APHP Plateform of Normothermic Perfusion for Rehabilitation of Hepatic Grafts
Condition: Liver Diseases Intervention: Procedure: Liver transplantation of a graft after assessment by normothermic perfusion Sponsor: Assistance Publique - Hôpitaux de Paris Not yet recruiting
In conclusion, we established effective, robust and fast decellularization protocols for both porcine and human livers. With this protocol the duration of decellularization for whole-organ human livers has been shortened considerably. The increased pressure and flow did not damage the ECM, as major ECM components remained intact.
We present the case of a 60 year old male patient with decompensated liver failure, and critical CAD, who received successful combined off ‐pump coronary bypass grafting without heparin and LT using ex vivo normothermic liver perfusion machine. This approach represents a novel strategy to offer LT to this very selective group of patients.
CONCLUSIONS: Mouse livers showed progressive damage to structure and function during cold storage, with mitochondrial damage perhaps showing the earliest damage. PMID: 31724923 [PubMed - as supplied by publisher]

Conclusions: Assessment of flavin, a marker of mitochondrial complex I injury, in the perfusate provides a fast prediction of liver graft function and loss during ex situ MP before implantation. This finding may have high clinical relevance, as liver grafts from extended DBD or DCD donors carry considerable risks for recipients. On-line estimation of outcome before implantation would therefore substantially increase safe utilization of liver grafts.
Objective: The aim of this study was to evaluate sequential hypothermic and normothermic machine perfusion (NMP) as a tool to resuscitate and assess viability of initially declined donor livers to enable safe transplantation. Summary Background Data: Machine perfusion is increasingly used to resuscitate and test the function of donor livers. Although (dual) hypothermic oxygenated machine perfusion ([D]HOPE) resuscitates livers after cold storage, NMP enables assessment of hepatobiliary function. Methods: In a prospective clinical trial, nationwide declined livers were subjected to ex situ NMP (viability assessment ...
This study evaluated the application of normothermic regional perfusion to protect the liver grafts from these donors from warm ischemia in a large transplant center in China. MATERIALS AND METHODS: This prospective study involved 19 liver transplants from brain death followed by circulatory death donors that were conducted between December 2014 and June 2017. We evaluated the baseline characteristics of the donors and recipients and compared outcomes of both groups. Graft and recipient survival and postoperative complications were also analyzed. RESULTS: Although the normothermic regional perfusion group consist...
