摘要 目的探讨超声心动图在蘑菇伞封堵器治疗动脉导管未闭中的应用.方法8例动脉导管未闭(patent ductus arteriosus,PDA)患者,男5例,女3例,年龄6~51岁,平均年龄(16±6.9)岁,封堵术前应用超声心动图测定PDA最小内径,并与X线造影测值比较,无显著差异,术中全程指导监测封堵器位置是否正常、有无残余分流,术后3个月复查随访观察有无残余分流、脱落.结果8例患者均封堵成功,超声监测PDA共8例均为管型,超声心动图测得PDA内径为(6.50±2.29)mm,近主动脉弓处,X线造影PDA,最窄处内径为(6.88±2.0)mm,二者无显著差异(P>0.05),术后3个月CDFI示:大动脉水平无残余分流,患者术后左心腔,肺动脉内径均明显减小,肺动脉压基本恢复正常.结论超声心动图在对PDA的大小判断,在术中监测安置以及术后残余分流观察,血流动力学评价有较好的应用价值.
