Abstract: Hepatic artery reconstruction is one of the key procedures in liver transplantation. Accidental dissection of the hepatic artery to be reconstructed caused by donor and recipient factors or surgical factors will disrupt the surgical plan, increase the difficulty of arterial reconstruction, significantly prolong the operation time, increase the risk of postoperative arterial stenosis and thrombosis and probably lead to acute allograft failure, which requires emergency surgical interventions or even secondary liver transplantation. Understanding of how to avoid dissection of the artery to be anastomosed during liver transplantation and corresponding treatment will contribute to preventing the incidence of artery-related complications during liver transplantation and improving clinical prognosis of liver transplant recipients. In this article, the causes, prevention and treatment of hepatic artery dissection and hepatic artery reconstruction in donors and recipients during liver transplantation were illustrated.
