摘要

Normothermic machine perfusion (NMP) has revolutionized liver transplantation by preserving donor livers at physiological temperatures with continuous oxygen and nutrients, reducing ischemia-reperfusion injury and enabling real-time organ function assessment. Traditional static cold storage (SCS) has limitations, particularly for marginal or extended criteria donor grafts, leading to higher discard rates. NMP expands the donor pool, improves outcomes, and facilitates predictable surgical scheduling. The “Back to Base” NMP model addresses logistical challenges by transporting livers in cold preservation solution to recipient hospitals, where they are rewarmed and perfused before implantation. This hybrid approach retains NMP benefits while simplifying logistics. Clinical experience shows that Back to Base NMP is safe and effective, with low biliary complication rates and improved graft utilization. The model also enables daytime transplant operations, improving provider well-being and operating room efficiency. Despite cost and learning curve challenges, Back to Base NMP offers a practical pathway to enhance liver transplantation outcomes.
