Hepatectomy is the main option of treatment for liver cancer,and how to control the blood loss is an important issue for the recovery of patients.Continuous hepatic vascular occlusion(Pringle maneuver)is the oldest and simplest way for vascular occlusion and still used in clinical practice.But continuous hepatic vascular occlusion often gives rise to postischemic reperfusion injury due to clamping the portal vein and the hepatic artery in the hepatic pedicle.So intermittent clamping or hemihepatic vascular occlusion is recommended in complex liver resections or for patients with liver cirrhosis.Total hepatic vascular exclusion has the advantages of occlusion of vascular inflow and outflow of the liver,and is mainly used for patients with tumors invading the caval veins.Major hepatic veins and limited inferior vena cava reconstruction has been also achieved under inflow occlusion with extraparenchymal control of major hepatic veins.It is crucial to know how to select the optimal methods of hepatic vascular o
