Variability of a Structure, Topography and Morphometrical Parameters Peculiarities of the Vessels of the Anterior Parts of Ircle of Willis in Human

Abstract

As a result of research variations of a structure, topography and morphometrical parameters of the vessels of anterior parts of circle of Willis of brain are revealed depending on the constitution of skull and sex. By all types of constitution of skull the classical variant of structure of the anterior parts of circle of Willis of brain discovered in 75-87% events; in 13-25% events - its variants, which characterize in large various of anatomy and morphometrical parameters. In women the diameter of the anterior artery of the brain is larger then in men on 22,6% events. Different variants of structure of the anterior artery of brain are discovered in brachiocephals most often. Мorphometrical parameters of the anterior artery of brain in brachiocephals are larger then mesocephals and dolichocephals
