risk carotid stenting should be considered.Nowadays, thanks to technological advances and improved operators' experience, carotid stenting can be considered a valuable therapeutic strategy.
