[Infundibuliform dilatations of the ostium of the posterior cerebral artery].
The authors examined 160 patients with funnel-shaped dilatation (FD) of the posterior communicating artery of the cerebrum. Initial stages of the development of an aneurysmatic sac with the corresponding histopathological changes of the arterial wall were encountered in the region of the FD. Maximum number of cases with FD were identified among individuals of the 4th to 5th decades of life. In 9.9% of cases the FD were the sources of arterial hemorrhage. FD, however, rupture less frequently than aneurysms and bleeding from them is less intensive. Surgical intervention for exclusion of the FD from circulation is the most adequate method for the treatment of this disease.
