Research Article: Retrograde inferior vena cava perfusion reduces the risk of acute kidney injury depending on the oxygen extraction ratio. A retrospective cohort study

Date Published: 2025-04-28

Abstract:
Background: Total aortic arch replacement surgery (TARS) for Acute type A aortic dissection is associated with high incidence of postoperative acute kidney injury (AKI), at least partly due to the lower body ischemia during circulatory arrest. This study aimed to evaluate whether retrograde inferior vena cava perfusion (RIVP) reduces the risk of AKI by providing oxygenated blood to the lower body.
