Beginning in 1937 Batson began a series of injection experiments investigating the anatomy and physiology of the cerebrospinal venous system. [2] His carefully documented results demonstrated the continuity of the venous systems of the brain and the spine, as injections of contrast dyes into venous systems feeding into the spinal venous plexus led to the appearance of contrast material in the ...
This continuous flow into the venous system dilutes the concentration of larger, lipid-insoluble molecules penetrating the brain and CSF. [9] CSF is normally free of red blood cells and at most contains fewer than 5 white blood cells per mm 3 (if the white cell count is higher than this it constitutes pleocytosis and can indicate inflammation ...
Chronic cerebrospinal venous insufficiency (CCSVI or CCVI) is a term invented by Italian researcher Paolo Zamboni in 2008 to describe compromised flow of blood in the veins draining the central nervous system. [1] [2] Zamboni hypothesized that it might play a role in the cause or development of multiple sclerosis (MS).
The dural venous sinuses (also called dural sinuses, cerebral sinuses, or cranial sinuses) are venous sinuses (channels) found between the periosteal and meningeal layers of dura mater in the brain. [ 1 ] [ 2 ] They receive blood from the cerebral veins , and cerebrospinal fluid (CSF) from the subarachnoid space via arachnoid granulations .

Batson's plexus is part of the Cerebrospinal venous system. Batson's venous plexus may also allow the spread of infection in a similar manner. neuroschistomiasis, [ 9 ] Urinary tract infections like pyelonephritis have been shown to spread to cause osteomyelitis of the vertebrae via this route.
Cranial venous outflow obstruction, also referred to as impaired cranial venous outflow, impaired cerebral venous outflow, cerebral venous impairment is a vascular disorder that involves the impairment of venous drainage from the cerebral veins of the human brain. [1] [2] The cause of cranial venous outflow obstruction is not fully understood.
The meningeal lymphatic system is composed of a network of vessels along the dural sinus in the dura which express lymphatic endothelial cell marker proteins, including PROX1, LYVE1, and PDPN. The vessels extend along the length of both the superior sagittal and transverse sinuses and directly connects to the deep cervical lymph nodes. [ 1 ]
