From: Dural carotid-cavernous fistulas: our experience with endovascular management
DSA images in AP (a) and lateral (b) projections show type C indirect CCF with fistulous connection at foramen spinosum level (arrow). c Super-selective cannulation with tip of microcatheter at fistula site. d Post coiling DSA shows residual filling from a thin branch of the right occipital artery (arrow in d). e Super-selective cannulation of the tiny feeder with another microcatheter (arrow in e). Post embolization DSA images in AP (f) and lateral (g) projections show non-filling of the fistula. h DSA image showing normal opacification of right ICA branches
