Endovascular repair of thoracoabdominal aortic aneurysms (TAAAs) using a branched stent graft is a technically challenging procedure. A 64-year-old man with multiple medical problems, including severe renal impairment, is presented with a ruptured type IV TAAA. He underwent emergency repair using an off-the-shelf branched stent graft and carbon dioxide as the exclusive contrast agent.
