彩色多普勒超声在诊断布-加综合征中的应用价值

目的探讨不同类型布-加综合征(BCS)患者的彩色多普勒声图像特征及其诊断价值。方法回顾性分析48例经血管造影或手术证实的BCS患者,对其二维及彩色多普勒声像图特征进行分析和比较,并计算超声诊断的准确率。结果 48例BCS中,超声诊断准确率91.7%(44/48),其中肝静脉型8例,下腔静脉型21例,混合型15例。副肝静脉、右后下肝静脉和腰升静脉是常见的侧支循环通路。肝尾状叶增大是BCS最多见的间接征象(42/48)。结论彩色多普勒超声可以准确诊断不同类型BCS,在侧支血管检出方面优势明显,可作为诊断此病的首选影像学检查方法。

The value of Color Doppler Ultrasonography in diagnosis of Budd-Chiair Syndrome

Objective To study the color Doppler imaging characteristics in different types of Budd-Chiair Syndrome （BCS） and to assess its value in diagnosis of BCS. Methods The characteristics of two-dimension and color Doppler imaging were analyzed retrospectively in 48 patients with BCS, who were all confirmed by angiography or surgery. The accuracy was calculated. Results In 48 patients with BCS, the obstruction of liver vein was found in 8 cases, the obstruction of inferior venae cava in 21 cases and both in 15 cases. The accuracy of color Doppler imaging was 91.7% （44/48）. The accessory hepatic vein, inferior right hepatic vein and ascending lumbar vein were common collateral circulations. And caudate lobe hypertrophy was the most common indirect sign （42/48）. Conclusion Color Doppler imaging can diagnose different types of BCS exactly, especially in detection of collateral circulations, which should be the initial diagnosis procedure for Budd-Chiari syndrome.
