简要总结
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).
详细描述
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.

研究组 & 干预措施
Standard angiography using iodinated Contrast Medium (CM)
For patients randomised in the control group, a planned infrainguinal peripheral vascular intervention (PVI, not subject to the trial) will be performed with iso-osmolar or low-osmolar iodinated CM as contrast agent.
The trial sites may use iodinated CM as defined per local routine. In line with current recommendations , the use of high-osmolar CM will be prohibited in the trial.
干预措施: Iodinated Contrast Media (ICM) (Drug)
Contrast medium sparing strategy using CO2 injection as contrast agent, bailout option iodinated CM
For patients randomised in the intervention group, a planned infrainguinal peripheral vascular intervention (PVI, not subject to the trial) will be performed with CO2 as contrast agent.
For the CO2 injection the Angiodroid® Injector will be used according to the recent user manual. The use of the Angiodroid® system allows a fully automatic injection with digital control. Automatic CO2 injection enhances patient tolerability as the gas injection is performed in a less explosive, more controlled manner.
Iodinated CM (as described in the above section) is used as bailout option in case of inadequate image quality or intraprocedural intolerance of CO2 angiography by the patient. The reasons for use and the amount of CM must be carefully recorded.
