Abstract: Objective To discuss the application of transcatheter arterial embolization (TAE) in the diagnosis, treatment of grade Ⅲ, Ⅳ and partial grade Ⅴ traumatic liver rupture.Methods A total of 168 severe traumatic liver rupture were treated with TAE from July 2014 to December 2020, including 92 cases with grade Ⅲ injury, 67 cases with grade Ⅳ injury and 9 cases with grade Ⅴ injury. Its efficacy and related complications were observed.Results All 168 patients achieved hemostasis after TAE and no re-bleeding events occurred. One patient died. The main complications of liver trauma in the late stage of TAE were perihepatic infection and liver abscess, and pipuncture tube drainage could achieve good efficacy.Conclusion Under the condition that the damage of major blood vessels in the liver are excluded, for liver trauma above grade Ⅲ, even grade Ⅳ and partial grade Ⅴ injuries, as an emergency hemostatic measure, TAE has the advantages of both diagnosis and treatment, less trauma and less impact on the physiological function of the body, which is safe and effective.
