Abstract

目的 探讨婴幼儿动脉导管未闭(PDA)介入治疗对所合并的支气管狭窄或软化及肺炎的影响。 方法 选择2016年11月至2017年12月于安徽省儿童医院重症监护室和心内科住院,并接受PDA介入封堵治疗的4例患儿(年龄6.5~15.0个月)。除PDA外,患儿皆有重症肺炎,均并呼吸道形态异常。3例并左主支气管或其分支狭窄,其中1例并喉软骨发育不良;另1例并左主支气管重度软化。采用常规方法进行PDA封堵治疗。术后观察再发肺炎及治疗情况、肺部体征、胸片肺透亮度等。 结果 4例患儿PDA均成功封堵,且无残余分流等并发症。术后随访3~15个月,例1患儿术后5个月和6个月再患肺炎2次;例4患儿术后1个月再患肺炎1次,住院7~10 d治愈,均未再使用呼吸机。另2例至今未再患肺炎。随访中,肺部喘鸣音逐渐减轻或消失,胸片显示两肺透亮度趋于对称。 结论 婴幼儿PDA同时并支气管狭窄或软化以及重症肺炎时,PDA介入治疗有利于肺炎的治疗,可使肺炎反复发作的频次减少、程度减轻,起到改善或治疗支气管狭窄或软化的作用。
