Background. Development of methods for diagnosing the risk of developing acute cerebral circulation disorders and their prevention requires a deep understanding of the patterns of the structure of the vascular networks of different departments of the central nervous system. Objective. To establish differences in the structure of the superficial vascular network of the upper and lower surfaces of the cerebellum and their relationship to the size and shape of the cerebellum. Methods. The study was conducted on 100 cerebellums of people of both sexes, who died of causes unrelated to brain pathology (20–95 years old). The morphometric study was carried out by the method of fractal analysis. The dependence of the fractal index values on the mass and linear dimensions of the cerebellum was studied by statistical methods: regression and correlation analysis. Results. In cerebellum with proportional shape the values of the fractal index of the upper and lower surfaces coincide practically functionally, and the mass of the cerebellum does not affect this ratio. The deviation of the shape of the cerebellum from proportional increases the differences in the structure of the vasculature on the upper and lower surface. The width of the cerebellum influences the structure of the vasculature on both its surfaces. The length of the cerebellum affects the structure of the vascular network of the lower surface more than the upper one. The height affects both surfaces of the cerebellum equally. Conclusions. The use of fractal analysis as a morphometric method and a fractal index as a morphometric criterion makes it possible to objectively characterize the structure of the cerebellar superficial vascular bed.
