What Is Cerebral Venous Thrombosis?
Cerebral venous thrombosis (CVT) is a neurological condition in which a clot in one of the blood vessels in the brain impedes the free flow of blood. Classically, CVT occurs in the dural venous sinuses which drain blood from the brain. Patients with this condition commonly develop stroke-like symptoms such as confusion, weakness, and dizziness, and they can also experience vision problems and headaches, including severe headaches of sudden onset known as thunderclap headaches. Like other neurological conditions, the prognosis improves when the patient receives treatment early.
