The portal vein system was clearly visualized in superior mesenteric arterial portography using prostaglandin E1. Angiographic examination was performed in 68 patients with various liver diseases during the 2 year period from 1980 to 1981. Twenty microgram of prostaglandin E1 was injected into the superior mesenteric artery 30 seconds before injection of 60 ml of contrast medium. The main portal vein was visualized in all of 68 cases. A high rate of success for visualization of the intrahepatic portal vein system by prostaglandin E1 was achieved. The first branches of the intrahepatic portal vein were visualized in 100% of the cases, the second branches in 82%, the third branches in 44%, and the fourth branches in 4% in the right portal vein system. In the left portal vein system, the first branches were visualized in 87%, the second branches in 41%, and the third branches in 3% of the cases. The intrahepatic portal vein system was more clearly visualized in females than in males (P less than 0.05). This procedure is simple, safe and useful for clear visualization of the portal vein system.
