Fig 1. A 43-year-old man with an incidentally discovered tentorial dural fistula.
A, Lateral view of 3D right internal carotid artery angiogram demonstrates a tentorial dural fistula mainly supplied by the tentorial artery. Additional arterial supply was by lateral clival branches, the occipital artery, and the middle meningeal artery.
B, Angiogram via microcatheter in the tentorial artery during balloon occlusion of the internal carotid artery at the level of the tentorial artery. The balloon prevents reflux, stabilizes the microcatheter, and induces flow control. From this point, glue was injected with deep penetration into the veins.
C, Follow-up angiogram 6 weeks later demonstrates complete closure of the fistula.
