N-butyl cyanoacrylate, one of embolic materials, is usually used as a mixture with Lipiodol (N-butyl cyanoacrylate–Lipiodol mixture). N-butyl cyanoacrylate–Lipiodol–Iopamidol was developed by adding a nonionic iodine contrast agent (Iopamiron) to N-butyl cyanoacrylate–Lipiodol mixture. N-butyl cyanoacrylate–Lipiodol–Iopamidol has lower adhesiveness than N-butyl cyanoacrylate–Lipiodol mixture and the ability to form a single large droplet. We report the case of a 63-year-old man with a ruptured splenic artery aneurysm treated by transcatheter arterial embolization using N-butyl cyanoacrylate–Lipiodol–Iopamidol. He was referred to the emergency room because of sudden onset of upper abdominal pain. A diagnosis was established using contrast-enhanced computed tomography and angiography. Emergency transcatheter arterial embolization was performed, and the ruptured splenic artery aneurysm was successfully embolized using a combination of coil framing and N-butyl cyanoacrylate–Lipiodol–Iopamidol packing. This case demonstrates the usefulness of a combination of coil framing and N-butyl cyanoacrylate–Lipiodol–Iopamdol packing for the embolization of aneurysms.
