How Venous Drainage of the Brain Works

Watch how this important vein network functions and its potential role in IIH

In this video, Geeky Medics explains how venus drainage of the brain works by examining the superficial and deep veins of the cerebrum and how they drain into the dural venous sinuses.

When the venous sinuses are narrowed or blocked, it can affect the pressure in the brain and the flow of blood and cerebrospinal fluid throughout the brain. Venous sinus stenosis (VSS) is when the venous sinuses are narrowed. This can cause an increased pressure in the brain and impaired drainage of cerebrospinal fluid and deoxygenated blood in the brain. This process will cause a person to experience debilitating headaches, visual changes, papilledema, have an increased opening pressure on lumbar puncture, and countless other symptoms. These described findings and many other symptoms are seen in IIH – learn more about VSS and its role in IIH.
