2023年2月第30卷第2期三维CTA和DSA图像融合技术对腹主动脉瘤腔内修复治疗术的效果评价刘辉来,文自祥(中山市人民医院介入医学科,广东中山528400)【摘要】目的探讨三维CT血管造影(3D-CTA)和数字减影血管造影(DSA)图像融合技术在腹主动脉瘤腔内修复治疗术(EVAR)中的应用效果。方法选取102例行EVAR手术的患者,均行3D-CTA及DSA检查,并将3D-CTA检查图像与DSA数据进行图像融合,比较不同检查方法对各个征象以及术后并发症的检出率。结果3D-CTA与DSA图像融合技术对FL直径缩小、TL直径占比增加、支架近端FL血栓化、支架远端FL血栓化的检出率均高于3D-CTA及DSA检查(P<0.05)。三种检查方法对夹层破裂、内漏、支架近端逆行撕裂、新发夹层的检出率比较,差异无统计学意义(P>0.05)。结论3D-CTA和DSA图像融合技术在EVAR术后效果评估中具有重要意义,能够及时发现并发症,为临床干预提供可靠依据。【关键词】腹主动脉瘤腔内修复术;三维CT血管造影;数字减影血管造影;图像融合技术中图分类号:R445.3文献标识码:Adoi:10.3969/j.issn.1674-4659.2023.02.0151EvaluationontheEffectofThree-DimensionalCTAandDSAImageFusionTechniqueonEndovascularAneurysmRepairLIUHuilai,WENZixiang(DepartmentofInterventionalMedicine,ZhongshanPeople'sHospital,Zhongshan528400,China)[Abstract]ObjectiveToexploretheapplicationeffectofthree-dimensionalCTangiography(3D-CTA)anddigitalsubtractionangiography(DSA)imagefusiontechniqueonendovascularaneurysmrepair(EVAR).Methods102patientswhounderwentEVARsurgerywereselected.Allpatientsunderwent3D-CTAandDSAexaminations,andthe3D-CTAexaminationimageswerefusedwithDSAdata.Thedetectionratesofvarioussignsandpostoperativecomplicationswerecomparedamongdifferentexaminationmethods.ResultsThedetectionratesofFLdiameterreduction,TLdiameterproportionincrease,proximalFLthrombosisanddistalFLthrombosisby3D-CTAandDSAimagefusiontechnologywerehigherthanthoseby3D-CTAandDSAexaminations(P<0.05).Nosignificantdifferencewasfoundinthedetectionratesofdissectionrupture,endoleak,proximalretrogradetearofstentandnewdissectionamongthethreemethods(P>0.05).Conclusions3D-CTAandDSAimagefusiontechnologyisofgreatsignificanceintheevaluationofpostoperativeeffectofEVAR,wh...
