摘要(Abstract)：

目的评价新型Pul-Stent支架在姑息性右心室-肺动脉连接术(Sano分流术)后肺动脉狭窄中的临床应用价值。方法纳入2014年8月至2015年6月阜外医院9例肺动脉闭锁合并室间隔缺损行姑息性Sano分流术后肺动脉狭窄的患儿行新型Pul-Stent支架置入术。男5例,女4例;年龄4(1,9)岁;体重9～25(15.1±4.9)kg。结果 9例患儿共成功置入9枚支架,其中3例置入左肺动脉,6例置入右肺动脉。支架置入后,肺动脉狭窄处内径由术前(3.0±1.4)mm增加至(8.8±1.4)mm(P<0.001),跨狭窄处压力阶差由术前(73.2±21.4)mm Hg(1 mmHg=0.133 kPa)降至(36.1±18.8)mm Hg(P<0.001),右心室收缩压/主动脉收缩压比值由术前(0.7±0.2)降为(0.4±0.2)(P<0.001),差异均有统计学意义。术中1例球囊破裂,于外科术中置入肺动脉支架,无其他并发症发生。随访3(3,4)年,肺动脉支架无再狭窄、移位或断裂等,8例(8/9)接受了Ⅱ期根治术。结论新型Pul-Stent支架作为一种专门设计用于肺动脉狭窄的支架,应用于Sano分流术后肺动脉狭窄安全且有效。
