(a) Superselective arteriography of one of the feeding arteries (arrow) before Squid injection, venous pouch (arrowhead), and Squid cast adjacent to the catheterized feeding artery (thin arrow) were seen. (b) Superselective arteriography after Squid injection revealed Squid cast in the feeding artery (arrow). (c) Squid cast is visible on the selective arteriography of the right internal iliac artery anterior trunk after arterial Squid-12 injection. Venous pouch (arrowhead) was still visible because of fine arterial feeders (arrow). (d) A 2.7 F microcatheter was positioned in the venous pouch (arrow) and dilation of the draining vein (arrowhead) was seen on venography. (e) After deployment of 17 detachable metallic coils into the venous pouch selective contrast injection showed outflow occlusion and residual space in the venous pouch. (f) Completion arteriography revealed complete embolization of the AVM nidus. (g) Follow-up arteriography revealed complete devascularization of the AVM.
