摘要
目的 研究未闭动脉导管的形态学分类及其对堵闭术的关系。方法 查阅 1986～ 1997年的动脉导管造影片共 12 0例 ,根据其显示未闭导管的大小及形态可分为 5个类型 ,分别用海绵塞子、弹簧圈及Amplatzer堵闭器予以堵闭。 结果 用海绵塞子及Amplatzer堵闭器堵闭均成功 ,未发生残余分流和再通病例 ;用弹簧圈堵闭 30例 ,3例术后发现残余分流 ,2例发生弹簧圈脱落。结论 应用弹簧圈堵闭术时选择A型病例最佳 ,B及C型易发生术后再通。
Objective To classify the morphology of patent ductus arteriosis according of their sites of narrowing into 5 groups.Methods Form 1986～1997, totally 120 cases of angiogram were studied. We used Ivalon plug, Gianturco coil and Amplatzer method for occlusion. Results Cases with Ivalon plug and Amplatzer device were all successful, no residual shunt or recanalization were found in the follow up. Among 30 cases using coil, 3 had residual shunt, 2 had dislodgement of coil.Conclusions In using coil to occluding PDA type A ductus was most successful, and in type B and C reopen may occur in follow up.
