A method of intermittent occlusion and chemotherapy infusion of the hepatic artery

A method of intermittent occlusion of the hepatic artery and chemotherapy infusion has been developed using a catheter introduced into the hepatic artery, with interruption of the blood flow accomplished by inflation of the balloon. This method is less likely than ligation of the hepatic artery to produce massive liver necrosis, and it ensures adequate perfusion of the tumor tissue with the chemotherapeutic agents.
