Analysis of Tissue and Effluent Damage Associated Molecular Patterns Following Hypothermic Oxygenated Machine Perfusion vs Static Cold Storage in Liver Transplantation
G. G. Panayotova, Y. Qin, S. Simonishvili, T. Ayorinde, F. Paterno, L. Brown, A. Amin, K. E. Lunsford, J. V. Guarrera
Transplant Surgery, Rutgers New Jersey Medical School, Newark, NJ
*Purpose: Hypothermic Oxygenated Machine Perfusion (HMP-O2) results in decreased ischemia/reperfusion injury (IRI) after liver transplantation; however, the molecular pathways of protection are largely unexplored. In…
