Analysis of early hepatic artery thrombosis after liver transplantation

Hepatic artery thrombosis (HAT) is one of the deadliest complications after orthotopic liver transplantation (OLT). This study aimed to identify risk factors and summarize the experience of HAT management after OLT.

Does ischemia free liver procurement under normothermic perfusion benefit the outcome of liver transplantation

Background In contrast to conventional static cold preservation, normothermic machine perfusion (NMP) provides a beneficial alternative preservation of donor livers. However, the liver still suffered cold ischemic injury before attaching to the perfusion device. Material/Methods To prevent cold ischemic injury during procurement, we describe a novel procedure called ischemia-free liver procurement (IFLP) under NMP. Two liver grafts were procured from brain death donor under NMP and underwent 2-hour ex vivo NMP followed by 3 and 6 hours of static cold preservation. From procurement to post-transplantation course, evidence was collected to prove that IFLP is safe and benefits recipients. Results The post-transplantation course was uneventful, and the liver function tests and histological study revealed minimal hepatocyte and biliary epithelium injury during the preservation. Conclusions This preliminary experience demonstrates the clinical feasibility and safety of IFLP under NMP which offering opportunities to increase the number of donor livers and to improve the organ function.
