Highlights
Cerebral venous sinus thrombosis (CVST) is a rare form of stroke that results from thrombosis of the dural venous sinuses, which drain blood from the brain
Most cases of cerebral venous sinus thrombosis are due to hypercoagulability.[1,6,7]
Causes: Cerebral venous sinus thrombosis is more common in particular situations. 85% of patients have at least one of these risk factors.[1,8,9,10]
Summary
Cerebral venous sinus thrombosis (CVST) is a rare form of stroke that results from thrombosis (a blood clot) of the dural venous sinuses, which drain blood from the brain. Cerebral venous sinus thrombosis is not common. In cerebral venous sinus thrombosis, blood clots usually form both in the veins of the brain and the venous sinuses. The thrombosis of the veins themselves causes venous infarction This results in both vasogenic and cytotoxic cerebral edema, and leads to small petechial haemorrhage that may coalesce into large haematomas. Most cases of cerebral venous sinus thrombosis are due to hypercoagulability.[1,6,7]. Causes: Cerebral venous sinus thrombosis is more common in particular situations.
