Endovascular Management of Cerebral Venous Sinus Thrombosis

Abstract

dural sinus or cerebral venous thrombosis (CVT) accounts for 0.5% to 1% of all strokes, mostly affecting young individuals and women of child bearing age. Patients with CVT commonly present with headache, although some develop a focal neurological deficit, decreased level of consciousness, seizures, or intracranial hypertension without focal neurological signs[24,27,28]. Uncommonly, an insidious onset may create a diagnostic challenge. A pro thrombotic factor or a direct cause is identified in approximately two thirds of patients with sinus thrombosis. The diagnosis is usually made by venographic studies with CT (CTV) or MRI (MRV) to demonstrate obstruction of the venous sinuses or cerebral veins by thrombus[69,88]. Management of CVT includes treatment of the underlying condition; symptomatic treatment; the prevention or treatment of complications of increased intracranial pressure, ICH, or venous infarction; and typically, anticoagulation therapy.
