The authors present a single-centre retrospective study in which they describe a preoperative or 90-day ipsilateral ischemic stroke risk that reaches 22% in patients with carotid near-occlusion (CNO) without full collapse and 30% for CNO with full collapse. In our registry, the rate of ipsilateral ischaemic strokes or TIA at 90 days in the group of patients who only received medical treatment ( I n i = 83) was 10.6%, and no differences were observed between patients with or without full collapse [[4]].
