Diagnostic accuracy of various kinds of hepatic angiography was analyzed in the resected 10 cases (15 nodules) of the primary carcinoma of the liver. By the celiac angiography, only 7 (4 cases ) out of 15 nodules (10 cases) were, detected and remaining 8 nodules were not detected. The sizes of these 8 nodules were less than 3cm in diameter and were located near the top of the liver near right diaphragm. These nodules were detected by the super selective hepatic angio graphy; proper hepatic, right hepatic, proper hepatic pharmacoangiography and proper hepatic slow infusion angiography. To detect all of the hepatoma nodules in the liver, proper hepatic or right hepatic and left hepatic angiography are principal.By the superior mesenteric arterial portography, abnormal portogram (Filling defect and stretching) were recognized in the big hepatoma which sizes were greater than 3cm in diameter. Superior mesenteric arterial portography is effective to detect the portal infiltration of the hepatoma.
