Fig. 3From: Perioperative stroke during carotid endarterectomy: benefits of multimodal neuromonitoring - a case reportPostoperative computed tomography perfusion imaging showing a large perfusion defect of the entire anterior circulation of the left hemisphere consistent with hypoperfusion due to severe carotid artery stenosis. A Cerebral blood volume. B Cerebral blood flow. C Time to peak. D Mean transit time. Decreased cerebral blood flow with normal cerebral blood volume indicate a small infarct core and large penumbra, e.g. salvageable tissueBack to article page
