Cyanoacrylates in transcatheter renal embolization.

Isobutyl-2-cyanoacrylate and N-butyl-2-cyanoacrylate were used in experimental trans-catheter embolization of rat kidneys and in two patients as preoperative embolization of renal carcinoma. The agents produced an efficient and lasting embolization, with no evident complication; however, their usage is difficult and an appropriate dosage is also difficult.
