The value of selective celiac and hepatic angno Graphy in the diagnosis of primary hepatoma of the liver has amply been documented in the literatures. The selective angiography is useful not only for the diagnosis of primary hepatoma and its vascular anatomy but also for intraarterial injection of anticancerous durgs. The findings of selective celiac and/or hepatic arteriorgraphy in total 38 cases of confirmed hepatocellular carcinoma of the liver, with their clinical findings, were analysed. The summarized results are as follows: 1. Incidence of hepatoma is more common in male: male to female ratio is 34:4, and the peak age incidence is 5th to 7th decades (73.7%). About twothirds of the all patients had a clinical onset characterized by indefinite abdominal symotomes such as epigastric discomfort, indigestion and palpable mass in right upper quadrant. The laboratory examinations revealed elevation of serum alkaline phosphatase more than 5 Bodansky units in 73.5% of all patien s, and the alphafeto-pretein was positive in 66% of all patients. 2. The simple chest chest PA films revealed metastatic nodules in the lung of 5 cases and esophagograms demonstrated 8 cases of esophageal varices. 3. All 38 cases were hypervascular in the selective angiograms, and the angiographic gross anatomical types were 17 cases of massive type, 11 cases of diffuse type and 10 cases of nodular type. Most constant angiographic findings of the hepatocollular carcinoma was hypervascularity and tumor vessels (100%), and the other important findings were tumor stanings (96%), displacement of intrahepatic arteries (74%), arterioportal shunt (66%), vascular lakes and channel (61%) and encasement of hepatic artery (26%), in orders, The portal vein regurgitation was in 7 cases and the artery-to-hepatic vein shunt with tumor mass in hepatic vein was in one case. 4. In 28 cases of hepatoma patients, the intraarterial injection of 10mg of Mitomycin was done through the catheter after the an iographic studies. 5. The selective hepatic and/or celiac arteriographies are one of excellent diagnostic tool of hepatocellular carinoma and an essential technique for intraarterial injection of anticancerous drugs in hepatoma patients.
