摘　　要：目的：评价ＣＴ、超声、静脉造影对Ｂｕｄｄ－Ｃｈｉａｒｉ综合征的诊断价值。方法：回顾性分析４４例Ｂｕｄｄ－Ｃｈｉａｒｉ综合征的ＣＴ、超声、静脉造影表现，比较三种检查方法显示肝脏的形态、肝静脉、下腔静脉、肝内外的侧枝血管情况。结果：ＣＴ显示肝尾叶增大４２例（９５％），肝脏密度不均或呈低密度表现，１９例（４３％）显示有肝内侧枝血管，４２例（９５％）见有肝外侧枝血管，其中奇静脉扩张３５例（８０％），半奇静脉扩张３９例（８９％），下腔静脉钙化７例（１６％）。超声显示３８例（８６％）有下腔静脉狭窄或阻塞，１６例（３６％）有肝静脉狭窄或阻塞，３７例（８４％）显示有肝内侧枝血管，１６例（３６％）显示有肝外侧枝血管。静脉造影显示下腔静脉狭窄或阻塞２３例（５３％），肝静脉狭窄或阻塞５例（１１％），其余１６例（３６％）同时累及下腔静脉和肝静脉，３８例（８４％）显示有肝内侧枝血管，４４例（１００％）见有肝外侧枝血管。结论：ＣＴ对显示肝脏形态、下腔静脉钙化、肝外侧枝血管尤其是奇静脉和半奇静脉扩张有优势，超声则对显示下腔静脉和肝静脉狭窄或阻塞、肝内侧枝血管有优势，ＣＴ。Objective:To evaluate CT,sonography and venography in diagnosis of Budd-Chiari syndrome.Methods:The CT,sonographic and venographic data of 44 cases with Budd-Chiari syndrome were retrospectively studied.The findings of hepatic morphology,hepatic veins,inferior vena cava and collateral vessel on these three imaging modalities were compared.Results:CT showed caudate lobe enlage in 42(95%),intrahepatic collateral vessels in 19(43%),extrahepatic collateral vessels in 42(95%),the dilatation of azygous vein in 35(80%),the dilatation of semiazygous vein in 39(89%),calcification in the inferior vena cava in 7(16%).Sonography demonstrated narrowing or obstruction of the inferior vena cava in 38(86%),of the hepatic veins in 16(36%),intrahepatic collateral vessels in 37(84%)and extrahepatic collateral vessels in 16(36%).Venography identified narrowing or obstruction of the inferior vena cava in 23(53%),of the hepatic veins in 5(11%),of both the inferior vena cava and the hepatic veins in 16(36%),intrahepatic collateral vessels in 38(84%),extrahepatic collateral vessels in 44(100%).Conclusion:CT has superiority in delineating hepatic morphology,calcification of the inferior vena cava,extrahepatic collateral vessels,especially in showing dilatation of the azygous vein and semiazygous vein.Sonography has superiority in demonstrating narrowing or obstruction of the inferior vena cava and hepatic veins,intrahepatic collateral vessels.CT,sonography and venography are complementary in diagnosis of Budd-Chiari syndrome.
