Objective. To determine with the use of color Doppler sonography whether bile duct tumor thrombi had detectable vasculature in hepatocellular carcinoma. Methods. Among 491 patients with tissue-proven hepatocellular carcinoma, 9 (1.8%) had bile duct tumor thrombi. All 9 patients had spectral Doppler sonography guided by color Doppler sonography (3.75-MHz convex probe). Results. All 9 patients had dilated bile ducts with isoechoic thrombi. Eight patients had tumors infiltrating into and obstructing adjacent major bile ducts. The other patient had common hepatic duct tumor emboli that were not adjacent to primary tumors. Color signals were detectable within bile duct tumor thrombi in 7 patients. All of them had pulsatile waveforms on spectral analyses. Conclusions. Bile duct tumor thrombosis with obstructive jaundice was a rare complication of hepatocellular carcinoma. A detectable color signal with pulsatile waveforms was shown in most cases by color Doppler sonography with spectral analyses.

Key Words: bile duct tumor thrombi • color Doppler sonography • hepatocellular carcinoma

Abbreviations: CDS, color Doppler sonography • ERC, endoscopic retrograde cholangiography • HCC, hepatocellular carcinoma • MR, magnetic resonance • PTC, percutaneous transhepatic cholangiography
