Prevalence of dural venous sinus stenosis and hypoplasia in a generalized population

Abstract

The prevalence of bilateral transverse sinus stenosis in the general population is not trivial. These data may be used as a reference for understanding the mechanistic role of stenoses in idiopathic intracranial hypertension, tinnitus, and refractory headaches.

Recommendations for the selection and treatment of patients with idiopathic intracranial hypertension for venous sinus stenting

“…Durst et al found the prevalence of unilateral transverse sinus stenosis or hypoplasia in the normal population to be 33% and the prevalence of bilateral transverse sinus stenosis to be 5% 25. Radvany et al observed in a study of 12 patients that two patients who underwent catheter venography had no pressure gradient, despite apparent transverse sinus stenosis on CTV 26.…”

The manifestation of vortical and secondary flow in the cerebral venous outflow tract: An in vivo MR velocimetry study

“…Several open and endovascular interventions have even been developed to treat anomalies of the CVOT (Ahmed et al, 2011; Eisenman, 2011; Houdart et al, 2000; Starke et al, 2015). However, anatomic variance is quite wide and lumenal irregularities such as sinus stenosis may not always be pathologic (Durst et al, 2016). Figure 1 shows the structure of the CVOT anatomy within the head.…”

Venous sinus stenting in patients without idiopathic intracranial hypertension

“…Our understanding of the pathophysiological relationship between dural venous sinus stenosis and hydrocephalus remains incomplete as such stenosis is also found in 31–39% of patients without IIH,24 25 including 15.9% of those with headache and normal ICP 26. Despite incomplete understanding of the relationship between dural venous sinus stenosis and hydrocephalus, the final common pathway of elevated venous sinus pressures and increased ICP does not appear to be limited to patients with IIH, though correcting venous outflow obstruction may not be enough to effectively treat patients with congenital hydrocephalus.…”
