Transcatheter embolization of bleeding from distal branches of small arteries can be difficult. N-butyl cyanoacrylate (NBCA) was originally used as a tissue adhesive material, and recent evidence suggests that it can also be used as an embolic material. This report describes a case in which a pseudoaneurysm arising from the distal portion of a small branch of the deep femoral artery was successfully embolized with NBCA using a new technique with a microballoon catheter. Advantages of this technique include its safely, short treatment time, good control of the embolization range, absence of fragmentation, favorable polymerization dynamics, and absence of glue reflux or excessive distal spread of the glue.
