Salvage of an Octogenarian Liver Graft Using Normothermic Perfusion: A Case Report

Liver transplantation with very old donors is safe, but is associated with an increased incidence of ischemic-type biliary lesions and delayed graft function. Normothermic machine perfusion (NMP) is a novel technique for preservation of liver grafts and has the potential to reduce ischemia-reperfusion injury. A case is reported here of a liver transplantation (LT) with a graft from an 83-year-old brain-dead donor. Procurement was with dual perfusion and en bloc, modified fast technique. Donor kidneys were not transplanted due to severe atherosclerosis and poor perfusion. The liver was shipped to the transplantation center and underwent NMP with a blood-based perfusate. During machine perfusion lactates decreased, vascular flow was stable, and bile production restored, and the graft was considered suitable for transplantation. The postoperative course was uneventful and 4 months after surgery the patient is in good clinical condition with normal liver function. To date, few LTs have been performed with NMP in humans, but its preliminary results are promising. NMP allows functional evaluation of the graft and possibly reduction of post-transplantation complications when extended-criteria donor grafts are used.
