Background:
Many anatomical variations have been associated with the Celiac Trunk, of which most are classified as being asymptomatic.
Case Presentation:
In this article, we describe yet another anatomical variation involving the Celiac Trunk, Superior Mesenteric artery and the Inferior Pancreaticoduodenal Artery during routine cadaveric dissection. We identified a fourth branch of the Celiac trunk (quadrification) that communicated with the Superior Mesenteric artery at the point of origin of the Inferior Pancreaticoduodenal artery which we concluded to be the Anterior Inferior Pancreaticoduodenal artery.
Conclusion:
This anastomosis could be essential in the case of occlusion between the Celiac Trunk and the Superior Mesenteric artery.
