The effect of hepatic artery ligation (HAL) after one day and one week on intrahepatic biliary system ultrastructure and ATPase activity has been studied in the present work. The main target was to answer two questions, the first is hepatic artery blood flow mandatory in maintaining the ultrastructure of intrahepatic biliary system. The second was, whether hepatic artery ligation that has been used clinically in the management of metastatic or primary.neoplasm of liver has an effect on the integrity of intrahepatic biliary system. The results showed that HAL have no effect on the ultrastructure and ATPase activity, and hence the function of biliary system. So, the use of HAL in treatment of nonrescectable liver tumors was safe on the biliary system of liver.
