Replaced right hepatic artery coursing ventral to the portal vein: demonstration with 64-row CT and 3D reformatted images.

摘要

We report one case of replaced right hepatic artery coursing ventral to the portal vein. This variation, which was demonstrated by 64-row CT angiography and three-dimensional reformatted images, has never been reported. Surgeons involved in hepatic and biliopancreatic procedures should be aware of this possible variation, which has important surgical implications.
