We describe a surgical technique that allows identification and severing at the hilum of the hepatic artery and portal vein branches, which perfuse only segments V and VI of the right lobe of the liver. This is a technique that makes possible an anatomic resection of those segments. The bile duct and hepatic vein branches are ligated only when the liver parenchyma is sectioned. The technique was used in three patients with liver tumors. No patient received blood transfusions, and no postoperative local complications were observed.
