We examined the availability of B-mode ultrasonography (B-mode) for two patients who were followed up after stenting of the carotid artery, in comparison with angiography and 3D-CT angiography (3D-CTA) . The first patient was a 60-year-old man who had suffered an episode of cerebral ischemia, and the second was a 74-year-old man who had had several episodes of unconsciousness. On admission, about 75-80% focal stenosis of the carotid artery was demonstrated in both patients by angiography, 3D-CTA and B-mode ultrasonography. Stenting of the stenosed portion was done successfully in both cases. Postoperative examination (angiography, 3D-CTA and B-mode) revealed no occurrence of restenosis. B-mode appeared especially useful for revealing details in the stent. We observed a high-echoic layer inside the stent in the first case. We suggest that B-mode is an easy and non-invasive method that is useful for follow-up after stenting in the carotid artery.
