Participating in the trial means that the participants will undergo an experimental procedure called "venous sinus stenting" to open up the narrowing in the vein that is causing the tinnitus. This procedure requires taking two blood thinners called aspirin and Plavix. Both blood thinners will be initiated 1 week prior to the procedure and continued for 1 month after the procedure. At that time the Plavix will be stopped and aspirin will be continued for 11 more months (total of 12 months).
