Relationship between dural arteriovenous fistulas and cerebral venous thrombosis

Takeaway

  • Dural arteriovenous fistulas (dAVF) have a 2.4% prevalence, most often diagnosed simultaneously with or prior to cerebral venous thrombosis (CVT); patients with CVT and dAVF carry distinct characteristics, and dAVF presence does not result in poorer outcomes.

Why this matters

  • Presence of simultaneous CVT and dAVFs has been reported, but large cohort studies are lacking, and the clinical outcomes associated with dAVFs have not been studied in people with CVT.

  • Results from this study may have screening implications, as they support increased awareness of dAVF symptoms in patients with CVT, as the conditions appear to be related.
