Rare variant of celiac trunk branching pattern associated with modifications of hepatic arterial vascularization.

The routine dissection of a male body revealed multiple anatomical variations of the celiac trunk and hepatic artery vascularization. The origin of the celiac trunk was on the left side of the abdominal aorta, next to the T12-L1 intervertebral disk. The celiac trunk gave off five branches: the left inferior phrenic artery, the left gastric artery, the accessory right hepatic artery, the common hepatic artery and the splenic artery (the last two arteries had a common origin in a hepatosplenic trunk). A right branch detached off the left gastric artery and anastomosed with the hepatic artery proper. The proper hepatic artery also anastomosed with the accessory right hepatic artery at the same level. Consequently, the entire hepatic arterial supply was from the celiac trunk - through two arteries directly and a third via the left gastric artery. The anatomical variant described in this case can be considered very rare. Thorough knowledge of such variants is important both for upper abdominal surgery and for imagistic and interventional radiology.
