Cerebral venous thrombosis. Presse Med. 2016 Nov 2;: Authors: Ferro JM, Canhão P, Aguiar de Sousa D Abstract Cerebral venous thrombosis (CVT) has an incidence of 1.32/100,000/years in high-income countries, and higher in middle- and low-income countries. CVT is more frequent in infants and children young adults and females, especially during pregnancy/puerperium. CVT are now being diagnosed with increasing frequency because of the increased awareness and higher use of magnetic resonance imaging (MR) for investigating patients with acute and subacute headaches and new onset seizures. CVT rarely present as a stroke syndrome. Their most frequent presentations are isolated headache, intracranial hypertension syndrome, seizures, a lobar syndrome and encephalopathy. The confirmation of the diagnosis of CVT relies on the demonstration of thrombi in the cerebral veins and/or sinuses by MR/MR venography or veno CT. The more frequent risk factors/associated conditions for CVT are genetic prothrombotic conditions, antiphospholipid syndrome and other acquired prothrombotic diseases, including cancer, oral contraceptives, puerperium and pregnancy, infections and trauma. The prognosis of CVT is in general favorable, as acute death rate is below 5% and only 15% of the patients remain dependent or die. Treatment in the acute phase includes management of the associated condition, anticoagulation with either low molecular weight or unfractionated hep...
