Key Points about Intracranial Venous Thrombosis
- Definition: Intracranial venous thrombosis (ICVT) occurs when a blood clot forms in the dural venous sinuses, which drain blood from the brain. This condition can lead to increased intracranial pressure and cerebral venous infarction.
- Causes: Common causes include hypercoagulable states (e.g., pregnancy, oral contraceptives, malignancy), infection, trauma, and certain autoimmune conditions like lupus.
- Symptoms: Symptoms vary depending on the location and extent of the thrombosis but often include headache, seizures, focal neurological deficits, visual disturbances, and altered consciousness.
- Diagnosis: Diagnosis is made using imaging studies like CT venography or MR venography, which can reveal the location of the thrombus and any associated brain swelling or infarction.
- Management: Initial management focuses on anticoagulation with heparin, even in the presence of haemorrhage, to prevent thrombus extension. In severe cases, thrombolysis or mechanical thrombectomy may be required.
- Complications: Without prompt treatment, complications can include cerebral oedema, venous infarction, haemorrhage, and permanent neurological deficits. Death can occur in severe cases.
