【摘要】 目的：探讨三种封堵动脉导管技术的临床效果。方法：①Ｐｏｒｓｔｍａｎｎ 海绵塞子封堵法；②带纤毛弹簧圈置入法；③Ａｍｐｌａｔｚｅｒ（ 蘑菇伞） 封堵法。结果：应用Ｐｏｒｓｔｍａｎｎ 法封堵４５０ 例，弹簧圈置入法３０ 例，Ａｍｐｌａｔｚｅｒ 法３ 例均成功。结论：Ｐｏｓｔｍａｎｎ 法操作较为复杂，对血管损伤较大，器械均为国产化，但费用低廉。弹簧圈只适用于小型动脉导管的封堵。Ａｍｐｌａｔｚｅｒ 封堵法方法简单，不限年龄和动脉导管的大小，但价格昂贵，临床使用有一定的限制更多还原

【Abstract】 Objective: To review the clinical results of three different methods in elose of patent ductus arteriosus (PDA) Methods: ① Porstmann′s Ivalon plugging method; ② Sping eoil; ③ Amplatzer ductus occluder Results: We used Porstmann′s method in 450 cases, Sping coil 30 cases and Amplatzer occluder 3 cases All of them were successfully closed Conclusion: Porstmann′s method are relatively complicated, but all the equipment can be made domestically Sping coil method only limited in small ductus, Amplatzer occluder is simple, no limitation for age and size of ductus, but is expensive更多还原
