Overview

Systematic review identifies outcomes of zero-iodine contrast EVAR in 1625 patients, suggesting CO2 can mitigate AKI risks.

Key Points

  • Using carbon dioxide for endovascular aneurysm repair shows potential to limit acute kidney injury, particularly in at-risk patients.
  • The systematic review analyzed 16 studies indicating that 510 patients underwent EVAR using CO2 exclusively.
  • Findings suggest that CO2 can replace iodinated contrast medium in endovascular procedures under specific technical precautions.
  • Limitations in CO2's physicochemical properties must be considered despite its advantages in reducing contrast use.
