As noted in several other pulsatile tinnitus pages here, the relationship between venous hypertension, PT, and venous sinus stenosis continues to be defined. Some believe venous stenosis to be the long-sought cause of IH, others feel that high CSF pressure … Continue reading
Here is a more nuanced case of venous pulsatile tinnitus. Venous sinus stenosis is perhaps the most under-recognized cause of pulsatile tinnitus today. See Venous Sinus Stenosis page and Cases 1 and 2 of venous sinus stenosis and stenting for … Continue reading
The most under-recognized cause of pulsatile tinnitus is venous sinus stenosis. It is a common and usually asymptomatic / incidental finding. However, that is not always the case. Some patients develop pulse-synchronous tinnitus due to turbulent flow across the area … Continue reading
Venous sinus stenosis is the most under-recognized cause of pulsatile tinnitus. Venous sinus stenosis, particularly of the sigmoid sinus, is common and, in vast majority of cases, asymptomatic. Which is why it is usually overlooked on imaging studies. Many patients … Continue reading

Venous pulsatile tinnitus is one of the most common causes of this under-recognized disorder. The hallmark of venous tinnitus is the ability of patient to suppress the sound by ipsilateral jugular compression, which reduces flow in the entire ipsilateral transverse/sigmoid/jugular … Continue reading
A well-known association between pulsatile tinnitus and intracranial hypertension is now established. Most patients with significant IH have at least sigmoid sinus stenosis. The chicken/egg question of what begets what remains unsolved. Does high CSF pressure collapse the sinus? Or … Continue reading
As much as we talk about superselective transvenous embo, one can argue that there are many ways to skin the cat. Transarterial often ain’t pretty, and also more hazardous as a rule, but it usually works. Many superselectives are simple … Continue reading
We have come a long way in understanding of how to treat dural fistulas. This is particularly important in places like torcular, where sinus sacrifice is usually not an option, and effective transarterial embolization can be challenging. The superselective transvenous … Continue reading
Continued advances in angiographic imaging, especially flat panel DYNA variety we use, allow for tremendously better visualization. This goes hand in hand with our evolving understanding. The old ophthalmic artery page may be found here. See Diagrams and Drawings page … Continue reading
