- Fig 1.
A, Right sigmoid sinus DAVF receives arterial supply from branches of the right occipital, posterior auricular, and middle meningeal arteries as demonstrated on the pre-embolization DSA. B, Posttreatment unsubtracted single-shot image demonstrates the PHIL cast. C, Control run confirms complete angiographic occlusion of the DAVF.
- Fig 2.
A and B, Initial DSA showing a high-grade right parietal DAVF supplied by a markedly tortuous petrosquamal branch of the right middle meningeal artery. C, PHIL injection through the Scepter XC balloon (MicroVention) in the proximal middle meningeal artery demonstrates good penetration of the DAVF. D, Unsubtracted image showing the PHIL cast in the draining vein, middle meningeal artery, and other arterial feeders filled in a retrograde manner.
