目的:分析布-加综合征的横轴位CT表现,并与肝硬化CT表现对照,提高该病的诊断准确率。方法:对经血管造影或CTA等多种影像诊断或证实的48例布加综合征的CT表现进行回顾性分析,同时选择48例乙肝后肝硬化的患者进行对照,分析两种病变在横轴位CT表现上的差异,并采用卡方检验进行统计处理。结果:布加综合征CT表现为尾状叶肿大28例,明显高于肝硬化患者的5例(p<0.05);左叶增大在肝硬化患者为40例,高于布加综合征患者的14例(p<0.05)肝脏周边部分及肝内门静脉分支区域在动脉期明显强化21例,门静脉期肝实质呈不均匀花斑状强化为46例,肝硬化患者未见上述表现(p<0.01);侧枝循环中心包膈静脉的开放在布加综合征23例,在肝硬化患者未显示(p<0.01)。结论:增强CT的横轴位表现对布-加综合征的诊断有很重要的提示作用。
OBJECTIVE: To analyze the transverse CT findings of Budd-Chiari syndrome and compare it with CT findings of cirrhosis to improve the diagnostic accuracy of the disease. Methods: CT findings of 48 cases of Budd-Chiari syndrome diagnosed or confirmed by angiography or CTA were retrospectively analyzed. 48 cases of patients with posthepatitic cirrhosis were selected for comparison. CT performance differences, and using chi-square test for statistical processing. Results: The CT findings of Budd-Chiari syndrome in 28 patients with caudate lobes were significantly higher than those in cirrhotic patients (p <0.05). Left lobe enlargement was found in 40 patients with cirrhosis and higher than that in Budd-Chiari syndrome In the 14 patients (p <0.05), the peripheral part of the liver and the portal area of the intrahepatic portal vein were significantly enhanced in 21 cases in the arterial phase, 46 cases were heterogeneous in the hepatic parenchyma in the portal vein and were not found in the patients with liver cirrhosis (p < 0.01). The collateral circulation of the phrenic veins was open in 23 Budd-Chiari syndrome patients, but not in patients with cirrhosis (p <0.01). CONCLUSION: The enhanced axial CT findings have important implications for the diagnosis of Budd-Chiari syndrome.
