目的探讨Budd-Chiari综合征(BCS)下腔静脉阻塞病变的多排螺旋CT(MSCT)表现及其诊断价值。方法对比分析14例BCS下腔静脉的MSCT和血管造影表现。结果下腔静脉造影证实下腔静脉膜性狭窄2例、膜性闭塞9例、节段性闭塞3例;下腔静脉内血栓形成6例;下腔静脉闭塞区钙化4例;下腔静脉远心端皆有不同程度的扩张增粗。MSCT显示的下腔静脉狭窄和闭锁病变、有无血栓形成以及下腔静脉的走行均与下腔静脉造影相符合;并能显示下腔静脉阻塞区近心端到右心房入口的距离。结论MSCT能全面显示BCS下腔静脉的病变情况,诊断价值高,能可靠的指导制订下腔静脉阻塞的治疗方案。
Objective To investigate the performance and diagnostic value of multislice spiral CT (MSCT) in Budd-Chiari syndrome (BCS) with inferior vena cava obstruction. Methods Comparing the MSCT and angiographic findings of 14 cases of BCS inferior vena cava. Results Inferior vena cava angiography confirmed inferior vena cava stenosis in 2 cases, membranous occlusion in 9 cases, segmental occlusion in 3 cases; inferior vena cava thrombosis in 6 cases; inferior vena cava occlusion in 4 cases; Heart ends are varying degrees of expansion thickening. MSCT revealed inferior vena cava stenosis and atresia, presence or absence of thrombosis, and inferior vena cava lineage coincided with inferior vena cava angiography; and shows the inferior vena cava occlusion zone proximal to the right atrium entrance distance. Conclusion MSCT can fully display the lesion of the inferior vena cava of BCS, which has high diagnostic value and can reliably guide the treatment of inferior vena cava obstruction.
