This report describes anomalous cases having the so-called gastro-lienal and the hepato-mesenteric trunks instead of the celiac and superior mesenteric arteries. These anomalous cases were divided into 4 types and 6 classes according to difference of running form of the hepatic artery as follows. Type I: This hepatic artery arose from an unusual hepato-mesenteric trunk off the aorta immediately inferior to the gastro-lienal trunk. This artery ascended behind the portal vein and splenic vein, passed around in front of the left side of the portal vein, and arrived in the liver. Type II: This hepatic artery arose from an unusual hepato-mesenteric trunk off the aorta immediately inferior to the gastro-lienal trunk. This hepatic artery ascended behind the portal vein, passed around front from the right side of the portal vein, and arrived in the liver. Type III: This hepatic artery arose from an unusual hepato-mesenteric trunk off the aorta immediately inferior to the gastrolienal trunk. This hepatic artery of III-P ascended between the portal vein and pancreas, III-A ascended in front of the pancreas. Type IV: This hepatic artery arose from an unusual hepato-mesenteric trunk off the aorta immediately inferior to the gastro-lienal trunk. This type of hepatic artery ascended behind the superior mesenteric vein, passed around in front from the right side of the portal vein, and arrived in the liver. This hepatic artery of IV-P ascended behind pancreas, IV-A ascended in front of the pancreas.(ABSTRACT TRUNCATED AT 250 WORDS)
