The work presents the morphological characteristics of the structures of the venous sinuses of the brain at the macro-microscopic level. Various types of formations on the inner walls significantly affect the movement of blood in the lumen of the sinuses. Some structures stabilize the sinus wall by strengthening its fibrous framework, others counteract stretching and tearing, and others absorb pulse oscillations when changing physical factors. However, the greatest morpho-functional attention is attracted by formations that are derivatives of the arachnoid membrane of the brain and spinal cord - pachyon granulations. Traditionally, granulations have been thought to significantly affect the mechanisms of CSF circulation in the closed cranial cavity, but recent evidence suggests that they mediate the occurrence of cerebral venous thrombosis, which disproportionately affects young people and can be fatal. Although recent attention has been drawn to thrombosis-related strokes in connection with COVID-19 vaccines, our understanding of this condition remains limited and largely unexplored.
