FIG 2. Case 2.
A, Right ECA in lateral view shows a DAVS in the distal transversal sinus. Note the convergence of the feeders toward a point.
B, Right occipital artery injection in oblique view shows the shunt is located only over an accessory sinus that has a "tubular hyperdensity" (arrow).
C and D, Superselective injection (C) and coil occlusion (D) of the dural sinus compartment.
E and F, Right occipital and right ICA angiograms, showing complete occlusion of the DAVS, while preserving patency of the lateral and sigmoid sinuses.
