Portohepatography with an oily contrast medium.

Splenoportography was performed in 38 patients, mainly with malignant tumors and metastases, using an oily contrast medium (lipiodol U.F.). The injection was well tolerated in all cases. Visualization of the intrahepatic branches of the portal vein was much clearer than that obtained with a water-soluble medium, and the hepatograms, in particular, were much more intense.The examination is not recommended in the presence of portal hypertension but is otherwise indicated in the demonstration of liver tumors and abscesses.
