Abstract

We report a 70-year-old man with bilateral occlusion of the carotid bifurcation, diagnosed by preoperative carotid ultrasonography. He was admitted for surgical treatment of a giant thoracic aortic aneurysm, and had a history of frequent TIAs and right hemiparesis. Contrast-enhanced 3D-MR angiography and conventional angiography confirmed bilateral occlusion of the carotid bifurcations. Since such a condition is very rare, we discuss the diagnostic value of carotid ultrasonography and its clinical significance.
