Rare variation of the celiac trunk and related review.

In this study, we report a rare variation of the branching of the celiac trunk. During a routine abdominal dissection on a female cadaver, we found the celiac trunk to emerge from the abdominal aorta as 2 roots named hepatogastric trunk and hepatosplenic trunk. The hepatogastric trunk arises from the anterior surface of the abdominal aorta and divides into an aberrant branch to the right lobe of the liver, a branch to the right hemi diaphragm, the left hepatic and the left gastric arteries. The hepatosplenic trunk, which arises 1.5 cm below the hepatogastric trunk, gave off the common hepatic and splenic arteries. The common hepatic artery divided into the gastroduodenal, the right branch to the hepatic and the cystic arteries. It is important to know the variations of hepatogastric trunk and hepatosplenic trunk for the success of surgical operations to the liver and radiological investigations of those regions.
