Infarction of renal tumors using isobutyl-2 cyanoacrylate and lipiodol

Percutaneous transcatheter embolization of the renal artery in clear cell carcinoma was performed in nine patients. The occlusive material used was a suspension of 1 ml of isobutyl-2-cyanoacrylate in 3 ml of Lipiodol. Six patients were operated on 2-5 days after the embolization, and in three patients the procedure was palliative. In one of the latter, follow-up arteriography 4 months later showed that the artery was still occluded. There were no complications attributed to the glue or to oil emboli in this series.
