Venous Sinus Stenosis

What is a Venous Sinus Stenosis?

Venous Sinus Stenosis is a type of cerebral venous system disease that obstructs venous blood outflow. Studies have shown that it may cause increased intravenous pressure, reduced regional blood flow, thus resulting in intractable headaches, and progressive visual loss. This is also known as idiopathic intracranial hypertension (IIH).

What is a Venous Sinus Stenting?

Venous Sinus Stenting is a minimally invasive procedure for the treatment of Venous Sinus Stenosis. As the name implies, it involves placement of a metallic mesh in the shape of a tube/stent in narrowed vein to expand the vein and resolve the narrowing. This result in improve in the pressure inside the brain and improve the headache and visual symptoms.

Symptoms

Patients with intracranial hypertension because of narrowed veins may suffer from severe headaches and blurred vision, or vision loss.

Procedures

Venous Sinus Stenting: The venous sinus stenosis has been treated with placement of a stent, a placement of metallic mesh in the shape of a tube in the narrowed vein. After the stenting is done, the blood flow from the brain to the neck is restored, leading to normalized intracranial pressure and improvement of the symptoms of IIH.
