Introduction to Venous Multiple Sclerosis
Chronic cerebrospinal venous insufficiency... it’s a chronic (ongoing) problem where blood from the brain and spine has trouble getting back to the heart. It’s caused by stenosis (a narrowing) in the veins that drain the spine and brain. Blood takes longer to get back to the heart, and it can reflux back into the brain and spine or cause edema and leakage of red blood cells and fluids into the delicate tissue of the brain and spine. Blood that stays in the brain too long creates “slowed perfusion”...a delay in deoxyginated blood leaving the head. This can cause a lack of oxygen (hypoxia) in the brain. Plasma and iron from blood deposited in the brain tissue are also very damaging.
This is a very short, concise definition. The procedure to fix the problem is angioplasty of the jugular veins and sometimes the azygous (chest) vein. When the drs find it hard to keep the collapsed or twisted vein open stents are sometimes placed in the area.
