A case of anomalous hepatomesenteric trunk and gastrosplenic trunk was found during an anatomical practice at Nippon Medical School in 2002. In 1928, Adachi1 reported the frequency of this type of anomaly to be 0.4%. The case exhibited a gastrosplenic trunk, which consisted of the splenic and the left gastric arteries and composed the celiac trunk with the common hepatic artery, arising directly from the left side of the abdominal aorta. In addition, the common hepatic and superior mesenteric arteries, arising directly from the abdominal aorta, formed a hepatomesenteric trunk. The common hepatic artery extended upward into the liver after diverging from the hepatomesenteric trunk. The abdominal arterial anomalies and unification of the abdominal arterial branches were thought to originate from rotation of the digestive organs during embryonic development. A left accessory hepatic artery and a cystic arterial anomaly were also found.
