The celiac trunk is the first ventral branch of the abdominal aorta and is the major blood supply to the supracolic abdominal compartment. Usually, three branches arise from the celiac trunk to supply this region, the splenic, the common hepatic and the left gastric arteries. During a routine dissection in the anatomy laboratory an extraordinary anatomical variation of the celiac trunk and its branches is found. The present case correspond of a celiac trunk, which gave off six branches. It gave off three classical branches, that is left gastric, splenic and common hepatic arteries. Beside these three branches, the right and left inferior phrenic arteries, and the superior posterior pancreaticoduodenal artery arose from the celiac axis. These anatomical variations were accompanied by a right gastric artery arising from the grastroduodenal artery instead of the common hepatic artery as describe in textbooks. During normal development, both dorsal aortas give rise to many ventral segmental (omphalomesenteric) arteries. The ventral segmental arteries regress shortly after fusion of dorsal aortas. The dorsal aorta gives off segmental branches to the digestive tube (ventral splanchnic arteries), the mesonepheric ridge (lateral splanchnic arteries), and intersegmental branches to the body wall (somatic arteries). Anatomical variations of the coeliac trunk are due to developmental changes in the ventral segmental arteries. These ventral segmental arteries supply the yolk sac, allantois and chorion. Three ventral segmental arteries remain as coeliac trunk, superior mesenteric artery and inferior mesenteric artery. Anatomical variations in the branching pattern of the celiac trunk are of considerable importance in liver transplants, laparoscopic surgery, invasive radiological interventions and penetrating injuries to the abdomen. Knowledge of variation found in the present case is very useful to kept in mind to avoid serious vascular complications.
