Liver Transplantation Followed by Renal Transplantation on Extracorporeal Membrane Oxygenation: A Case Report.

We report the case of a 68-year-old woman with end-stage liver disease and end-stage renal disease scheduled for simultaneous liver and kidney transplant. Intraoperatively, she became hemodynamically unstable during her liver transplant surgery, and her renal transplant had to be postponed. On the following day, she required extracorporeal membrane oxygenation and ABIOMED Impella support for managing her severe cardiovascular decompensation. At the same time, the renal transplant was conducted to use the donor kidney already allocated for this patient. The patient was successfully managed postoperatively in the cardiothoracic intensive care unit and was discharged after 2 months. This case is unique because there are no similar cases previously reported in which renal transplantation was performed with extracorporeal membrane oxygenation and Impella support following cardiogenic shock after a liver transplant.

Stratification and Risk Reduction of Perioperative Acute Kidney Injury.

Perioperative acute kidney injury (AKI) is associated with an increased morbidity and mortality. The incidence of AKI varies depending on preoperative risk factors and the surgical setting. Preoperative risk stratification is critical for informed consent and perioperative planning. Perioperative renal protection strategies are potentially invaluable in the prevention of AKI. Current advances in the development of biomarkers may offer the opportunity for early diagnosis and the implementation of therapeutic strategies. Increased awareness and concerted efforts by all perioperative physicians are needed to provide an improved outcome for surgical patients.
