What causes pulsatile tinnitus?

Many cases of pulsatile tinnitus can be traced to stenosis in one of the large veins in the brain, most commonly the traverse and sigmoid sinuses. The narrowing of the veins causes a disturbance in the blood flow, contributing to the whooshing sounds of pulsatile tinnitus. Recent clinicals trial for pulsatile tinnitus and pseudotumor cerebri (which can cause pulsatile tinnitus) showed that inserting a stent to widen the veins could restore healthy blood flow and eliminate the symptoms of pulsatile tinnitus.
