128层CT肺血管成像对急性肺栓塞严峻程度的评估翻开文本图片集【】目的：探讨128层CT肺血管成像〔CTPA〕在急性肺动脉栓塞严峻程度评估中的价值。方法：选择行CTPA检查确诊的肺栓塞患者44例作为争辩对象，依据CT肺动脉堵塞指数Mastora评分方法将患者分为轻、中、重度三组，在CT横断面上分别测量右心室〔RV〕、左心室〔LV〕最大短轴直径，主肺动脉〔MPA〕、升主动脉〔AA〕、上腔静脉〔SVC〕、奇静脉〔AV〕直径，并计算右心室最大短轴直径〔RVd〕与左心室最大短轴直径〔LVd〕之比及主肺动脉直径〔MPAd〕与升主动脉直径〔AAd〕比值；观看AV、下腔静脉〔IVC〕、肝静脉〔HV〕、冠状静脉〔CV〕等比照剂返流状况。结果：随着肺动脉堵塞指数增加，CT横断面RVd增大，LVd减小、RVd/LVd比值增加；SVC和AV扩张，AV、IVC、HV、CV比照剂反流更加明显；MPAd/AAd比值增加。结论：128层CTPA可帮助推断急性肺栓塞的严峻程度，为临床选择治疗方法、判定预后及观看疗效供给必要的挂念。【关键词】肺栓塞；肺动脉；体层摄影术；X线计算机；严峻性AssessmentoftheSeverityofAcutePulmonaryEmbolismby128SliceCTPulmonaryAngiography/HanLi-liang，LIUJin-ping，JINJu-sheng.//MedicalInnovationofChina，2023，13〔04〕：134-137【Abstract】Objective：Toevaluatethevalueof128sliceCTpulmonaryangiography〔CTPA〕intheassessmentofacutepulmonaryembolism〔APE〕.Method：44pulmonaryembolismpatientswithCTPAexaminationwereselectedastheresearchobjects.AccordingtotheMastorascoringmethodofCTpulmonaryarterialobstructionindextheyweredividedintothemild，themoderateandtheseveregroup.OntransverseCTimages，Themaximumshortaxisdiametersofrightventricular〔RV〕andleftventricular〔LV〕，thediametersofmainpulmonaryartery〔MPA〕，ascendingaorta〔AA〕，superiorvenacava〔SVC〕andazygosvein〔AV〕weremeasured.Theratiooftherightventricularmaximumshortaxisdiameter〔RVd〕andleftventricularshortaxisdiameter〔LVd〕，theratioofmainpulmonaryarterydiameter〔MPAd〕andascendingaorticdiameter〔AAd〕werecalculated.Thesituationofcontrastagentsregurgitationofazygosvein〔AV〕，inferiorvenacava〔IVC〕，hepaticvein〔HV〕andcoronaryvein〔CV〕wereobserved.Result：Withtheincreaseofpulmonaryarterialobstructionindex，theRVdofCTwasinc...
