Jugular stenosis corresponds to a narrowing of the lumen of the jugular veins, which are the main blood vessels that collect oxygen-poor blood from the brain and return it to the heart and lungs to be reoxygenated and replenished with nutrients.
Jugular stenosis, by slowing down the outflow of blood from the brain, results in its stagnation with consequent reduced oxygenation of nerve cells and supporting tissues-a phenomenon that results in more or less significant cerebral “suffering” depending on the degree of stenosis and the onset of characteristic symptoms depending on the areas involved.
