Prevalence of Venous Sinus Stenosis in Spontaneous Cerebrospinal Fluid Leak and the Role for Venous Sinus Stenting: A Systematic Review and Meta-Analysis.

ABSTRACT:

Background

Given the association between spontaneous cerebrospinal fluid (sCSF) leak and idiopathic intracranial hypertension (IIH), and the association of IIH and venous sinus stenosis (VSS), we sought to determine the prevalence of VSS in sCSF leak and the role of venous sinus stenting for sCSF leak.

Methods

A protocol was registered in PROSPERO [CRD42024568270]. A search was conducted in four electronic databases: Medline (Ovid), Embase, CINAHL, Web of Science, and Cochrane CENTRAL. Two reviewers independently screened citations and extracted data. Methodological quality was assessed using the Joanna Briggs Institute's critical appraisal tool. Data were pooled using a random effects model to calculate overall prevalence and relative risk (RR).
