Abstract:

Few reports describe the combined variations of hepatic artery and vein involved in liver cancer. We report a 63-year-old woman with liver cancer planed for right hemihepatectomy. The multi detector computer tomography angiography and three-dimensional construction of liver vasculature were performed. The patient was diagnosed as a Michel’s type III hepatic artery variation. A replaced right hepatic artery arose from the superior mesenteric artery and had distributed into the right liver lobe. Additionally, a large inferior right hepatic vein drained segment VI and emptied into the inferior vena cava was present at the lower border of the liver. Not only the assessment of hepatic arterial variation is mandatory in patient undergoing hepatectomy, but also the variation of hepatic vein should be thoroughly assessed for hepatic surgery.
