The anatomical variations of the abdominal arteries are important due to its clinical significance. Various types of vascular anomalies are frequently found in human abdominal viscera, during cadaveric dissection and diagnostic radiological imaging. The present report describes a variation in the celiac trunk as found during routine dissection in a 59-year-old male cadaver. The celiac trunk (CT) was unusually lengthy and took origin from the left antero-lateral surface of the abdominal aorta. Altogether, there were five branches, including three classic branches of CT. The left phrenic artery (LPA) was the first branch of the CT. The remaining four branches were left gastric artery (LGA), splenic artery (SA), common hepatic artery (CHA) and gastroduodenal artery (GDA). There was an arterial loop between the posterior branches of the superior pancreatico-duodenal artery (SPDA), arising from the GDA, and the posterior branch of the inferior pancreatico-duodenal artery (IPDA), arising from the superior mesenteric artery (SMA). The arterial loop formed by the above arteries, supplied the head of the pancreas and duodeno-jejunal flexure. The embryological and clinical significance of above variations has been described.
