We have long advocated the usefulness, accuracy and safety of carbon dioxide angiogrphy for patients with iodine allergy and renal dysfunction. In addition to its utility, no specialized apparatus is necessary for carbon dioxide angiography. Carbon dioxide as a contrast material has been adopted by consensus for use in endovascular revascularization. Here we report 4 cases of endovascular revascularization using carbon dioxide angiography. Two of the four patients had an iodine allergy, one had renal dysfunction, and the remaining one was complicated by diabetes mellitus. All patients exhibited intermittent claudication and were treated for iliac arterial stenotic lesions with percutaneous angioplasty and sequential endovascular stenting using carbon dioxide gas as a negative contrast material. All cases demonstrated improvement of the chief complaint. There were no direct or indirect complications of carbon dioxide angiography and endovascular intervention after the procedures. All 4 patients were discharged without event within 1 week after the endovascular intervention. Carbon dioxide is useful not only as an angiographic contrast material but also for endovascular intervention in patients with iodine allergy or renal dysfunction.
