[Role of the large cerebral vein in active regulation of venous outflow].

Key part of venous basin of deep structures of the brain is the big vein of the brain (v. cerebri magna Galeni), which actively participates in redistribution of venous blood at heavy venous outflow from the skull cavity. Venous outflow parameters are proved to have tendency to stabilization of venous blood flow.

[Spondylogenic hypertension of deep veins of the brain].

The cerebral deep veins hypertension criteria using bloodstream in large cerebral vein (Galen's vein) are worked up. An increase in venous pressure was proved to be connected with congenital and acquired pathology of cervical spine and craniovertebral isthmus. The new roentgenologic sign of pathology located in craniovertebral isthmus is determined.

[Reaction of spinal epidural venous plexuses of the spinal canal in low back spinal discopathy].

Clinical ultrasonic investigations have shown dependence of blood-stream in spinal epidural venous plexuses on the character of low back spinal diskopathy. The leading starting factor of epiduritis is a disk protrusion or large size hernia. Epiduritis in disscopathy can run a chronic course, become a cause of (or complicate) development of vertebral neurological reflex or compression syndromes.
