Abstract		Background/Aims: In a morphological study of the right hepatic veins anatomical characteristics of surgical importance were looked for. Methodology: 110 cadaveric human livers were prepared by the corrosion casts method. The corrfluence patterns of the superior right hepatic vein, the hepatocaval confluence, the accessory right hepatic veins and the anastomoses between hepatic veins in the right hemiliver were examined. Results Four types of the superior right hepatic vein, based on the length of its trunk and the conftuence pattern of its main tributaries were determined and their frequency was calculated. Type 1 was found in 20%, type II in 40%, type III in 25% and type IV in 15%. Accessory right hepatic veins with a minimai caliber of 0.4cm, which were always present in type IV, were also found in other types, all together in 27% of the casts. The tributary-free part of the superior right hepatic vein at hepatocaval confluence was longer than 1cm in 77%. In the right hemiliver 109 anastomoses were found in 29/110 liver casts. Conclusions: Knowing the characteristics of different superior right hepatic vein types and of the accessory fight hepatic veins may be useful in segmentoriented liver resections and in right side living resections.
