布加综合征的多层螺旋CT诊断发表时间：2009-7-17 16:05:13 来源：中国创新医学网推荐　　马秀华,吕富荣,尤云峰,肖智博,黄铀新,李　越,张　瑜　　(重庆医科大学附属第一医院放射科,重庆400016)　　摘　要:目的　探讨多层螺旋CT(multislice spiralCT, MSCT)在布加综合征(Budd-Chiari syndrome, BCS)中的诊断价值。方法　回顾性分析28例经DSA或手术证实的布加综合征MSCT影像特点。结果　BCS的MSCT特点为:①CT平扫形态学改变:肝脏不规则增大15例,弥漫增大10例,未见明显改变3例;②强化特征:花斑状强化型11例,周边强化型6例,中央强化型8例,不规则强化3例;③CTA准确显示阻塞的部位及侧支循环血管:肝静脉闭塞3例;下腔静脉狭窄闭塞25例,其中7例伴肝静脉闭塞;显示肝外侧支循环16例,肝内侧支循环2例,肝内外均有侧支循环7例, 3例无侧支循环血管。结论　MSCT能准确直观反映布加综合征阻塞的性质、部位、范围、侧支血管及其与周围器官的空间关系,能从形态及功能上反映肝脏损害程度。　　关键词:布加综合征;体层摄影术,X线计算机;血管造影术　　中图法分类号:R442. 8;R575;R814. 42文献标识码:AMultislice CT diagnosis ofBudd-Chiari syndromeMA Xiu-hua,LU Fu-rong,YOUYun-feng,XIAO Zhi-bo,HUANGYou-xin,LIYue,ZHANGYu(DepartmentofRadiol-ogy,The FirstAffiliatedHospital,ChongqingMedicalUniversity,Chongqing 400016,China)　　Abstract:Objective　To evaluate themultislice CT(MSCT)in the diagnosis ofBudd-Chiari syndrome(BCS).Methods　CT features of 28 caseswith Budd-Chiari syndrome confirmed by DSA or operation wereretrospectively analyzed.Results　MSCT features ofBCS:①Themorphologic changes on CT plain scan:en-largementof caudate lobe of the liver(15 cases),diffuse enlargement of the liver(10 cases),no significantchanges(3 cases).②Enhanced features:mottled(11 cases),peripheral(6 cases),central(8 cases),ir-regular(3 cases).③CTA accurately showed the location and obstruction ofcollateralvascular circulation:he-patic vein(HV)occlusion(3 cases),inferiorvena cava(IVC)narrow occlusion(25 cases),andHV occlu-sion(7 cases). CTA also showed collateral circulation outside the liver(16 cases),inside the liver(2 ca-ses),both inside and outside the liver(7 cases),and no collateral circulation(3 cases).Conclusion　Mul-tislice CT can accurately and directly reflect the nature,position,scope,collateral circulation and space rela-tion,aswellas themorphologicaland functionaldamage of liver. MultisliceCT is a reliablemethod to diagnoseBCS and is useful in the treatmentofBCS.　　Key words:Budd-Chiari syndrome;tomography,X-ray computed;angiography
