[Experimental study on embolic materials for simultaneous segmental embolization through transarterial route].
To determine suitable embolic materials for simultaneous arterioportal embolization through the arterial route, transcatheter arterial embolization (TAE) using iodized oil (Lipiodol) mixed with monomeric n-butyl-2-cyanoacrylate, with absolute ethanol, or mixed with Gelfoam powder was carried out in 14 dogs. Following TAE, the distribution of Lipiodol in hepatic artery, peribiliary plexus, and portal vein was analyzed by soft tissue x-ray radiography and en bloc silver impregnation. As a result, Lipiodol mixed with absolute ethanol, and Gelfoam powder was considered to be the most reasonable embolic materials for this purpose.
