Case Report


Contrast-enhanced transoral carotid ultrasonography (CETOCU) is a novel examination modality that is superior to other modalities in the cases of pseudo-occlusion with severe arteriosclerotic stenosis of the distal internal carotid artery (ICA), and is also useful for noninvasively evaluating changes over time in the vessel distal to the stent following carotid artery stenting (CAS). We report a case of a patient who we evaluated with CETOCU for a pseudo-occlusive ICA before and after CAS.
