Inclusion criteria

Inclusion criteria: Current inclusion criteria as of 03/12/2025: 1. Age >18 years 2. Scheduled to undergo any revascularisation with an endovascular component 3. Estimated glomerular filtration rate 18 years 2. Undergoing any revascularisation with an endovascular component 3. Estimated glomerular filtration rate <60 ml/min/1.73m2 4. Signed informed consent

Exclusion criteria

Exclusion criteria: 1. Known allergy to iodinated contrast media 2. Individuals already on long-term dialysis at the time of screening 3. An inability to understand the languages in which the trial materials are provided.

Design outcomes

Primary

MeasureTime frame
Log serum creatinine measured from the blood sample taken at 2, 30 and 90 days (part of the standard of care) after endovascular revascularisation

Secondary

MeasureTime frame
Key secondary outcome measure: The volume of iodinated contrast medium used during endovascular revascularization measured using data recorded in the index revascularisation intervention case report form on the day of the intervention (day 0). Other secondary outcome measures: 1. Proportion of participants developing AKI within 2 days (48 hours) of procedure based on the KDIGO definition of AKI-stage 2. Proportion of participants developing Major Adverse Kidney Events (MAKE) by 90-day follow-up. A MAKE event is defined as either death, new requirement for dialysis or worsening kidney function denoted by >25% decline in estimated Glomerular Filtration Rate (eGFR). Baseline eGFR will be defined as the most recent value before the procedure. 3. Time spent as an inpatient (days) since randomisation measured using patient medical records by a 90-day follow-up 4. Pain experienced during the procedure measured using a Visual Analogue Scale (VAS) 5. Quality of Life (QoL) at 90-day follow-up measured using the EQ-5D-5L and SF-36 questionnaires 6. The proportion of revascularisation completed as planned measured using patient medical records at one timepoint 7. Number of surgical or endovascular re-interventions measured using patient medical records by the 90-day follow-up 8. Perceived acceptability, feasibility and factors that may influence the adoption of CO2 during each revascularisation by the practitioners/participants measured using the Theoretical Framework of Acceptability Questionnaire at the 90-day follow-up for patients, and post-procedure (administered within 3 days of the intervention) and cross-sectional questionnaires (administered after few months into recruitment) for practitioners. 9. Costs associated with each procedure (health economic analysis) measured using a Healthcare Resource Use questionnaire over a minimum 90-day period (end of clinical follow-up)
