Cerebral Venous Sinus Thrombosis
A cerebral venous sinus thrombosis (CVST) occurs when a blood clot forms in the dural venous sinuses, which drain blood from the brain.
Symptoms may include headache, abnormal vision, seizures, and any of the symptoms of stroke such as weakness of the face and limbs on one side of the body.
The diagnosis is usually made by using computed tomography (CT) scan with contrast or magnetic resonance imaging (MRI) with MR venogram to demonstrate obstruction of the venous sinuses with a blood clot. An eye exam may be performed to see if there appears to be increased pressure on the brain. Blood tests looking for a reason for blood clot formation are performed.
Typically blood thinners are given for a few months until the body has had a chance to reabsorb the blood clot.
