奇静脉迂曲扩张在布加氏综合征中的诊断价值

Azygos vein tortuous expansion in the diagnosis of Budd-Chiari syndrome

目的探讨奇静脉迂曲扩张在布加氏综合征中的诊断价值。方法对28例经血管造影证实的布加氏综合征患者的MRI资料进行回顾性分析,重点观察奇静脉的大小和形态变化。结果肝脏体积增大伴尾叶增大23例,明确显示下腔静脉狭窄或闭塞19例,肝外侧枝血管形成25例,腹水25例。28例患者奇静脉明显扩张迂曲,形成侧支循环。结论在低场强MRI对布加氏综合征患者的诊断中,奇静脉的变化有重要的价值。

Objective To explore the expansion of tortuous azygos vein in the diagnosis of patients with Budd-Chiari syndrome.Methods In 28 patients with Budd-Chiari syndrome confirmed by angiography,the MRI data were analyzed retrospectively,focusing on the observation of azygos vein.Results Liver volume increased in 23 cases,a clear stenosis or occlusion of the inferior vena cava in 19 cases,extrahepatic collateral angiogenesis in 25 cases,and ascites in 25 cases.28 patients had a remarkable expansion of tortuous azygos vein.Conclusion Low-field MRI is helpful in diagnosis of patients with Budd-Chiari syndrome.
