Paradigm of aqueducts in the structure of human encephalon. Implications in pathology

G. S. Dragoi, P. R. Melinte, I. Dinca, M. M. Botoran

Abstract: The presence of hemorrhagic fluids originating from cerebral ventricles (III, IV) preferable inside cerebellummedullary and quadrigeminal subarachnoid cisterns in fetus and new born, determined the authors to make a macroanatomic analysis of fluid pathways from III and IV ventricles to adjacent subarachnoid spaces. The study was achieved on human biologic material: embryos, fetus, new born deceased before or after birth and on adult encephalon. The authors analyzed the variable topographic distribution of vertebral-basilar arterial system branches, the location for lateral aperture Luschka and the extraventricular part of choroid plexus of the fourth ventricle, the location and relations of subarachnoid cisterns and especially the quadrigeminal cistern ant they also performed an analysis of phenotype changes undergone by rhombencephalon structures during ontogenesis. Based on the results of personal observations, the authors consider that hemorrhagic fluids of the fourth ventricle flow through lateral aqueducts Luschka to cerebellum-medullary cisterns and though an aqueduct demonstrated by Bichat that opens in quadrigeminal cistern.
Keywords: aqueducts, aperture lateralis (Luschka), Bichat’s duct, quadrigeminal cistern, cerebellum-medullary cistern.
