The role of venous anatomy in guiding treatment approach for dural arteriovenous fistulas of the craniocervical junction; case series & systematic review

Transarterial embolization of radicular arteriovenous fistula at the craniocervical junction

“…SAH, intramedullary hemorrhage, and myelopathy are known as the common clinical presentation [1 , 2] , and drainage patterns play an important role in these presentations. Historically, the presence of ascending venous drainage, varix of drainage vein, RAVF, and arterial feeder of ASA have been suggested significantly high-risk factors for SAH [4] , [5] , [6] , and these were also observed in our case. Also, we recognized ARSA in which the right subclavian artery arose from the descending aorta [7] .…”
