The incidence of hypersensitivity reactions to iodinated contrast material (ICM) has been increasing over the last couple decades. In those with severe renal insufficiency, extreme allergies and the recent global shortage of ICM, there remains a need for alternative contrast methods for endovascular procedures. Carbon dioxide has been proven in the literature to be a valuable alternative. In this case report, we discuss a patient with a severe contrast allergy who underwent successful endovascular repair of a thoracoabdominal aortic aneurysm with the Unitary Device solely using carbon dioxide for angiography. With more experience performing CO2 angiography, vascular surgeons can limit the iodinated contrast load on patients, thus limiting the renal dysfunction associated with these procedures.
