CASE REPORT Male, 49 years old, was admitted to the hospital with a one-week physical examination that revealed a space-occupying lesion in the liver. In this case, the hepatic hemangioma was extensive: the right liver was from top to bottom, and it was closely related to the inferior vena cava. (Figs. I-X) The tumor was covered medially by the inferior vena cava. There is also a smaller hemangioma in the left lateral lobe of the liver. I An oblique incision was made into the abdomen under the right costal margin, and after careful and simple exploration the first thing to do was not to free it, but first to find the right hepatic artery in the hepatoduodenal ligament and to ligate it! The right hepatic artery in this case is anomalous: it originates from the superior mesenteric artery and runs on the right side of the common bile duct, which makes it easier to find and manage. Secondly, then free the perihepatic ligaments: hepatic round ligament; hepatic falciform ligament; right and left coronary ligaments; and (a little on the left side) the right deltoid ligament: the adhesions below the liver and the posterior peritoneum. And gradually separate inward straight to the inferior vena cava. The short hepatic veins are treated and the liver is separated from the inferior vena cava so that the lesion and the right liver are completely under the control of the surgeon’s left hand. (The inferior vena cava is behind the operator’s left hand.) IV Blocking the hepatoduodenum, i.e., blocking the blood flow to the liver. The tumor is resected along the tumor margins, and the section is sutured to stop bleeding and then tied with a threaded hepatic needle. (Care should be taken to keep the right hepatic vein free of blood flow.) VI Small hemangioma in the left outer lobe should be treated with suture. Although the hepatic hemangioma was large and closely related to the inferior vena cava, we handled it correctly, so the operation went smoothly and there was not much bleeding. (less than 200 ml)
