Figure 2.

Patient Nr 5. Preliminary DSA during selective injection of both external carotid arteries (a, b) and vertebral arteries (c, d) shows a high flow DAVF of the vein of Galen causing a major venous outflow impairment of the cerebral circulation (not shown but evident during ICA selective injection). SQUID 12 embolic agent was injected through the distal left MMA (e) after trapping detachable distal tip of the microcatheter with coils (“pressure cooker” technique), in order to reduce proximal reflux. Unsubtracted image (f) shows SQUID 12 cast at the end of the endovascular treatment. Injection time was 30 minutes and the amount of embolic agent was 6 ml. 9–months follow-up (g, h) confirms the complete occlusion of the cDAVF.
