Abstract： 目的 评价经导管封堵外科结扎术后再通的动脉导管未闭(PDA)的效果.方法 1995年6月至2000年11月,14例外科结扎术后再通的PDA患者进行了经导管封堵术,男5例,女9例,年龄4～48岁,平均13岁.外科手术至介入治疗的时间为1个月至22年.经股静脉途径置入Amplatzer封堵器和Rashkind封堵伞;经股动脉途径置入可控弹簧圈.分别于术后24 h,1、3、6个月及1年以上行X线胸片和超声心动图随访.结果再通PDA为漏斗型12例,管型2例.动脉导管最窄处直径为1～8 mm,平均4 mm.封堵后10 min,主动脉弓降部造影示无残余分流11例,微量残余分流3例.技术成功率100%,无并发症.术后24 h超声心动图检查均无残余分流. 所有患者均于术后1～2 d出院.10例随访1～18个月,未发现封堵器移位及PDA残余分流.结论经导管封堵外科结扎术后再通的PDA是一种有效方法,可以替代外科二次手术.
