Isolated Hepatic Perfusion in Combination With Ipilimumab and Nivolumab in Patients With Uveal Melanoma Metastases

The procedure is performed under general anaesthesia. The caval vein is isolated infrahepatically above the renal veins and suprahepatically between the diaphragm and the pericardium. A catheter is placed in the retrohepatic portion of the caval vein for perfusion outflow. The portal vein is clamped and the proper hepatic artery is cannulated via the gastroduodenal artery. The liver perfusion is performed at a rate of 8- 9 ml/kg/min with a target liver temperature of 40 degrees Celsius. The leakage from the system was continuously recorded using Technetium labelled albumin (Vasculosis) injected into the perfusion circuit. Melphalan (1 mg/kg bodyweight divided into two doses, given 30 minutes apart) is added to the perfusion system. The perfusion is then continued for 60 minutes, after which the perfusion was discontinued.

4 courses of ipilimumab 3mg/kg every third week
