Abstract

Anatomical variants of the Cerebral Arterial Circle (CAC) which are associated with the high risk of cerebrovascular diseases were studied macroscopically in 425 individuals (aged 18-85) whose death had not been related to cerebral circulatory disturbances, arterial hypertension, connective-tissue diseases or diabetes mellitus. Besides, computed tomography data were obtained from 100 patients (aged 18-85) with cerebrovascular pathology. It was found that individuals with cerebral circulation disorders had only non-classical variants of CAC, which occurred in such patients more frequently (by 8-21%) than in people, whose cause of death was unrelated to this pathology. A combined CAC structure variant and the aplasia of both posterior communicating arteries appeared most frequently (by 20.8% and 18.8% respectively as compared to individuals which had no cerebral circulatory disturbances). Thus, the individuals with these CAC anatomical variants may be included into a group at risk of cerebrovascular disease development.
