Anterior circulation internal carotid artery system. The carotid system supplies most of the hemispheres and cortical deep white matter. The vertebra-basilar system supplies the brain stem, cerebellum and occipital lobes: anterior circulation stroke, the carotid system supplies most of the hemispheres and cortical deep white matter, the vertebro-basilar system supplies the brain stem, cerebellum and occipital lobes. Difference between dominant and non-dominant stroke: left hemisphere dominance is most common 90% of the population. Right hemisphere awareness of body and visuospatial skills, attention. Bamford classification: tacs total anterior, all of the following three. Cortical signs (ie cognitive, perceptual, aphasia: the most severe stroke, 5% of patients are alive and independent at 1 year, pacs partial anterior, two of the following three. If patients survive the acute event about.
