From March 1977 to July 1979, 69 cases of angiograms of hepatocellular carcinoma were observed in Seoul National University Hospital. the findings of selective celiac and/or hepatic arteriography in total 69 cases of confirmed hepatocellular carcinoma, with clinical and laboratory findings, were analysed. The summarized results are as follows; 1. Among 69 cases of hepatoma, 62 were male and 7 were female with sex ratio of 8.9:1. Peak incidence is 5th to 7th decades (72.5%). Epigastric pain, indigestion, and palpable mass in right upper quadrant were common symptoms and sign. Laboratory findings showed elevated serum alkaline phosphatase more than 5 Bodansky unit in 75.4%. Alpha-feto protein was positive in 65.2% of all the patients. 2. All 69 cases were classified into 31 cases of massive type, 22 cases of diffuse type, and 16 cases of nodular type, in accordance with angiographic gross anatomy. The frequency of angiographic findings were hypervascularities and tumor vessels ( 00%), tumors stainings (98.5%), arteriovenous shunt (71.0%), displacement of intrahepatic arteries (66.7%), vascular lakes and channel (59.4%). Encasement of hepatic artery and portal vein regurgitation was respectively 4 cases. Tumor mass in portal vein were 6 cases and tumor mass in hepatic vein was 1 case. 3. Intraarterial infusion of 5-FU was performed in 15 hepatoma patients, and results were that angiographic improvement was demonstrated in 3 cases, no improvement in 8 cases, and incomplete infusion in 4 cases. 4. The selective celiac and/or hepatic angiograms are excellent diagnostic tools as well as therapeutic management for intraarterial infusion of anticancerous drugs.
