Since 1973, 12 patients in the Cambridge-King's College Hospital liver transplant programme have received livers from donors dying in hospitals considerable distances from the transplant centre in Cambridge. The method of preservation used to transport these livers from 35 to 110 miles was flush perfusion with plasma protein fraction and hypothermic storage in ice. The ischaemia times ranged from 2 hr and 42 min to 4 hr and 22 min. All of the recipients had good or excellent postoperative function of the grafts and 6 of the 12 recipients are alive, the longest survival being 29 months. The preservation technique is simple and easily portable and has given reliable 4-hr preservation of the human liver.
