摘要
目的探讨超声造影三维成像技术在移植肝肝动脉检查中的应用价值。方法对25例移植肝患者肝动脉进行二维及三维超声造影检查。评价三维图像中肝动脉显示的分支分级、图像质量水平;评价三维超声造影对移植肝动脉并发症的诊断价值。结果三维超声造影诊断移植肝血管通畅者20例,三维超声造影可显示肝动脉的树状结构,三维超声造影显示的肝动脉分级及图像质量均优于二维造影(P=0.0000)。三维超声造影正确鉴别诊断了3例移植肝动脉扭曲及2例肝动脉狭窄。结论三维超声造影可更清晰显示移植肝动脉结构,可提供比二维超声造影更丰富的诊断信息。
Objective To evaluate the value of three-dimensional contrast-enhanced ultrasonography（3D-CEUS） in the examination of hepatic artery（HA） of transplanted liver.Methods Thirty-two patients suspected of hepatic artery complications after liver transplantation were examined by two-dimensional contrast-enhanced ultrasonography（2D-CEUS） and 3D-CEUS.The visualization of branching orders and imaging quality were assessed between 2D-CEUS and 3D-CEUS.The diagnostic value of hepatic artery complications after liver transplantation with 3D-CEUS was also evaluated.Results 3D-CEUS showed twenty patients with patent hepatic vessels,and follow-up results confirmed 3D-CEUS findings.The three dimensional hepatic artery tree structures were visualized in all the patent arteries by 3D-CEUS.The HA branch-level and the image quality of HA shown on 3D-CEUS was superior to that on 2D-CEUS（P=0.000）.Five patients with hepatic artery complications were diagnosed with 3D-CEUS,including tortuous hepatic artery in 3 patients and hepatic artery stenosis in 2 patients,following CTA or DSA demonstrated the results.Conclusions 3D-CEUS is a useful technique to visualize the hepatic artery and can provide more diagnostic information than 2D-CEUS.
