Isobutyl-2-cyanoacrylate (IBC) is an acrylic monomer which polymerizes quickly in contact with blood. It has rarely been used as an embolic material and never in embolization of renal cell carcinoma. IBC was used in experimental transcatheter embolization of rat kidneys and in 2 clinical cases of preoperative embolization of renal cell carcinoma. IBC is a substance which can produce a very efficient and lasting embolization; no significant complication was observed.
