Percutaneous closure of ductus arteriosus (DA), preceded by a balloon exploration of the defect and a catheter scale examination of the foam plug, was performed on 47 patients aged from 6 to 54 years. The minimal internal diameter of DA varied from 3.7 to 11.6 mm. Successful occlusion was achieved in all the cases without major complications. Sustained improvement was observed in both clinical findings and laboratory parameters. No incidence of endocarditis, plug displacement or recanalization was noted during follow-up of 6 to 35 months. It revealed that ductal exploration with the balloon catheter is able to ascertain the actual occlusion diameter of the lesion and the catheter scale plug examination can ensure good matching between DA and the plug so that changing of plugs and ectopic embolisms can be avoided.
对47例年龄在6至54岁的患者进行了动脉导管（DA）的经皮闭合术，术前先对缺损进行球囊探查并对泡沫塞进行导管尺寸检查。DA的最小内径在3.7至11.6毫米之间。所有病例均成功闭塞，无重大并发症。临床症状和实验室指标均持续改善。在6至35个月的随访中，未发现心内膜炎、封堵器移位或再通的情况。结果显示，使用球囊导管进行导管探查能够确定病变的实际闭塞直径，而导管尺寸的封堵器检查可确保DA与封堵器良好匹配，从而避免封堵器更换和异位栓塞的发生。
