Dural Sinus Thrombosis
Dural sinus thrombosis is clotting in the veins that drain blood from the brain.
When to get help quickly: This needs urgent hospital assessment, especially if there is severe headache with vomiting, seizures, confusion, weakness, or reduced consciousness.
Common symptoms
Symptoms may include severe headache, vomiting, blurred vision, seizures, confusion, weakness, or symptoms that look like a stroke.
When imaging helps
Imaging helps confirm whether a clot is blocking the brain’s venous drainage and shows how extensive it is or whether there are complications such as swelling or bleeding.
What radiology does
CT venography or MR venography is often used to confirm the clot and assess how much of the venous system is involved.
What usually happens next
Treatment usually includes anticoagulation and management of the underlying trigger or complication.
