A, Stenosis of the cavernous part of the right ICA.
B, Result after percutaneous angioplasty (3.5-mm balloon). Note irregularity at the site of the percutaneous angioplasty.
C, Cross flow from the right ICA to the contralateral hemisphere (occlusion of the left ICA is not shown). Post-procedural diffusion-weighted images (6000/103; number of excitations, one) obtained with a diffusion sensitization level of b = 1000 s/mm2.
D, New ipsilateral lesion: <5 mm, middle cerebral artery cortical territory, parietal lobe (arrow).
E, New contralateral lesion: 5 to 10 mm, middle cerebral artery cortical territory, parietal lobe (arrow).
