Doppler is the screening modality of choice for assessment of patients suspected of Budd Chiari syndrome (BCS). The aim of this study was to compare the diagnostic value of contrast enhanced ultrasound (CEUS) with Doppler in the initial evaluation of patients with BCS.
This was a retrospective study of patients with suspicion of BCS who underwent CEUS of the hepatic veins and inferior vena cava between July 2017 and April 2019. CEUS was performed using Sonovue. All patients underwent Doppler evaluation of the hepatic veins and inferior vena cava. The final diagnosis of BCS was based on transvenous or percutaneous digital subtraction venography. The diagnostic accuracy of CEUS was compared with Doppler.
A total of 19 patients (median age, 30 years; 11 males) were evaluated with CEUS and Doppler. A final diagnosis of BCS was established on digital subtraction venography in 15 patients. CEUS was found to have a 100% sensitivity and 75% specificity. The sensitivity and specificity of Doppler was 100% and 25%. The diagnostic accuracies of CEUS and Doppler were 94.74% and 84.29%, respectively.
CEUS is a useful adjunct to the Doppler in the initial assessment of patients with BCS. However, further prospective studies must confirm our preliminary observations.
多普勒是疑诊布加综合征（BCS）患者的首选筛查方式。本研究旨在比较超声造影（CEUS）与多普勒在 BCS 患者初始评估中的诊断价值。
这是一项回顾性研究，纳入了 2017 年 7 月至 2019 年 4 月间疑似 BCS 而行肝静脉和下腔静脉 CEUS 检查的患者。CEUS 使用 SonoVue 进行。所有患者均行肝静脉和下腔静脉多普勒评估。BCS 的最终诊断基于经静脉或经皮数字减影血管造影。比较了 CEUS 与多普勒的诊断准确性。
共 19 例（中位年龄 30 岁；男性 11 例）患者同时接受了 CEUS 和多普勒检查。15 例患者经数字减影血管造影确诊为 BCS。CEUS 的灵敏度和特异度分别为 100%和 75%。多普勒的灵敏度和特异度均为 100%和 25%。CEUS 和多普勒的诊断准确性分别为 94.74%和 84.29%。
CEUS 是 BCS 患者初始评估中多普勒的有用辅助手段。然而，还需要进一步的前瞻性研究来证实我们的初步观察结果。
