Nineteen consecutive patients with malignant hilar obstruction were imaged
with angiography, CT portography, and ultrasonography with color and
spectral Doppler technique; all had surgical pathologic correlation. At
surgery, 12 of 19 patients (63%) were found to have portal vein
involvement; 15 of 19 (79%) had parenchymal invasion; and 11 of 19 (58%)
had lobar atrophy. Level of biliary obstruction was determined in seven of
19 patients (37%) without drainage catheters. No difference was found
between ultrasonography and angiography with CT portography for diagnosis
of atrophy, level of bile duct obstruction, hepatic involvement, or venous
invasion. Extrahepatic metastases in nine of 19 patients (47%) were poorly
predicted by both CT portography and ultrasonography.
