Stroke is the third cause of death in western countries and its complications lead to significant socio-economic problems related to the prolonged hospitalization and rehabilitation of patients with neurological lesions. Severe atherosclerotic lesions of the carotid artery are the main cause of stroke and transient ischemic attacks. Their incidence may reach 5-7% per year in patients with carotid artery stenosis70% with or without symptoms. Time-honored carotid endarterectomy is still regarded as the gold standard therapy for primary and secondary prevention of stroke. However, surgery is not free of complications and the rate of perioperative stroke ranges from 5.1 to 14.3%. A group of patients at a particularly high risk of stroke during surgical endarterectomy is represented by patients with significant carotid stenosis in the presence of an occluded contralateral artery. Indeed, carotid cross-clamping during operative surgery in the absence of an adequate collateral flow may result in a critical flow reduction during the operation and therefore increases the risk of periprocedural strokes. In the North American Symptomatic Carotid Endarterectomy (NASCET) trial, the overall risk of stroke was 5.1%, whereas it increased up to 14.3% in patients with an occluded contralateral carotid artery. Recently, carotid stenting has been increasingly used as an endovascular technique for carotid revascularization, especially after the introduction of neuroprotection devices which improved the safety of the procedure. Therefore, it may be an attractive alternative to carotid endarterectomy, especially when the surgical risk is too high. We describe the immediate and late outcomes of 3 patients treated with carotid artery stenting in the presence of contralateral carotid occlusion. |
