Abstract
The arterial vascularization of the corpus callosum and pineal gland is still a dabatable subject. The study aims to provide detailed information about the arterial vascularization of the corpus callosum and corpus pineale. Thirty adult human brains (60 hemispheres) were obtained in routine autopsies. Cerebral arteries were separately cannulated and injected with latex. Then, the brains were fixed in formaldehyde. The dissections were carried out using a surgical microscope. The diameter of the branches of the supplying corpus callosum and glandula pinealis at their origin, vascularization areas of the branches and the variation of the arteries were investigated.The anterior part of corpus callosum that rostrum, genu end truncus were supplied by the anterior circulation. These branches were main arteries; short callosal artery, cingulocallosal arter, long callosal artery, recurren cingulocallosal artery and median callosal artery. The splenium was supplied by the anterior pericallosal artery (40%) from anterior circulation, and posterior pericallosal artery (88%) and accessory posterior pericallosal artery (50%) from posterior circulation. The main artery of the glandula pinealis was lateral pineal artery and it was originated from posterior circulation. The other arteries were medial pineal artery from posterior circulation and rostral pineal artery from anterior circulation. Posteromedial choroidal artery was important artery which were gave branches to the splenium and especially to the glandula pinealis. The arterial supplying of corpus callosum and glandula pinealis are studied comprehensiveley considering the debate and inadequacy of studies about this issue in the literature. In each hemisphere, more or less, the vascularization pattern of corpus callosum and corpus pineale is different.
