1 The distribution and size of ischemic lesions after carotid artery angioplasty and stenting: Evidence for microembolization to terminal arteries  Lei Zhu, MD, Max Wintermark, MD, David Saloner, PhD, Madison Fandel, BS, Xian Mang Pan, MD, Joseph H. Rapp, MD  Journal of Vascular Surgery  Volume 53, Issue 4, Pages (April 2011) DOI: /j.jvs Copyright © Terms and Conditions

2 Fig 1 Diffusion-weighted images (top row) and average diffusion coefficient maps (bottom row) obtained in a 71-year-old patient imaged 48 hours after carotid stenting show multiple punctate areas of restricted diffusion in the right middle cerebral artery vascular territory, mostly in a cortical/subcortical distribution (arrows). A single lesion is seen in the periventricular white matter of the centrum semiovale. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © Terms and Conditions

3 Fig 2 Diffusion-weighted images obtained in a 62-year-old patient imaged 48 hours after carotid stenting show lesions, including a single acute lesion in the left medial occipital lobe (arrow), in the territory of the left posterior cerebral artery.

4 Fig 3 Diffusion-weighted images in a 78-year-old patient imaged 48 hours after carotid stenting show multiple punctate foci of restricted diffusion (arrows) in the left middle cerebral artery territory with lesions on the contralateral side. Again, distribution of lesions predominates at the cortico/subcortical junction, with a few lesions in the deep white matter.
