Venous sinus stenting to treat intractable pulsatile tinnitus caused by venous sinus stenosis

Clinical Trial Details

There have been few published studies that examine the efficacy and safety of endovascular treatments on patients with pulsatile tinnitus with venous stenosis. Despite the limited experience with venous sinus stenting to treat pulsatile tinnitus, preliminary results show that venous sinus stenting could represent a viable alternative for refractory pulsatile tinnitus patients with venous sinus stenosis. The purpose of our study is to evaluate the safety and efficacy of this procedure in a controlled fashion, using strict inclusion and exclusion criteria, and long-term clinical and imaging follow-up. The investigators hope to provide robust data regarding the safety and efficacy of venous sinus stenting for patients with pulsatile tinnitus.

Venous sinus stenting is the experimental procedure being tested in this protocol and consists of placing a stent into the narrowed veins of the brain. Under general anesthesia, a catheter will be inserted through a vein the upper part of the leg (groin area) and guided through the veins all the way to neck and the head. Then, a balloon will be advanced through the catheter and positioned across the stenosis. The balloon will be carefully inflated for a few seconds. This process is called angioplasty and will partially re-open the narrowing, making placement of the stent easier. The balloon will be removed and then the stent will be advanced through the catheter in neck across the stenosis and carefully deployed. After the procedure, the participants will stay in the intensive care unit for 24 hours for observation.
