肝动脉三维灰阶超声造影用于诊断肝移植术后肝动脉并发症的价值

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 3D-CEUS images are intuitive , three-dimensional and clear , and have clinical application value in diagnosing of hepatic artery complications after liver transplantation.
