Venous Stroke: Be Aware Cerebral venous sinus thrombosis CVST is a rare condition where a blood clot forms in the brain’s dural venous sinuses, blocking normal blood drainage and increasing intracranial pressure. Causes & Risk Factors: * Prothrombotic states: Genetic (e.g., Factor V Leiden) or acquired (e.g., pregnancy, oral contraceptives). * Infections: Sinusitis, mastoiditis. * Systemic diseases: Lupus, inflammatory bowel disease. * Trauma or surgery: Head injuries affecting venous sinuses. *

Epidural Venous Sinuses. Dural venous sinuses are venous channels located intracranially between the two layers of the dura mater (endosteal layer and meningeal layer) and can be conceptualised as trapped epidural veins. Unlike other veins in the body, they run alone and not parallel to arteries. | Dr. Najeeb
