Hi,
For entire year, every second of the day I heard whooshing in my ear to my heart beat. Found a neurosurgeon in NYC who did an MRV & MRA. Found lots of vascular congestion due to the fact my jugular had been sutured closed due to complications from a procedure years ago. Also indicated what appeared to be the fistula. Went back for angiogram of head to fully confirm. The morning of the angiogram the whooshing stoped and the angiogram indicated the jugular had opened up and the fistula was gone ( spontaneous regression). Hope that helps. Try to find a neurosurgeon that is familiar with fistulas and the repair. Hope that helps!
