Вариантная анатомия мелких ветвей артериального круга большого мозга

Abstract

Encircling the chiasm and pituitary stalk small arteries has been studied on the autopsy material. Angio-architectonics of the small branches of the arterial circle in the brain that is connected with the chiasm and pituitary infundibulum is presented by three main groups: anterior, middle and posterior. Identified variants of the structure of the small arterial branches of the anterior part of the arterial circle in the brain are important in the estimation of collateral circulation between the branches of the internal carotid artery. Certain forms of the cerebrovascular diseases which are caused by impaired blood circulation in the vascular plexuses (superior, inferior and lateral prechiasmatic) relate to differences in the types of ramification of the anterior part of the brain arterial circle, topography and structural features of anastomoses.

На секционном материале проведено исследование мелких артерий мозга, окружающих хиазму и воронку гипофиза. Ангио-архитектоника мелких ветвей артериального круга большого мозга, связанных с хиазмой и воронкой гипофиза представлена тремя основными группами: передней, средней и задней. Выявленные варианты строения мелких артериальных ветвей переднего отдела артериального круга большого мозга, имеют значение при оценке состояния коллатерального кровообращения между ветвями внутренних сонных артерии. С различиями в типах ветвления мелких ветвей переднего отдела артериального круга большого мозга, их топографией и особенностями строения анастомозов связаны отдельные формы цереброваскулярных заболеваний, которые обусловлены нарушением кровообращения в сосудистых сплетениях (верхнем, нижнем и боковом прехиазмальном).

Keywords
