Tei指数评价患儿房间隔缺损修补术前后右室功能000.doc

Tei指数评价患儿房间隔缺损修补术前后右室功能摘 要 目的 应用Tei指数技术早期评价患儿房间隔缺损修补术前后右室功能。方法 手术治疗单纯ASD组患儿30例,体检健康儿童30例为对照组。超声测量右房横径(RA)和右室横径(RV),Simpson法测得右室容积,计算右室射血分数(RVEF);并测量三尖瓣射血间隔时间,计算Tei指数。结果①ASD组手术后1个月复查房间隔水平无残余分流。②ASD组术前RA和RV较对照组增高,术后1、3个月RA和RV较术前降低,差异均有统计学意义(P﹤)。③ASD组术前、术后1、3个月右室Tei指数均较对照组增高,术后1,3个月右室Tei指数较术前增高,差异均有统计学意义(P﹤)。结论 Tei指数可用于评价患儿ASD修补术前后右室功能的变化。关键词 Tei指数;右室功能;房间隔缺损Evaluationofrightventricularfunctioninpediatricpatientswithatrialseptaldefectpre-andpostoperativelywithTeiindexYanXinJi(DepartmentofUltrasound,CentralHospitalofWuLanChaBuCity,Jining012000,China)[Abstract]Objective:To exploretheapplicationofTeiindexin earlyassessing rightventricularfunction ofpediatricpatientswithatrialseptaldefect(ASD)pre-:30casesofoperationfortreatmentofASDpatients,(RA)andrightventriculartransversediameter(RV),rightventriculartovolumetestingusingtheSimpsonmethod,thecalculationofrightventricularejectionfraction(RVEF);andmeasuringthreetricuspidejectioninterval,:①.;②groupASD,preoperativeRAandRVhigherthancontrolgroup,after1,3monthsofRAandRVdecreased,thedifferencewasstatisticallysignificant(P<).;③IngroupASD,preoperativeandpostoperative1,3monthsofrightventricularTeiindexwerehigherthancontrolgroup,after1,3mo
