However, the initial results of liver transplantation with DCD grafts have been suboptimal due to an increased rate of complications, as well as decreased graft survival. These challenges have led to many developments in DCD donation outcome, as well as basic and translational research. In this article we review the unique characteristics of DCD donors, nuances of DCD organ procurement, the effect of prolonged warm and cold ischemia times, and discuss major studies that compared DCD to donation after brain death liver transplantation, in terms of outcomes and complications. We also review the different methods of donor treatment that has been applied to ameliorate DCD organ outcome, and we discuss the role of machine perfusion techniques in organ reconditioning. We discuss the two major perfusionmodels, namely, hypothermic machine perfusion and normothermic machine perfusion; we compare both methods, and delineate their major differences. 关 键 词：Transplant hepatology LIVER transplantation Organ DONATION Extended criteria donors DONATION AFTER cardiac death EX-VIVO LIVER PERFUSION Normothermic MACHINE PERFUSION Hypothermic MACHINE PERFUSION
