Probably nBCA is the least utilized agent for MMA embo. Its a shame — it works well, injections are quick, and can be very safe if one knows how to use it. For example, in this case of MMA supply to the orbit, glue is an excellent choice. Not what many would think, but true
MIPS show superior orbital fissure entry site. Supply to superior rectus also
What to do — go distal to the meningolacrimal branch with a scepter C
Now inflate the scepter gently but effectively to stop reflux, and inject 2:1 Lipidol:nBCA — excellent penetration into secondary MMA branches and the anterior falcine / anterior meningeal branch in wall of the superior sagittal sinus. Scepter ensures no reflux into the orbit
Now for the petrosquamosal branch — headway duo catheterization of smaller branch achieves flow control
nBCA here — nice penetration even beyond midline — a potential collateral pathway for mma reconstitution is contralateral MMA
Post embo shows preserved meningolactrimal branch
Cast of nBCA inside convexity on DYNA CT — nice, right?
