Abstract: 目的评价用Amplatzer封堵器介入治疗继发孔型房间隔缺损(ASD)与动脉导管未闭(PDA)的疗效与安全性. 方法在x线透视和超声心动图或主动脉弓降部造影指导下,经导管置入Amplatzer封堵器施行ASD封堵术26例,PDA封堵术10例.术毕及术后24小时、1个月、3个月分别行超声心动图检查评估疗效. 结果 26例ASD患者共27个缺损,22例ASD球囊最大伸展直径12~32mm,4例ASD经食管超声心动图(TEE)测量直径>34mm,选择Amplatzer封堵器直径为13~38mm.24例25个缺损应用24只Amplatzer封堵器闭合成功,成功率92.3%.10例PDA封堵术均获成功.主动脉弓降部造影示动脉导管呈漏斗型8例、管型2例;未闭动脉导管最窄处直径为3.5~8.0mm.随访未发现封堵器移位及残余分流.1例PDA在术后4h出现心包积液,经心包穿刺置管引流后次日消失,病人痊愈出院.无其他严重并发症发生. 结论应用Amplatzer封堵器介入治疗ASD和PDA操作简便,安全,成功率高.
