A 60-year-old man presenting with intractable tinnitus and dizziness. a and b Right (a) and left (b) external carotid artery angiograms reveal dural arteriovenous fistula at the torcula, which shows numerous feeding arteries and reflux to superior sagittal sinus (asterisk). Note that left transverse sinus is occluded and right transverses-sigmoid sinus shows focal stenosis (arrow). c and d Frontal (c) and lateral (d) spot images shows the position of Scepter-C dual lumen balloon catheter at the left middle meningeal artery. Note that proximal coil-protected embolizations were done using the mixture of N-butylacrylate and contrast material two times at the right occipital artery branches. Black arrowhead indicates the distal marker and white arrowheads indicate proximal and distal balloon markers of Scepter-C. e A spot image during the Onyx injection through the Scepter-C under roadmap. f and g Non-subtracted (f) and subtracted (g) angiograms reveal complte occlusion of dural arteriovenous fistula. h Venous phase angiogram after balloon angioplasty for the stenosis show patent torcula (long arrow) and improved stenosis of right transvers-sigmoid sinus
