Cerebral Venous Thrombosis and Stroke

The brain, like every other organ in the body, has a venous system which carries blood back towards the lungs, where it is replenished of oxygen. Sometimes under certain circumstances a blood clot forms inside one of the venous branches, causing a back-up of blood around the brain. These cerebral venous blood clots are different from the regular blood clots that cause the large majority of ischemic strokes, as in the latter, blood clots either form inside of, or travel to, a small area of an arterial branch, causing a blockage in blood flow to a brain area, whose oxygen-deprived state is responsible for the ensuing symptoms.

Unlike most acute strokes, venous blood clots cause vague symptoms, such as headache, blurry vision, or double vision. But when the blood clots become large enough, they can cause blood to back up in the arteries and cause either a subarachnoid or an intracerebral hemorrhage.

There are certain risk factors for dural sinus thrombosys that you should be aware of, especially if you are young, pregnant, or a smoker. These and other facts about strokes due to dural sinus thrombosis are delineated in the article listed below.
