摘要
目的:探讨布-加综合征(Budd-Chiari syndrome,BCS)肝脏64层CT动态强化规律及成像基础,分析CT血管成像技术(CTA)在Budd-Chiari综合征中的应用价值。材料与方法:对11例Budd-Chiari综合征病人进行三期增强检查,并对相关血管分别行最大密度投影(MIP)、容积成像(VR)和多平面重建(MPR),分析Budd-Chiari综合征患者肝脏64层CT动态强化的规律,并观察肝静脉、下腔静脉病变类型及肝内外侧枝循环情况。结果:11例螺旋CT动态增强的BCS患者3例为急性期,8例为慢性期。7例为肝静脉梗阻,4例为下腔静脉梗阻。门脉期肝脏周边强化型4例,中心强化型2例,斑片强化型1例,均匀强化4例。肝内侧支静脉开放6例,其它征象如肝肿大、肝脏尾叶增大、脾大、腹水、肝内外侧枝血管形成等表现也可见到。结论:64层螺旋CT动态增强扫描可无创性显示肝脏血流动力学变化,结合CTA技术,能直观、准确地显示血管梗阻平面及肝内、外侧支循环情况。
Purpose： To investigate the Budd Chiari syndrome （ Budd - Chiari syndrome, BCS） 64 layer CT dynamic enhancement pattern of liver and imaging, analysis of lit angiography （ CTA ） in Budd - Chiari syndrome. Materials and Methods： 11 cases of Budd - Chiari syndrome patients for three phase enhanced, and the related blood vessels respectively, for maximum intensity projection （MIP） , volume rendening （VR） and multi planar reconstruction （MPR） , analysis of Budd -Chiari syndrome in patients with liver 64 slice CT dynamic enhancement patterns, and to observe the hepatic vein, inferior vena cava and extrahepatic collateral circulation situaticn. Results： 11 cases of spiral CT dynamic enhanced BCS in 3 patients with acute stage, 8 cases of chronic phase. 7 cases of hepatic venous obstruction, 4 cases of inferior vena cava obstruction. The portal hepatic peripheral 4 enhanced cases, strengthen type in 2 cases, 1 cases of reinforcement patch. Homogeneous enhancement in 4 cases. Hepatic collateral vessels in 6 cases, other signs such as hepatomegaly, splenomegaly, increased the caudate lobe of liver, ascites, extrahepatic collateral vessels formation, performance can also be seen. Conclusion： 64 slice spiral CT dynamic enhanced scan can noninvasively display of hepatic hemodynamic changes, combined with CTA technology, can visually, accurately display vascular obstruction plane and intrahepatic, lateral branch circulation.
