Background. Liver transplantation is currently the most effective method to treat diseases with end-stage liver failure. Complications are most often associated with the initially severe patient condition, imperfect organ preservation methods, the surgical management per se, and immune system incompetence. The most common complications of transplantation include ischemic reperfusion injury, which occurs to some or another extent in each transplanted organ and worsens the course of the postoperative period. The process is based on complex pathophysiological mechanisms of cell damage due to ischemia and inflammation caused by reperfusion.Objective. To summarize current data on the mechanisms of the ischemic reperfusion injury development in liver transplantation and to find the ways to reduce adverse effects.Material and methods. The analysis of data from foreign and homeland experimental and clinical studies on the pathogenesis of ischemic reperfusion injury in liver transplantation has been performed. The search for literature data was carried out in international databases (PubMed/MedLine, ResearchGate, as well as in the scientific electronic library of Russia (eLibrary.RU) for the period from 2020-2024.Conclusion. The analyzed publications have provided various algorithms for the preservation of donor organs, including those using machine perfusion.
