View larger version (98K): [in this window] [in a new window]   Fig 1. A, Prethrombolysis. Left: The left vertebral artery angiogram shows a small filling defect (black arrow). The left P1 segment of the posterior cerebral artery is aplastic in this patient; thus, the defect could be either the basilar artery tip or the proximal-most right P1 segment. Right: Selective angiogram shows the microcatheter extending beyond the right P1 segment into the proximal lumen of the occluded artery of Percheron. Arrow indicates catheter tip. B, Post-thrombolysis. Left: The left vertebral artery angiogram shows normal visualization of the full length of the artery of Percheron (arrows) as does microcatheter selective angiograms of the artery of Percheron at center and right. The proximal occlusion of the artery of Percheron seen in Fig 1A is no longer present. C, DWI MR image obtained 24 hours after intervention shows minimal final ischemic injury.
