Pulsatile Tinnitus Intracranial Hypertension Venous Sinus Stenosis Stenting and Follow Up

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

Pulsatile Tinnitus Venous Sinus Diverticulum Stenting

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

Pulsatile Tinnitus Venous Sinus Stenosis and Stenting

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

Pulsatile Tinnitus Venous Sinus Stenosis

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

Pulsatile Tinnitus Venous Sinus Stenting

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

Archives Sigmoid Sinus Fenestration in Pulsatile Tinnitus

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

Pulsatile Tinnitus Intracranial Hypertension Venous Stenting

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

Superficial Venous System

Superficial Cortical Venous Network An extensive network of interconnected veins running within the sulci, highly variable in size, route, and drainage pathway subserve venous egress of the cerebral convexity. These veins typically drain the cortex, u-fibers, and some underlying deep white … Continue reading
