Knowledge of the surgical anatomy of the hepatic veins is indispensable for extensive hepatectomy, transplantation of the liver and the treatment of hepatic trauma with avulsion of the hepatic veins. A total of 60 cadaveric livers, used were included in the present study. Common trunk formed by union of left and middle hepatic veins was found in 28/60 (46.66%) specimens. Common trunk formed by union of left hepatic vein and right and left radicals of middle hepatic veins was found in 7/60 (11.66%).In 25/60 (41.66%) specimens there was separate opening for left, middle and right hepatic veins. The average diameter of ostium and new ostium of the common trunk was 13.52±3.50 and 16.35±3.30 (mean±SD) respectively. The average length of the common trunk was fond to be 6.49±2.70 (mean±SD). The average diameter of right hepatic vein, middle hepatic vein and left hepatic vein was 10. 98±2.60, 8.82±2.54 and 8.20±1.87 (mean±SD). Preoperative delineation of this complex venous anatomy is very important. It provides vital information in the preoperative evaluation needed before performing a liver surgery.
