In Situ Normothermic Regional Perfusion for Liver Donation From China Category III (Organ Donation After Brain Death Followed by Circulatory Death): A Single-Center Cohort Study.

Abstract

Organ donation after brain death followed by circulatory death is practiced in China. This study evaluated the application of normothermic regional perfusion to protect the liver grafts from these donors from warm ischemia in a large transplant center in China. This prospective study involved 19 liver transplants from brain death followed by circulatory death donors that were conducted between December 2014 and June 2017. We evaluated the baseline characteristics of the donors and recipients and compared outcomes of both groups. Graft and recipient survival and postoperative complications were also analyzed. Although the normothermic regional perfusion group consisted of marginal donors with prolonged warm ischemia and recipients with higher Model for End-Stage Liver Disease scores (P < .05), postoperative tests indicated no differences in liverfunction recovery in both groups. Furthermore, total bilirubin decreased significantly faster in the normothermic regional perfusion group than in the control group (P < .05). Both groups showed similar 1-year recipient survival rates. No recipients in the normothermic regional perfusion group had any biliary complications, whereas 2 recipients in the control group developed ischemic cholangiopathy and received invasive treatment during follow-up. In situ normothermic regional perfusion demonstrated a significant benefit in grafts from brain death followed by circulatory death donors and could potentially increase both the number and quality of donated organs.
