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 Global Outcomes (KDIGO) guidelines. Bailout ICM was used in 80% of cases (mean 21.23 ± 14.09 mL). Postinterventional AKI occurred in 13.2% of patients, with over 70% classified as stage 1. Seven patients required new dialysis within 7 days. Multivariate analysis identified hypertension, heart failure, and coronary artery disease as independent AKI risk factors. Statin or Renin-Angiotensin-Aldosteron System (RAAS) inhibitor use and higher pre-interventional GFR were protective. AKI remains common in patients undergoing CO2-guided peripheral procedures. Further studies are needed to explore underlying mechanisms and outcomes.
