Intracranial Vertebrobasilar Artery Dissection Associated with Postpartum Angiopathy
Figure 4
(a) Baseline Xenon perfusion study (SBP 120 mm Hg) demonstrates decreased cerebral blood flow (CBF) in both posterior cerebral artery (PCA) territories as well as in the right middle cerebral artery (MCA) and left anterior cerebral artery(ACA) territories. (b) With elevation of SBP (130 mm Hg), there is improvement in CBF in the right parietal region, but no significant improvement in the left PCA territory. There is increased perfusion in the right MCA and left ACA distributions. Increased perfusion is seen within the right occipital and left parietal lobe infarctions.
