BACKGROUND/AIMS: The evaluation of portal blood flow in hepatic mass is important for the diagnosis of hepatocellular carcinoma. We have designed a new method to easily evaluate portal blood flow in hepatic mass using ultrasonography with injection of carbon dioxide into the intrahepatic portal vein by direct puncture with a fine needle.
METHODOLOGY: We evaluated 29 masses in the liver of 20 patients ultrasonically with injection of carbon dioxide into the intrahepatic portal vein.
RESULTS: Of 29 space-occupying lesions (SOLs), 13 were found to have portal blood flow and 16 were found to have no portal flow by this method. All 15 SOLs which had no portal flow were histologically confirmed to be hepatocellular carcinoma. Of 13 SOLs with portal flow, 5 were confirmed to be hepatocellular carcinoma. For 7 of 9 SOLs in which both this method and arterial portographic computed tomography were performed, the results were in agreement.
CONCLUSIONS: Ultrasonographic evaluation of portal blood flow using transhepatic carbon dioxide injection appears to be useful for the evaluation of portal now in! mass and may aid in the diagnosis and management of mass in patients with liver disease.
