Acute Kidney Injury After Peripheral Interventions Using Carbon Dioxide Angiography-Risk Factors Beyond Iodinated Contrast Media.

ABSTRACT: Contrast-associated acute kidney injury (CA-AKI) is a known complication of endovascular procedures using an iodinated contrast medium (ICM), especially in patients with peripheral artery disease (PAD) and chronic kidney disease (CKD). This retrospective study evaluated the incidence and risk factors of AKI in patients with PAD and CKD undergoing diagnostic angiography or endovascular intervention using carbon dioxide (CO₂) as the primary contrast medium, with optional bailout ICM use. We included 340 patients who underwent peripheral angiography or intervention between September 2014 and December 2020. CO₂ was used as the primary contrast medium for all patients, as the majority were classified with advanced CKD stages 3-5 according to the Kidney Disease: Improving G
