The goal of this randomized trial to assess the angiographic efficacy of venous stenting in dural arteriovenous fistulae (DAVF) via improvment on Cognard's Classification as compared to no intervention at 6 months Participants belonging to experimental group will be treated using venous stenting. DAVF will be assessed by angiography at 6 months follow-up. Participants belonging to control group will be followed accordingly to standard of care (no treatment). After 6 months, control group patients can be treated by any means accordinlgly to standard of care.
