A Case of Aortic Dissection of the Abdominal Aorta Complicated by Renal Dysfunction in Whom an Endovascular Aneurysm Repair was Implanted Successfully Using Carbon Dioxide Angiography

Abstract

Background: Endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm is a minimally invasive regimen, but iodine contrast media is necessary and can be contraindicated in cases of iodine allergia or renal dysfunction. We treated a case with EVAR using carbon dioxide (CO₂) angiography. Case: An 87-year-old man who had undergone 4 laparotomies was receiving treatment for bladder stones. He had renal dysfunction. CO₂ angiography revealed a saccular abdominal aortic aneurysm caused by an ulcer-like projection. EVAR was indicated. Since EVAR requires contrast medium, the angiography was performed using medical CO₂. Conclusion: CO₂ is useful for angiography when iodinated contrast medium cannot be used. This method could increase operable cases of EVAR.
