Instant selective arterial occlusion with isobutyl 2-cyanoacrylate

Isobutyl 2-cyanoacrylate (IBC) delivered selectively in small doses produced immediate occlusion of the injected arteries in dogs without significant undesired sequelae. In one patient, pelvic hemorrhage was promptly stopped by a similar technique. In another patient, who was on chronic renal dialysis and judged too ill for nephrectomy, IBC occluded both renal arteries and terminated a life-threatening renal protein loss.
