Abstract

A basic requirement for arterial chemotherapy of liver tumors is complete catheter perfusion of the liver. In cases with atypical anatomy of the hepatic artery, it is frequently impossible to obtain this goal by means of a single catheter. In a patient with a right replaced hepatic artery, the aberrant vessel was ligated and the left hepatic artery was perfused through a catheter inserted into the gastroduodenal artery. Perfusion scans performed through the catheter 14 and 135 days after arterial ligation showed a fall in the arterial flow to the right liver (right/left ratio 0.43 and 0.60). In contrast, a nearly complete perfusion of the liver (0.91 right/left ratio) was obtained 28 days after ligation, when the perfusion scan was performed immediately after catheter infusion of 90,000,000 degradable starch microspheres (DSM: diameter = 40 m). DSM administration is supposed to increase back pressure in the lobe receiving native circulation, thus activating intrahepatic collateral flow to the ischemic lobe. As regards regional treatment of liver tumors, obvious conclusions are to be drawn.
