Transcatheter closure of patent ductus arteriosus (PDA) for preterm infants is increasingly performed after the Food and Drug Administration approval of the Amplatzer Piccolo Occluder device (Abbott Inc., Abbott Park, IL, USA) in the United States. We report three babies in whom transcatheter closure of PDA was unsuccessful; however, the PDA closed spontaneously in 1-5 days after the transcatheter attempt. The PDA remained closed during follow-up at 3 weeks, 10 weeks, and 17 months, respectively. Mechanical stimulation of the PDA by the wire during attempted device closure likely induced the PDA closure. Further studies are needed to evaluate whether this is a useful alternative therapy in this patient population.
在美国食品药品监督管理局批准美国雅培公司（位于伊利诺伊州雅培公园）的Amplatzer Piccolo封堵器后，越来越多地对早产儿进行经导管动脉导管未闭（PDA）封堵术。我们报告了3例经导管封堵PDA未成功的婴儿；然而，在经导管尝试封堵后的1 - 5天内，PDA自行闭合。在分别为期3周、10周和17个月的随访期间，PDA一直保持闭合状态。在尝试封堵装置时，导丝对PDA的机械刺激可能诱发了PDA闭合。需要进一步研究来评估这是否是该患者群体中一种有用的替代疗法。
