This is also caused by the notoriously lack of effective replacement of a failing liver by a device or intensive care treatment. While various parameters of liver function and injury are well-known from clinical practice, the majority of specific tests require prolonged diagnostic time and are more difficult to assess ex situ. In addition, viability assessment of procured organs needs time, because the development of the full picture of cellular injury and the initiation of repair processes depends on metabolic active tissue and reoxygenation with full blood over several hours or days. Measuring injury during cold storage preservation is therefore unlikely to predict the viability after transplantation. In contrast, dynamic organ preservation strategies offer a great opportunity to assess organs before implantation through analysis of recirculating perfusates, bile and perfused liver tissue. Accordingly, several parameters targeting hepatocyte or cholangiocyte function or metabolism have been recently suggested as potential viability tests before organ transplantation. We summarize here a current status of respective machine perfusion tests, and report their clinical relevance. dc:creator: Rebecca Panconesi, Mauricio Flores Carvalho, Matteo Mueller, David Meierhofer, Philipp Dutkowski, Paolo Muiesan and Andrea Schlegel dcterms:created: 2021-02-07T14:09:28Z Last-Modified: 2021-02-07T14:16:27Z dcterms:modified: 2021-02-07T14:16:27Z dc:format: application/pdf; version=1.7 title: Viability Assessment in Liver Transplantation?What Is the Impact of Dynamic Organ Preservation?
