A Contrast Medium Sparing Strategy Using Automated CO2 Injection During PVI for Prevention of Major Adverse Kidney Events (MAKE)

The primary objective of the trial is to evaluate if an iodinated contrast medium sparing strategy using automated Carbon Dioxide (CO2) Injection prevents Major Adverse Kidney Events up to 90 days (MAKE90) in patients at moderately elevated risk for contrast-associated acute kidney injury (CA-AKI) undergoing infrainguinal peripheral vascular interventions (PVI).

PeriPREVENT is a prospective, multi-centre, controlled, open-label, 1:1 randomized superiority trial with two parallel groups. In the intervention group patients will undergo a routine peripheral angiographic intervention (PVI) using a maximally contrast medium sparing strategy with an automated CO2 injection system including iodinated CM as bailout option in case of insufficient image quality or patient's intolerability of CO2 angiography. The control intervention is routine PVI using iodinated contrast media (CM) as standard of care. All patients are followed up until 12 months after the PVI.
