A 71-year-old man who underwent protected carotid artery stenting with a filter device.

A. Pre-stenting angiogram shows a severe string like stenosis of the left internal carotid artery. The post-stenotic distal internal carotid artery is also narrow compared with the external carotid artery (pseudo-occlusion).

B. A filter device is deployed in the distal carotid artery (arrow).

C. After carotid artery stenting, the lumen of the left internal carotid artery is successfully dilated.

D. No ischemic lesion is shown in bilateral cerebral hemispheres on the pre-stenting diffusion weighted MR imaging.

E. Multiple small new hyperintensities are observed in the ipsilateral cerebral hemisphere on the post-stenting diffusion-weighted MR images. However, no symptomatic neurological complications occurred after carotid artery stenting.
