摘要
摘要目的分析慢性脑供血不足(CCCI)患者经颅多普勒超声(TCD)检查的特点,探讨TCD在CCCI诊断中的应用价值.方法对１５０例CCCI患者和３００名对照者行TCD检查,并进行两者的比较.结果两组TCD单支血管狭窄率、PI、RI值比较均无统计学差异,试验组血流速度异常率较对照组明显增高(８６??６７％vs６８??６７％,P＜０??０５);CCCI组低流速比例高于对照组(５４??３１％vs３２??３３％,P＜０??０５),CCCI组多支血管血流速度减慢更常见(P＜０??０５).结论CCCI患者TCD常见多支血管血流速度减慢,有重要诊断价值.关键词慢性脑供血不足;经颅多普勒超声;血流速度TCDAnalysisof１５０PatientswithChronicCerebralCirculationInsufficiencyWeiHong－shi,FengYan－rong??NanJingTongRenHospital,２１１１０２AbstractObjectiveToanalyzethefeatureoftranscranialdopplerultrasonography(TCD)inpatientswithchroniccerebralcirculationinsufficiency,CCCI)anddeterminethediagnosisvalueofTCDforCCCI??MethodsToperformTCDtestsandcomparewiththeResultsbetween１５０casesofCCCIand３００controls??ResultsTherewerenostatisticalsignificantdifferencesbetweensinglevascularstenosisrate,PI,RI,butwerestatisticallysignificantdifferencesinbloodflowveＧlocitybetweentwogroups(８６??４６％vs６８??６７％,P＜０??０５);inCCCIgroup,thelowvelocityratewashigherthanthoseinthecontrolgroup(５４??３１％vs３２??３３％,P＜０??０５);multiplevascularlowbloodflowvelocityinCCCIwasmuchmorethanthoseinthecontrolgroup(P＜０??０５)??ConclusionThereweremultiplelowbloodflowvKeleoycitwyoridnsCCCI,TCDmakeanimportantroleindiagnosisinpatientswithCCCI??Chroniccerebralcirculationinsufficiency;TCD;Bloodflowvelocity中图分类号R７４３．３文献标识码A文章编号１００８－６３１５(２０１５)１２－０１７７－０１
