[Results of 25-years study of bifurcational aneurysms of the cerebral arteries in the cranial base]

Abstract

This publication is based on the materials of 3 officially registered discoveries, 4 monographs, 3 dissertations and a great deal of publications in the periodicals. Data on the segmental (metameric) structure of Willis' circle, articulations that connecting metameres, and on the previously unknown disease Distentio juncturarum circuli arterialis cerebri (DJCAC) involving the articulations, on the development of aneurysm-like diverticula in them. The authors are in favor of the hypothesis on the acquired (rather than congenital) origin of aneurysms (diverticula) that are an optional manifestation of DJCAC.
