摘　　要：目的探讨肝动脉三维灰阶超声造影(3D-CEUS)用于诊断肝移植术后肝动脉并发症的价值。方法对26例肝移植供体或怀疑肝动脉并发症的肝移植受体进行常规彩超、二维灰阶超声造影(2D-CEUS)和3D-CEUS检查。评价3D-CEUS的图像重建成功率及重建的肝动脉三维图像质量。结果 26例患者3D-CEUS可显示21条肝动脉,图像重建成功率81%。用3D-CEUS重建的肝动脉三维图血管连续性好,可显示冠状面Z轴上的、细小或迂曲的分支或属支,能帮助判定肝动脉段分支起源,能明确地显示血管的空间关系。结论 3D-CEUS检查具有三维图像直观、立体、清晰的特点,在诊断肝移植术后肝动脉并发症中具有临床应用价值。Objective To investigate the value of three-dimensional contrast-enhanced ultrasound （3D-CEUS） in diagnosing the hepatic artery complications after liver transplantation. Methods A total of 26 liver transplant donors or recipients suspected with hepatic artery complications were examined by color Doppler ultrasound, two-dimensional contrast-enhanced ultrasound （2D-CEUS） and 3D-CEUS. The successful reconstruction rates of 3D-CEUS and the three-dimensional image quality of reconstructed hepatic arteries were evaluated. Results In the 26 patients, 21 hepatic arteries could be visualized with a successful reconstruction rate 81%. The three-dimensional images of hepatic arteries by 3D-CEUS were continuous. The coronal （Z- axle） , fine or circuitous branches or tributaries could be visualized well. The segmental hepatic arteries origin could be determined and the spatial relationship of vessels could be visualized definitely. Conclusions The 3 D-CEUS images are intuitive, three-dimensional and clear, and have clinical application value in diagnosing of hepatic artery complications after liver transplantation.
