      目的  初步探讨实时三维超声造影(RT-3D-CEUS)用于评估肝移植术后肝动脉并发症的价值。
      方法   对2014年4月至7月在中山大学附属第三医院行肝移植的18例受者进行29例次彩色多普勒超声(彩超)、二维灰阶超声造影(2D-CEUS)和RT-3D-CEUS检查。RT-3D-CEUS的成功率并评价其图像质量及诊断肝动脉并发症情况。
      结果   29例次检查中, RT-3D-CEUS检查成功率93%(27/29)。RT-3D-CEUS的图像质量评分, 3分14例次, 2分13例次, 1分2例次。采用RT 3D-CEUS诊断肝动脉狭窄6例, 其中4例为RT-3D-CEUS发现, 后经CTA证实;2例在检查前已经由CTA或DSA诊断肝动脉吻合口狭窄。
      结论   RT-3D-CEUS检查能获得直观、清晰的肝动脉图像, 用于评估肝移植术后肝动脉并发症具有临床应用价值。

     

    Abstract:
      Objective   To study preliminarily on the value of real-time three-dimensional contrast-enhanced ultrasound (RT-3D-CEUS) for the diagnosis of hepatic artery complications after liver transplantation.
      Methods   From April to July in 2014, a total of 18 liver transplant recipients were examined 29 times, by color doppler ultrasound, contrast-enhanced ultrasound (2D-CEUS) and RT-3D-CEUS. The successful rate of RT-3D-CEUS was calculated. And the image quality and the diagnosis of hepatic artery complications were evaluated.
      Results   In the 29 times of RT-3D-CEUS examination, the successful rate was 93%(27/29). The image quality of RT-3D-CEUS got 3 points for 14 times, 2 points for 13 times and 1 point for 2 times. In 6 cases who were diagnosed hepatic artery stenosis by RT-3D-CEUS, 4 cases were first diagnosed by RT-3D-CEUS and confirmed by CTA, and 2 cases were diagnosed by CTA or DSA before RT-3D-CEUS.
      Conclusions   The RT-3D-CEUS examination can get intuitive and clear images, which has clinical application value in evaluating hepatic artery complications after liver transplantation.
