[9,10] CVT causes dysfunction primarily through 2 mechanisms: thrombosis of the cerebral veins leads to localized edema of the brain and venous infarction, and thrombosis of the major sinuses causes intracranial hypertension, leading to increased venous pressure and impaired absorption of cerebrospinal fluid. The complications of CVT may be temporally divided into those unique to the acute stage and those that are associated with the chronic stage of CVT.
