Venous Sinus Stenting

You are here

Dr. Athos Patsalides and Dr. Marc Dinkin have pioneered venous sinus stenting for both pulsatile tinnitus and idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri. What the disorders have in common is venous sinus stenosis, a narrowing of one or more of the large veins in the brain. Venous sinus stenting is designed to safely widen one of the narrowed veins, restoring good blood flow and eliminating debilitating symptoms.

(Watch a video of Dr. Patsalides explaining the clinical trial that successfully tested this procedure.)

Contact Dr. Patsalides at 212-746-2821 or atp9002@med.cornell.edu or Dr. Dinkin at 646-962-4297 or mjd2004@med.cornell.edu. for more information about stenting.

In a normal brain, there is unobstructed blood flow from the brain towards the neck (blue arrows).

This illustration shows bilateral venous sinus narrowing (red circles). As a result of the bilateral narrowing, the blood flow from the brain to the neck is compromised, contributing to intracranial hypertension and the symptoms of pseudotumor cerebri.

The venous sinus narrowing has been treated with placement of a stent. As a result the blood flow from the brain to the neck is now restored (blue arrows), relieving the increased intracranial pressure and the symptoms of pseudotumor cerebri.
