[Cerebral venous thrombosis]

Abstract

Cerebral venous thrombosis shows remarkable clinical polymorphism: isolated intracranial hypertension, cerebrovascular accident or focal, subacute cerebral lesion. Magnetic resonance imaging permits easy identification of the thrombosis and its tissular consequences as well as long-term follow-up. Search for the cause should be meticulous, given the multiple possibilities, presently dominated by prothrombotic states (postpartum, haemostasis anomalies, systemic affections, haematologic diseases, birth control pill, etc.). The development of neuro-imaging is changing the classic severity of cerebral venous thrombosis. Anti-coagulant treatment is widely used, including during haemorrhagic infarction. This treatment probably contributes to improving the survival and functional prognosis.
