Taking the Temperature on Machine Perfusion

摘要

Purpose of Review Advances in machine perfusion technology have significantly improved organ utilization. However, consensus regarding the best dynamic preservation modality remains elusive. In this report, we evaluate recent results of clinical studies for different perfusion modalities and review new avenues of basic science aimed at organ rehabilitation. Recent Findings Randomized clinical trials of normothermic and hypothermic perfusion for liver preservation have demonstrated excellent patient and graft survival. Additional strategies that combine multiple preservation modalities show promise in maximizing utilization of severely injured grafts. Studies of machine perfusion with adjunct therapeutics for organ rehabilitation are being actively explored in the pre-clinical setting with potential for rapid translation into clinical trials. As machine perfusion becomes more widely incorporated into routine clinical use, graft utilization and transplant outcomes are likely to further improve. Logistics considerations that expand the use of this technology while minimizing costs will foster its broader adoption. Therapeutic strategies that aim to rehabilitate untransplantable grafts have the potential to greatly expand the pool of donor organs for transplantation, thereby easing the organ shortage.
