- Abstract: Liver has exceptional regeneration capacity which makes live donor liver transplantation a good surgical option for patients waiting for donors. Hepatic veins play major role in transplantation surgeries. Variations of hepatic veins can have great impact on surgical approach and outcome of the surgery. In the present study, total number of hepatic veins, presence and absence of accessory veins and confluence with its varied patterns were studied. We found maximum cases with 2 and 3 major hepatic veins which indicate presence of confluence. Confluence between left and middle hepatic veins was highest with 38% of total 54% of cases with confluence. We also found confluence between middle and accessory hepatic vein which is not mentioned in any present classifications. In addition, we have measured confluence length and diameter which holds significance in hepatic resection and anastomosis. The mean confluence length was 0.88±0.39 cm while mean confluence diameter was 0.57±0.20 cm. We found accessory hepatic veins in 15% of cases. The knowledge of this surgical anatomy and associated variations is of paramount importance in liver transplantation, radiological interventional procedures of liver and hepatic tumor resection procedures.
