From March to May 1996 we performed transcatheter closure of patent ductus arteriosus with spring coils in 4 patients. Age ranged from 5 month to 11 years (mean 4.3 years). One of them had two previous Rashkind occluders with persistant shunt and other case had pulmonary valve stenosis, in this case we performed pulmonary valvuloplasty and after that closure of ductus arteriosus. Mean pulmonary arterial pressure was 10 to 38 mmHg (mean 18), QP/QS was 1.2 to 5.0 (mean 3.2). Immediate total occlusion occurred in two cases and the other had trivial shunt by doppler echocardiography. No complications were detected. In conclusion we believe that this device is another no surgical alternative to treat persistant ductus arteriosus. It is effective, it has a low cost, and all the patients are candidates. The procedure carries minimum risk and has no mortality.
1996年3月至5月，我们对4例患者采用弹簧圈经导管闭合动脉导管未闭。年龄从5个月至11岁（平均4.3岁）。其中1例曾使用过2个Rashkind封堵器但仍有持续分流，另1例合并肺动脉瓣狭窄，对此例我们先进行了肺动脉瓣成形术，然后再闭合动脉导管。平均肺动脉压为10至38mmHg（平均18mmHg），肺循环血流量与体循环血流量比值（QP/QS）为1.2至5.0（平均3.2）。2例即刻完全闭塞，另1例经多普勒超声心动图检查有微量分流。未发现并发症。总之，我们认为该装置是治疗动脉导管未闭的另一种非手术选择。它有效、成本低，所有患者均适合。该操作风险极小，无死亡病例。
