Anatomy of the hepatic veins and common anatomical variants. a Normal anatomy (common variant); right hepatic vein (RHV) and common trunk of the middle (MHV) and left hepatic vein (LHV). IVC = inferior vena cava. b Accessory right hepatic vein (mostly segment 8 vein) (aRHV) draining in a common trunk with the MHV and LHV. c Accessory inferior right hepatic vein (IHV) seen in 47% of cases [8]. d CT scan of a patient with a tumor located in liver segments 7/8 and the anatomic variation of an inferior hepatic vein. In this case, resection of segment 7 and 8 with resection of the right hepatic vein without reconstruction was possible. Outflow of the liver segments 5 and 6 via the strong inferior hepatic vein was sufficient. The yellow line encircles the resection area of the tumor with the right hepatic vein
