Abstract    With the continuous development of minimally invasive surgical diagnosis and treatment technology, laparoscopic hepatectomy has gradually become the preferred treatment for liver-related tumors due to its advantages of less injury, less pain, and faster recovery. Protecting the blood supply and backflow of the liver during hepatectomy will affect the prognosis of patients. Therefore, as an important technical means of liver transplantation, vascular reconstruction technology has gradually been widely used in laparoscopic hepatectomy. Laparoscopic hepatectomy mainly involves reconstruction of the hepatic artery, hepatic vein, portal vein and inferior vena cava. The methods of vascular reconstruction mainly include: suture of vascular defects, end-to-end anastomosis of broken ends, repair of autologous peritoneal patch or polytetrafluoroethylene patch, replacement of autologous blood vessels, cryopreserved homologous blood vessels or artificial blood vessels. It is also particularly important to select the appropriate vascular reconstruction method according to the individual conditions of each patient.
