Brain vein stent could silence pulsatile tinnitus
NCT ID NCT07515781
First seen Jun 27, 2026 · Last updated Aug 21, 2026 · Updated 1 time
Summary
This study tests a stent called VivaStent to see if it is safe and can reduce severe pulsatile tinnitus (a rhythmic whooshing sound in the ear) caused by a narrowed vein in the brain. About 15 adults with this condition will have the stent placed to widen the vein. Researchers will check for side effects and measure tinnitus improvement over 12 months.
