Pulsatile tinnitus is a rhythmic sound that matches your heartbeat. It is often caused by a narrowing (stenosis) in one of the venous sinuses in the brain, leading to turbulent blood flow. Treating the root cause by reopening the narrowed segment with a stent restores normal blood flow and eliminates the sound in the majority of patients.
It is a rhythmic sound that matches your heartbeat, heard in one or both ears or in the head. It is different from non-pulsatile tinnitus, which is usually not related to blood flow.
During venous sinus angiography, the pressure difference across the narrowed segment is measured:
Pressure before the stenosis (proximal)
-
Pressure after the stenosis (distal)
=
pressure gradient > 8 mmHg is considered significant.
A significant gradient confirms that the narrowing is causing the abnormal venous flow and is the source of the symptoms
A small catheter is inserted through a vein in the neck (jugular vein) or groin under local anesthesia.
A catheter is guided to the venous sinus and angiography is performed to confirm the stenosis and measure pressure.
A microguidewire is safely passed across the narrowed segment of the venous sinus.
A stent is deployed across the narrowed segment to open the sinus and restore normal blood flow.
Normal blood flow is re-established, turbulence stops, and the pulsatile sound disappears in most patients.
The Fact: The cause determines the appropriate treatment, and treating the narrowing with a stent is the safe and effective solution.
