彩色多普勒超声对Budd-Chiari综合征合并血栓的诊断价值

Utility of color Doppler ultrasonography for diagnosing Budd-Chiari syndrome with thrombosis

目的探讨彩色多普勒超声对Budd-Chiari综合征(BCS)合并血栓的诊断及应用价值。方法对25例临床疑诊BCS合并血栓的患者进行彩色多普勒超声检查并与其他影像学检查对照。结果彩色多普勒超声对其中23例作出正确诊断,15例BCS合并新鲜血栓,8例BCS合并陈旧血栓,漏诊2例,2例均为BCS合并新鲜血栓,诊断符合率92%。结论彩色多普勒超声可以实时、动态、直观地显示下腔静脉、肝静脉及门静脉的各种病变以及血流动力学变化,既可判定肝静脉、门静脉及下腔静脉中有无血栓的存在,又能够区分新鲜与陈旧血栓,因而它可作为诊断BCS合并血栓的首选方法。

Objective To evaluate the utility of color Doppler uhrasonography （CDUS） for diagnosing Budd-Chiari syndrome （BCS） associated with thrombosis. Methods Twenty-five patients with clinically suspected BCS associated with thrombosis underwent CDUS examinations and correlations with other imaging techniques. Results Twenty-three patients were definitely diagnosed as BCS by CDUS ,who comprised 15 associated with fresh thrombosis and 8 associated with old thrombosis, while other 2 patients who associated with fresh thrombosis were misdiagnosed by CDUS. The diagnostic accuracy of CDUS for BCS in the group patients was 92%. Con- clusion CDUS can really,dynamically and directly reveal the varied pathologic and bemodynamic changes in the inferior vena cava （IVC）, hepatic veins （HV） and portal vein （PV）, it can not only accurately identify whether the presence of thrombus in IVC,HV and PV also can differentiate fresh thrombus from old thrombus,so that CDUS should be first selective modality to diagnose BCS associated with thrombosis.
