Network of veins in the brain
The basilar venous plexus is a network of veins located at the base of the brain, specifically within the posterior cranial fossa. This venous structure plays a crucial role in the drainage of blood from the brainstem and surrounding areas.
Anatomy[edit]
The basilar venous plexus is situated around the clivus, a sloping bony surface of the occipital bone that extends from the dorsum sellae to the foramen magnum. It is closely associated with the basilar artery, which supplies blood to the brainstem and the cerebellum.
The plexus is formed by a network of interconnected veins that communicate with the cavernous sinus anteriorly and the occipital sinus posteriorly. It also connects with the internal vertebral venous plexus, which runs along the vertebral column.
Function[edit]
The primary function of the basilar venous plexus is to facilitate the drainage of venous blood from the brainstem, cerebellum, and other structures within the posterior cranial fossa. It serves as a conduit for blood to flow from the brain to the internal jugular veins, which are the main veins responsible for returning blood to the heart from the head.
Clinical significance[edit]
The basilar venous plexus is clinically significant due to its involvement in various pathological conditions. For instance, increased intracranial pressure can affect the flow of blood through this plexus, potentially leading to venous congestion and associated symptoms. Additionally, the plexus can be involved in the spread of infections or tumors from the head and neck region to the brain.
