Carotid near-occlusion is a rare condition characterized by a full or partial collapse of the lumen of the internal carotid artery beyond tight stenosis of the carotid bulb. This condition, especially in the case of full collapse, is associated with a greater risk of cerebral ischemic events. Color Doppler ultrasound can provide a useful diagnostic support by visualizing the stenosis and the collapsed vessel. CT angiography allows a better visualization of the vessel beyond a tight stenosis and allows to differentiate between full or partial collapse of the vessel. Regarding the therapeutic approach, the debate between revascularization through stents and endoarterectomy is interesting: the first option seems to be the most suitable and has the best outcome for the patient. In this article we illustrate the case of a patient with carotid near-occlusion with full collapse of the vessel and report CT angiography features.
