Contrast-enhanced ultrasonography is easy to operate and does not require high inspection instruments. It is of great significance in the diagnosis of early hepatic artery thrombosis. This article reports a patient with early hepatic artery thrombosis after liver transplantation. Early liver Contrast-enhanced ultrasound suggested hepatic artery thrombosis. The diagnosis was further confirmed by hepatic arteriography, and then arterial thrombolysis was promptly treated. critical time and improve patient outcomes. The purpose of this paper is to investigate the value of contrast-enhanced ultrasound in the diagnosis of early arterial thrombosis after liver transplantation.
