B-TFE与3D DCE-MRA联合应用在布加综合征诊断中的价值

目的探讨B-TFE与3D DCE-MRA联合应用在布加综合征（BCS）诊断中的价值。材料与方法搜集经DSA证实的布加综合征患者32例,其中8例为单纯下腔静脉阻塞,2例为单纯肝静脉阻塞,22例为下腔静脉阻塞伴肝静脉阻塞。32例患者均行B-TFE和3D DCE-MRA检查,分析两种方法及联合应用时对BCS及其侧支循环的显示情况。结果 B-TFE正确诊断8例下腔静脉阻塞、18例下腔静脉阻塞伴肝静脉阻塞和2例肝静脉阻塞,总检出率为87.5%（28/32）;3D DCE-MRA正确诊断8例下腔静脉阻塞、19例下腔静脉阻塞伴肝静脉阻塞和1例肝静脉阻塞,总检出率为93.8%（30/32）。B-TFE共显示个193侧支循环,3DDCE-MRA则显示248个侧支循环。两者结合准确诊断全部BCS及其肝内外侧支循环。结论联合应用B-TFE和3DDCE-MRA是诊断BCS的理想方法。I

Diagonostic value of combined with Budd-Chiari syndrome

Objective:To evaluate the value of B-TFE combined with 3D DCEMRA in diagnosis of Budd-Chiari syndrome(BCS).Materials and Methods:32 cases with BCS proved by DSA were performed with B-TFE and 3D DCE-MRA imaging,among which 8 cases were inferior vena cava(IVC) obstruction,22 cases were IVC and hepatic vein(HV) obstruction,and 2 cases were HV obstruction.The obstruction of IVC and HV and collateral circulation were recorded on both methods images.Results:B-TFE accurately displayed 8 case with ICV obstruction,18 cases with IVC and HV obstruction,and 2 cases with HV obstruction;the correct rate was 87.5%(28/32).3D DCE-MRA accurately displayed 8 case with ICV obstruction,19 cases with IVC and HV obstruction,and 1 case with HV obstruction,the correct rate was 93.8%(30/32).B-TFE showed 193 collateral vessels,and 3D DCE-MRA showed 248 collateral vessels.Combined B-TFE with 3D DCE-MRA,all of BCS and collateral circulation were accurately displayed.Conclusion Combine B-TFE with 3D DCE-MRA is an ideal diagnostic method for BCS.
