Abstract:
Objective ToinvestigatetheMSCTfeaturesanditsclinicalvalueofcoronaryarteryfistula(CAF)withsurgicalindication. Methods CTfindingsof36patientswithluminaltumorGlikedilationCAFprovedbysurgerywereanalyzedretrospectively.Bymeans ofMIP,CPR,MPRandVRreconstruction,wearrangedtheabnormalvesselsintogroupsaccordingtoitscharacteristics,andmeasured thediameterofdilatation.ThediagnosticaccuracyofMSCTforCAFwascomparedwithtransthoracicechocardiography.Results Among the36cases,drainagesitesof8caseswererightatrium,14casesrightventricle,2casespulmonaryartery,1caseleftatrium,9cases leftventricle,and2casescoronarysinus.Amongallcases,4casesoriginatedfromleftmainartery,2casesfromleftanteriordescending, 5casesfromcircumflexartery,and25casesfromrightCAF.Ofwhich,24casesunderwentfistulaligationwithextracorporealcirculation. 12casesweretreatedwithminimallyinvasivesurgery.ThediagnosticaccuracyofMSCTbeforesurgerywas100%(36/36),andthat ofechocardiographywasabout80.6%(29/36).Conclusion ReconstructiontechniqueofMSCTcanprovidetheinformationofthe CAFvesselsanditsorigin,courseandshapeoffistulaorificium.MSCTcanaccuratelylocateandguidethesurgicalapproach,especially forpreGinvasivesurgery,providingimportantinformationfortreatment.MSCTshouldbethebestimagingmethodforCAF.
