Abstract: Objective To explore the value of clinical application of the hemihepatic blood flow occlusion in hepatectomy. Methods After the dissociation occlusion of the hemihepatic artery, portal vein and hepaticvein, livers were partly removed. Results One out of 72 patients who underwent lobectomy of the liver recovered after 45 days in hospital, one after 32 days and  the others after 15-20 days. Conclusions The hemihepatic bloodstream occlusion may control the amount of bleeding in the operation of hemihepatic removal and keep the blood circulation of the remaining liver. It is a feasible and effective method which has little damage to the function of liver both during and after operation.
