布-加综合征的CT诊断

目的 探讨布-加综合征的CT影像特征及CT诊断价值。方法 对34例经静脉造影证实布-加综合征患者的CT表现进行回顾性分析。结果 肝脏体积增大伴尾叶增大29例（85．2％)，肝脏密度不均23例(67．6％)，肝内侧支血管18例(52．9％)，肝外侧支血管30例(88．2％)，下腔静脉钙化7例(20．5％)。结论 CT在显示肝脏形态、下腔静脉钙化及肝外侧支循环等方面有优势，在诊断布-加综合征上有较大的价值。

CT diagnosis of Budd Chiari syndrome

Objective To have a view of CT characteristics and discuss its role in diagnosis of Bndd-Chiari syndrome. Methods 34 cases were confirmed Budd-Chiair syndrome by trans-phlebography, and their CT data were given a review. Result 29( 85.2%)cases showed enlargement of entire liver and caudal lobe, 23(67.6%)showed uneven density,1(852. 9%) showed collateral vessels inside liver, 3(088.2%) showed collateral vessels outside liver, and 7(20.5%)showed calcification of inferior vena cava. Conclusion CT is superior in displaying physical characteristics, calcification of inferior vena cava and collateral vessels outside liver, playing an important role in Budd-Chiari syndrome.
