Evaluation of the distal portion of the extracranial internal carotid artery (ICA) is indispensable for the judgment of whether surgical treatment for high-grade carotid stenosis is preferable or not. When the ICA is occluded or severely stenosed by an organic lesion along the long segment, carotid endarterectomy (CEA) is abandoned. On the other hand, CEA may be beneficial in patients with severe carotid stenosis which is situated only in the restricted lesion of the proximal portion of the ICA. Conventional carotid ultrasonography sometimes cannot provide sufficient information due to calcified plaque and/or high position of bifurcation. Newly developed transoral carotid ultrasonography (TOCU) enables us to observe the distal extracranial ICA and distinguish the differential diagnosis. We herein report 3 cases of severe carotid stenosis in which TOCU provided the necessary information obtained neither by conventional carotid ultrasonography nor by angiogram. We concluded that TOCU provides prerequisite information in certain cases in which CEA is considered.
