Abstract
The effects of arterial infusion with chemotherapy alone or in combination with hepatic artery ligation on the normal liver of the cat were studied. Early in the course of treatment catas receiving chemotherapy infusion only appeared sicker than animals in other groups. Yet only 1 of 5 cats was dead at 12 weeks. In contrast, 4 of 6 animals that had hepatic artery ligation and chemotherapy infusion, and 3 of 6 that had ligation of the hepatic artery only, died during the same period of follow‐up. Progressive liver damage after dearterialization accounted for the high mortality rate. Histologic examination of liver biopsies taken from animals in these latter groups revealed marked destruction of the parenchyma. These changes were more extensive in animals treated by a combination of hepatic artery ligation and chemotherapy infusion. To avoid the injurious effects of permanent interruption of the hepatic arterial flow on normal liver tissue an alternative method of hepatic dearterialization is currently under investigation.
