Thalamus Vascularisation

Abstract

Although the vasculature of the thalamus was studied for many years, but all anatomical references of groups involved are contradictory, describing the marked diversity and complexity of these descriptions of perfusion pressure does not help in formulating a sound basis for pathologists. In literature, there are few works on this theme, and are often imprecise. Macroscopic and microscopic anatomy of the trunk and related thalamic arteries isolation in relation to other trunks, even delimit vascular territories appears to be incomplete and therefore inaccurate. In this work, 6 adult human cerebellum (24 hemispheres) were dissected. With care for clarification and standardization, the extra-paren-chemical thalamic arteries were classified into six groups: pre-mamillary artery, perforating thalamic arteries, thalamic-geniculate arteries, perforating branches of the posteromedial, postero-lateral and anterior choroidal arteries.
