Abstract

Twenty rats with implanted liver tumor were studied. Following baseline angiography, the hepatic artery was embolized with Gelfoam powder or ethanol (n=12) while the controls (n=8) did not undergo embolization. Postmortem Microfil perfusion was performed in all livers. Filling of tumor lakes from the portal vein was seen more often in embolized animals than in controls, indicating the potential role of the portal venous system in the supply of dearterialized hepatic tumors. We discuss the possible clinical implication of our results.
