Carbon Dioxide Angiography Guided Endovascular Aortic Repair for Aortoiliac Aneurysm in Patients with Renal Insufficiency

Abstract

Endovascular aortic repair (EVAR) is often selected as a first optional treatment of aortoiliac aneurysm. Some cases have chronic kidney disease (CKD) as comorbidity, which is the risk for contrast induced nephropathy (CIN). Carbon dioxide angiography (CO₂ angiography) is helpful to reduce the dose of iodine contrast medium and prevent CIN in EVAR for such patients. This description focuses on the view of CIN, CO₂ angiography and CO₂-guided EVAR in our CKD cases.
