[Devices for Transvenous Embolization of Dural Arteriovenous Fistulas].

When approaching an occluded sinus during transvenous embolization of dural arteriovenous fistulas, it is important to employ a combination of appropriate guiding and distal access catheters to ensure adequate support and effective navigation. When navigating a long and tortuous venous route, careful attention must be given to the backup support and lengths of the coaxial catheters and connectors. Effective embolization can be achieved by selecting coils according to the stage of the embolization procedure and using liquid embolic agents when indicated.
