Two anomalous cases of the hepato-mesenteric and the gastro-splenic trunks independently arising from the abdominal aorta.
This report describes two arterial anomaly cases in the celiaco-mesenteric region, which were encountered in two Japanese male cadavers in the dissecting room at Kurume University School of Medicine in 1999. In these cases, the usual celiac trunks were not identified, and the hepato-mesenteric and the gastro-splenic trunks were independently arising from the abdominal aorta. Moreover, in the first case, the common hepatic artery passed ventral side of the portal vein and divided into the hepatic proper and the gastroduodenal arteries. This type of arterial anomaly belongs to the Type V of Adachi's classification and the Type IV' of Morita's classification. In the second case, the common hepatic artery passed dorsal side of the portal vein and divided into the hepatic proper and the gastroduodenal arteries. This type of arterial anomaly belongs to the Type VI of Adachi's classification and the Type IV' of Morita's classification.
