- FIG 1.
Internal carotid angiogram (lateral view) showed supply to the tumor from the enlarged MHT (A). After the CHIKAI X10 microguidewire was inserted into the MHT, Scepter C balloon catheter was inflated to fix the CHIKAI X10 to the ICA wall to prevent it from deviating into the distal ICA (B). The Scepter C balloon catheter was left dilated, and the tip of the DeFrictor nano microcatheter was advanced to the MHT origin. We then carefully inserted the CHIKAI X10 to the depth of the MHT (C). Superselective angiography via the DeFricter nano (white arrow) shows fluoro marker located 5 mm proximal to the tip of microcatheter. The catheter tip was non-braded for 5 mm from the tip to provide flexibility (D). Both the BGC (white arrow) and balloon catheter were inflated to prevent the distal migration of injected glue into the ICA (E). Twenty-five percent n-BCA was injected for feeder occlusion (F).

Adult patient with petroclival meningioma on gadolinium (Gd)-T1WI (A). Right common carotid angiogram (lateral view) showed supply to the tumor from the enlarged MHT (B). Both the tentorial artery and the dorsal meningeal artery were feeding vessels (C). A total of 12.5% n-BCA penetrated into the dural attachment of the tumor (arrowheads) via the dorsal meningeal artery (D and E). Postprocedural angiogram showed a partial obliteration of the feeding vessels (F). Postprocedural diffusion-weighted image showed no evidence of intratumoral ischemia and cerebral infarction (G). Postoperative Gd-T1WI showed a partial removal of the tumor (H). The 9-month follow-up Gd-T1WI showed a small recurrence on the wall of the right cavernous sinus (I).
