[Renal cancer embolization with isobutyl-2-cyanoacrylate. Experimental study and first clinical applications (author's transl)].

Isobutyl-2-cyanoacrylate (IBC) is an acrylic monomer which quickly polymerizes in contact with blood. It has been rarely used as an embolic material and never in embolization of renal cancer. The authors report their experience on the use of this substance as embolic material, based on an experimental study in the rat and on two human cases of renal cancer, where a preoperative transcatheter embolization was performed. IBC revealed as a substance which can produce a very efficient and lasting embolization. No complications were observed.
