Brief Summary
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.

Study Arms (2)
venous stenting
EXPERIMENTALVenous stenting associated to antiaggregation protocol: Venous stenting: venous approach can be performed via femoral, brachial or jugular puncture. Autoexpansible stent should delivered at the level of the fistulous sinus. If distal access catheter is wide enough, stent can be delivered directly through it. After partial deployment of the stent, Labbe vein's flow may be restricted. If necessary, several stents can be used in the same procedure to cover the whole length of fistulous sinus area. After stent deployment, ballon angioplasty is compulsory and must be performed using a ballon of equivalent size to the stent. The procedure ends after stent deployment and angiographic arterial post-op controls. Antiaggregation protocol: aspirin (160mg for 3 months) + clopidogrel (75mg/d 5 days before stenting and 75mg/d for 1 month after stenting) OR ticagrelor (180mg 2h before stenting and 90mg twice a day for 1 month) in case of clopidogrel platelet resistance.
