The Impact of Full Collapse on the Risk of Ischaemic Stroke in Patients with Carotid Near Occlusion

Carotid near occlusion (CNO) is a severe carotid stenosis associated with a reduction in the calibre of the extracranial internal carotid artery distal to the stenosis.1 The risk of ipsilateral stroke in patients with CNO is a controversial issue. While a post hoc analysis of the North American Symptomatic Carotid Endarterectomy Trial (NASCET) and the European Carotid Surgery Trial (ECST) reported a lower risk of ipsilateral stroke for medically treated patients with CNO compared with patients with severe (70 –99%) carotid stenosis2, more recent studies have shown that the CNO recurrence rate may be higher.
