摘　　要：目的探讨CEUS对肝移植术后肝动脉并发症的诊断价值。方法对135例肝移植患者术后定期行常规超声检查,对其中疑有肝动脉病变的39例进一步行CEUS检查。结果 39例中,CEUS诊断4例肝动脉血栓(HAT),其中2例合并大范围肝坏死,1例伴侧支循环形成;8例为肝动脉狭窄(HAS);1例为肝动脉假性动脉瘤(HAP)。HAT、HAS及HAP发病率分别为2.96%(4/135)、5.93%(8/135)及0.74%(1/135)。结论 CEUS可提高超声对肝移植术后肝动脉并发症诊断的准确性。Objective To assess the diagnostic value of contrast-enhanced ultrasound（CEUS） in hepatic artery complications after liver transplantation.Methods Conventional ultrasound was performed regularly on 135 patients after liver transplantation,and 39 patients with suspected hepatic artery complications underwent CEUS with SonoVue.Results In the 39 patients,hepatic artery thrombosis（HAT） was found in 4 cases,2 of them with large area necrosis in liver and 1 with collateral blood flow.Hepatic artery stenosis（HAS） and hepatic artery pseudoaneurysm（HAP） were detected in 8 and 1 patient,respectively.The incidence of HAT,HAS and HAP was 2.96%（4/135）,5.93%（8/135） and 0.74%（1/135）,respectively.Conclusion CEUS can improve the diagnostic accuracy of hepatic artery complications after liver transplantation.
