- W1559408082 abstract "Thrombosis of the dural sinus and encephalic veins (cerebral venous thrombosis, or CVT) was until recently considered a rare, often fatal disease, related to the puerperium and to infection of the central nervous system, sinuses, and mastoid. The introduction of magnetic resonance imaging (MRI) in clinical practice dramatically modified this picture. CVT became recognized with increasing frequency and its clinical spectrum has widened considerably. CVT is less frequent than other types of stroke. CVT has a rather variable clinical presentation and there is a need to perform MRI/angiography to confirm the diagnosis. Obstruct ion of the venous structures causes increased venous pressure, reduced capillary perfusion pressure and increased cerebral blood volume. Dilatation of cerebral veins and recruitment of collateral pathways may initially compensate for changes in pressure. Blood flow in veins with poor collateral flow will become slow and might contribute to extension of the thrombosis. Another effect of venous thrombosis, besides parenchymal changes, is impairment of CSF absorption which causes intracranial hypertension. Besides an acute presentation, CVT can have a more protracted subacute or chronic course. The clinical presentation of CVT varies accordingly to the presence of parenchymal lesions and with the location of the occluded sinus or vein. The chapter discusses the etiology and diagnosis of CVT, prognosis of CVT, and treatment of CVT." @default.
