实时三维超声造影评估肝移植术后肝动脉并发症的初步探讨

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。

Preliminary study of real-time three-dimensional contrast-enhanced ultrasound for evaluating hepatic artery complications after liver transplantation

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 201 4,a total of 1 8 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 1 4 times,2 points for 1 3 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.
