Figure 1 Preoperative angiograms (A and B) from Patient 1 show a 99% stenosis of the left internal carotid artery (ICA) (arrow in A) with delayed filling of the ICA compared with the external carotid artery (arrowhead in A) as well as an 80% stenosis of the origin of the right ICA (arrow in B). Computerized tomography scan of the brain (C) performed 1 h following left carotid stenting shows a large basal ganglia hemorrhage with mild subarachnoid hemorrhage.
