Hepatic hemangioma is a relatively common benign tumor of the liver, clinically the most common is cavernous hemangioma, the natural population autopsy detection rate is 0.35-7.3%, accounting for 5-20% of benign liver tumors. The patient was admitted to the hospital for 18 years due to the discovery of hepatic hemangioma. On examination: the abdomen was bulging, the lower edge of the liver was touched 10 cm below the umbilicus, the texture was tough with tenderness, there was no previous history of hepatitis B, all five items of hepatitis B were negative, the preoperative assessment of liver function was grade A. Intensive CT showed that the hemangioma was located in the right half of the liver and the left inner lobe of the liver, and it was a huge hemangioma. Six months ago, the patient showed symptoms of abdominal distension and abdominal pain after eating, and the patient had indications for surgery. After discussion in the department and active preoperative preparation, it was decided to perform an enlarged right hemicolectomy. Intraoperative exploration revealed that the hemangioma was located in the right hemihepatic and left inner lobe, with a size of about 40×35 cm, adhering to the abdominal wall and transverse colon. The patient’s left outer lobe accounted for about 35% or more of the liver volume and was estimated to be able to tolerate the operation, during which the inferior hepatic vena cava was dissected out freely, the upper blocking band was set aside, the first hepatic hilar was dissected out freely, the upper blocking band was set aside, the right hepatic artery was dissected out and ligated, the second hepatic hilar was dissected out freely, the free The right hepatic vein, middle hepatic vein and left hepatic vein were exposed, the third hepatic hilar was dissected freely, the short hepatic vessels leading from the inferior vena cava to the hemangioma were sutured and cut, and after blocking the first hepatic hilar, the right half of the liver and part of the left inner lobe were resected, during which the right hepatic vein, middle hepatic vein and right hepatic tip were closed and cut with a vascular closure device. The patient returned to the ward safely after the operation, and the cardiac monitoring showed stable vital signs. Postoperative pathology showed: hepatic cavernous hemangioma (right hepatic), the patient drank water on the first day after surgery, and was on a liquid diet on the second day after surgery.
