What is Venous Sinus Thrombosis?

The venous system is comprised of deep and superficial cortical veins that drain into larger channels called venous sinuses. These in turn drain into the jugular venous system of the neck. In certain circumstances, blood within these channels may coagulate i.e. thrombose and obstruct normal venous flow. Resultant congestion and cerebral swelling cause headache, seizures, ICH, stroke, and in some cases death.

Venous sinus thrombosis occurs in patients with blood disorders, in the dehydrated and is a complication of pregnancy. Treatment may include hydration, anti-seizure medications, blood thinners and in some cases endovascular lysis of the thrombus.
