Cirrhotic livers obtained from eight patients who underwent orthotopic liver transplantation were perfused through the portal vein and hepatic artery in a closed recycling system for periods ranging from 2 to 7 hr. An average perfusion flow of 451 ml/min was used, with about 80% coming from the portal vein and 20% from the hepatic artery. The livers appeared to remain viable as assessed by gross appearance, stable portal vein and hepatic artery pressures, oxygen consumption and bile prodúction. The extraction ratio of indocyanine green by the perfused livers averaged 0.098 (range = 0.023 to 0.168); that of propranolol averaged 0.445 (range = 0.126 to 0.813). Using the multipleindicator dilution‐curve method, shunts >15 μm in diameter were demonstrated between the portal and hepatic veins in six of eight cases, whereas shunts from the hepatic artery to the hepatic veins were absent. Perfusion of human livers obtained during hepatic transplantation is a fairly simple procedure that will allow researchers to gain new insights into cirrhosis in humans. (H EPATOLOGY 1990;12:257–263).
