This report describes a rare case of an arterial anomaly in the celiaco-mesenteric region, encountered in a Japanese female cadaver for dissection at the gross anatomy laboratory of Kurume University School of Medicine in 2003. The usual celiac trunk was not identified, and the left gastric artery, the splenic artery and the hepato-mesenteric trunk independently arose from the abdominal aorta. Moreover, the hepatic artery arising from the hepato-mesenteric trunk ran behind the portal vein. The classification for this type of arterial anomaly is a Type II' of Morita's classification and Type II of Higashi and Hirai's classification, not belong to the Adachi's.

Background: Typically, the celiac trunk and superior mesenteric artery branch off separately from the anterior aspect of the abdominal aorta. The celiacomesenteric trunk (CMT) is a rare variant in which those arteries share a common origin. We sought to compare the prevalence of CMT in the Caribbean with the global prevalence as calculated by a systematic review.

Understanding of variations in the course and source of abdominal arteries is crucial for any surgical intervention in the peritoneal space. Intricate surgeries of the upper abdominal region, such as hepato-biliary, pancreatic, gastric and splenic surgeries, require precise knowledge of regular anatomy and different variations related to celiac trunk and hepatic artery. In addition, information about the origin of inferior phrenic artery is important in conditions such as hepatocellular carcinoma and gastroesophageal bleeding management.

Purpose: The hepato-mesenteric trunk is an extremely rare condition in which the common hepatic artery (CHA) originates from the superior mesenteric artery (SMA). Usually, CHA passes behind the head of the pancreas. A systematic review was performed to provide guidelines for the perioperative management of patients with this anatomical variation who underwent a pancreaticoduodenectomy (PD).

Celiac trunk is the first ventral branch of the abdominal aorta. It usually terminates by giving three branches; the common hepatic artery, the left gastric artery and the splenic artery. We report a rare variation of the branching pattern of the celiac trunk.

We describe the case of a hepatic artery originating from a hepato-mesenteric trunk and traveling through the head of the pancreas, found preoperatively in a 44-year-old woman presenting two metachrone intra-pancreatic metastasis of a skin melanoma. Few cases with this anatomic variation have been found in the published literature consulted and this is the first case of duodenopancreatectomy for melanoma metastasis associated with this anatomic variant. In this patient, multidetector CT image with angiography and 3-D reconstruction demonstrated that the common hepatic artery arose from the superior mesenteric artery without any other arterial supply to the liver.
