Abstract   Objective To explore the risk factors contributing to the development of the ischemic-type biliary complication(ITBC) and the prevention of ITBC in a large subjects undergoing liver transplantations(LT) retrospectively. Methods    The ischemic-type biliary complication cases were classified with Clavien system. The risk factors of ITBC were evaluated by using a binary forward stepwise logistic regression analysis. Results    6.08%(11/181,ITBC group) recipients developed ITBC, all of the cases are BC above ClavienⅢb. Regression analysis of ITBC revealed that RI1d（P=0.0500,OR=0.916）, RI1w（P=0.0078,OR>999.999）had significant difference and contributed more to the development of ITBC. Conclusion    ITBC have bad prognosis. Hepatic arterial insufficiency(HAI) was an independent risk factor for ITBC. Modification of arterial construction technique can reduce incidence of ITBC, to keep hepatic artery fluent have the same values.
