Early allograft dysfunction (EAD), primary graft nonfunction (PNF) and biliary complications affect postoperative survival after liver transplantation (LT). Ischemia injury is one of the major factors affecting liver allograft functional recovery. Ischemia-free liver transplantation (IFLT) has obvious advantages for the recovery of allograft function and complication incidence compared with conventional procedures. However, its use is limited when the donor and the recipient are not in the same hospital and donors should be donor after brain death (DBD). We propose an approach to avoid double warm ischemic injury by implanting marginal donor liver directly by using normothermic machine perfusion (NMP) without re-cooling. Here, we report the first case of non-re-cooling implantation for marginal donor in LT. Donor liver biopsies before procurement showed 50% macrovesicular steatosis, and the recipient was a 67-year-old man with decompensated cirrhosis secondary to a 21-year hepatitis B virus (HBV) infection. The donor liver was maintained by NMP without re-cooling before implantation. The highest levels of alanine transaminase (ALT) and aspartate transaminase (AST) after surgery were 235 and 1,076 U/L, respectively, on the first postoperative day (POD). The patient was discharged within 2 weeks and showed good recovery. Thus, it is feasible to use Non-re-cooling implantation for marginal donor in LT.
