Thalamic and Other Posterior Cerebral Artery Stroke Syndromes

The posterior cerebral arteries (PCAs) are the terminal branches of the basilar artery and supply blood to the rostral midbrain, the thalamus, the occipital lobes, and part of the parietal and temporal lobes including the hippocampus. Classically, it has been distinguished a proximal or deep PCA territory (including the thalamus) and a distal or superficial PCA territory (including the occipital and temporoparietal lobes).
