Budd-Chiari综合征伴下腔静脉阻塞的影像诊断

目的探讨不同的影像学方法对Budd-Chiari综合征（BCS）伴下腔静脉阻塞的影像诊断价值。方法回顾性分析自2000年1月至2006年6月我院收治的36例BCS伴下腔静脉狭窄或阻塞患者，行超声检查36例，CT扫描12例，均行下腔静脉造影后确诊。结果36例患者经超声、CT检查、DSA检查后诊断为BCS伴下腔静脉阻塞，其中膜型狭窄18例，膜型闭塞2例，节段型狭窄10例，节段型闭塞6例。结论超声是诊断BCS的首选方法，可显示下腔静脉阻塞的部位、类型、范围和阻塞程度；CT扫描能够较准确地反映下腔静脉阻塞时肝内血流动力学变化，结合CTA可准确显示阻塞部位、性质；下腔静脉造影检查为诊断BCS的金标准，能准确地显示病灶全貌，并可测定右心房、下腔静脉各段压力，为定位、定性诊断及指导介入治疗提供可靠依据。

Diagnosis for Budd-chiari Syndrome Accompanied by Thrombo Genesis of Inferior Vene Cava

Objective To explore clinical diagnostic value in Budd-chiari Syndrome Accompanied by Thrombo Genesis of Infexior Vene Cava.Methods 36 patients were diagnosed from January 2000 to June 2006, Doppler songraphy inspection was done in 36 cases, 12 eases of them were done by Crscanning, and all were checked by phlebography of IVC. Results 36 cases were diagnosised Buddchiari Syndrome Accompanied by Thrombo Genesis of Inferior Vcne Cava,in which 18 cases were film straitness,2 cases were film occlu sion, 10cases were segmental straitness, and 6cases were segmental occlusion. Conclusion Doppler songraphy was the first choice in diagnosis of the BCS. it can show type,limit and extent of the obstructed part; CT scanning can exactly reflect the haemodynamics change of the obstructed part in IVC,and quality of the the obstructed par combineing CTA;phlebngraphy d IVC was the gold standard in diagnosis of the BCS. It can show full view of focus of infection, and determine the pressure of right atrium and any part of IVC, offer reliable data for allocation or qualitation diagnosis and interventional therapy.
