摘　　要：目的:分析彩色多普勒血流显像(CDFI)与超声造影的区别并探讨他们在检测肝移植术后肝动脉并发症中所发挥的作用。方法:对136例肝移植术后患者进行彩色多普勒血流显像检查,并观察肝动脉及肝实质的血流灌注是否出现异常。其中38例彩色多普勒血流成像为可疑异常者,遂采用CPS成像技术,即用Sono Vue及超声造影匹配成像技术行超声造影检查。结果:在全部136例病例中,98例患者的肝动脉多普勒血流的信号显示清晰,占总例数的72.06%,其中38例患者术后早期、多切面扫查,CDFI无法做到对肝动脉血栓形成(HAT)的排除;6例患者在超声造影后,肝动脉主干及分支走行正常,显示清晰;有1例患者术后1周自身肝动脉血流信号无清晰显示,在第11天后,临床医师对其行以超声造影诊断确诊为HAT;有1例患者肝内回声杂乱(10个月内)直接呈现出多发边界的回声区,最终临床确诊为HAT伴肝弥漫性梗死。结论:CDFI与超声造影可以互补,对肝移植术后肝动脉并发症诊断的准确性有提高的作用。Objective： To analyze the differences between color Doppler flow imaging （CDFI） and contrast enhanced ultrasound ,to explore their values in the detection of hepatic artery complications after liver transplantation. Method： 136 cases of liver transplantation patients were examined by color Doppler flow imaging, and to observe if the blood perfusion of hepatic artery and hepatic parenchyma was abnormal. Among them 38 cases with color Doppler flow imaging was suspected abnormalities, then using CPS imaging techniques, namely SonoVue and contrast-enhanced ultrasound imaging techniques to examine.Result： In all the 136 cases,The hepatic artery doppler blood flow signals of 98 patients showed clearly , accounting for 72.06% of the total number,CDFI can＆#39;t rule out of the HAT for the 38 cases with early postoperative and multiple section scan. After contrast-enhanced ultrasound,6 patients’ liver artery trunk and branch line were normal and showed clearly.1 patient’s hepatic arterial blood flow signals were not showed clearly 1 week after postoperative,11 days later, the patient was confirmed as HAT with contrast-enhanced ultrasound diagnosis. 1 patient’s CDFI showed intrahepatic echo clutter （in 10 months） and multiple echo of the border area, the final clinical diagnosis was HAT with diffuse infarction of the liver .Conclusion： CDFI and contrast-enhanced ultrasound can be complementary.They can improve the accuracy of diagnosis of hepatic artery complications after liver transplantation effect.
