摘　　要：Hepatic ischemia-reperfusion syndrome has been the subject of intensive study and experimentation in recent decades since it is responsible for the outcome of several clinical entities,such as major hepatic resections and liver transplantation.In addition to the organ’s post reperfusion injury,this syndrome appears to play a central role in the dysfunction of distant tissues and systems.Thus,continuous research should be directed toward finding effective therapeutic options to improve the outcome and reduce the postoperative morbidity and mortality rates.Treprostinil is a synthetic analog of prostaglandin I2,and its experimental administration has shown encouraging results.It has already been approved by the Food and Drug Administration in the United States for pulmonary arterial hypertension and has been used in liver transplantation,where preliminary encouraging results showed its safety and feasibility by using continuous intravenous administration at a dose of 5 ng/kg/min.Treprostinil improves renal and hepatic function,diminishes hepatic oxidative stress and lipid peroxidation,reduces hepatictoll-like receptor 9 and inflammation,inhibits hepatic apoptosis and restores hepatic adenosine triphosphate(ATP)levels and ATP synthases,which is necessary for functional maintenance of mitochondria.Treprostinil exhibits vasodilatory properties and antiplatelet activity and regulates proinflam-matory cytokines;therefore,it can potentially minimize ischemia-reperfusion injury.Additionally,it may have beneficial effects on cardiovascular parameters,and much current research interest is concentrated on this compound.
