eMedicine - Posterior Cerebral Artery Stroke : Article by Michael D Hill, MD   (Site not responding. Last check: 2007-10-20) The internal occipital artery supplies 3 end arteries: 1) the calcarine artery, which supplies the calcarine cortex on the medial surface of the occipital lobe; 2) the occipitotemporal artery, which supplies the orbital surface of the temporal and occipital lobes; and 3) the occipitoparietal artery, which supplies the precuneus and surrounding cortex. It is commonly due to embolization from the heart, the aortic arch, the vertebral artery, or the basilar artery. Occlusion of the posterior choroidal artery may produce a distinct syndrome of hemianopia, hemidysesthesia, and memory disturbance due to infarction of the lateral geniculate, fornix, dorsomedial thalamic nucleus, and posterior pulvinar. www.emedicine.com /neuro/topic322.htm   (8246 words)
