Abstract
Aims: To report a rare variation of the blood vessels supplying the liver in Japanese.
Method: With the gross dissection method, the main abdominal organs were removed in one bloc to observe the blood vessels supplying liver.
Results: The vessels of the liver have four branches: the left hepatic artery, the right hepatic artery, a branch to the quadrate lobe, and a branch to the caudate lobe of the liver.
Conclusion: This rare variation of the blood vessels supplying the liver is useful for clinical examination and surgical treatment.

Keywords: Blood supply variation, Celiac trunk, Hepatic artery, Human, Superior mesenteric artery
