ANATOMICAL VARIANTS OF THE CEREBRAL ARTERIAL CIRCLE IN PATIENTS WITH CEREBROVASCULAR PATHOLOGY
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.
