To introduce modified operation of patent arterial ductcomplicated with severe pulmonary hypertension and to study it sfeasibility,safety and indications.Methods Occlusion of the openings of main artery and side artery was performed through double-channeled air pocket tube,with normothermia,normal flowing rate and heart beating. Results 16 patients were all cured and no operative complications occurred with follow-up of 2 months to 3 years showing satisfactory condition.Conclusion The modified operation is indicated to patients with patent duct artery (PDA) complicated with moderate and severe pulmonary hypertension accomp a nied by tumorlike expanding or calcification or infective endocarditis.And cardic pulmonary complications and the impact resulted from deep hypothermia are decreased.%目的介绍巨大动脉导管未闭合并重度肺动脉高压的一种改良术式及其可行性、安全性和适应症。方法采用经肺动脉双腔气囊导管封堵主动脉侧动脉导管开口,常温、常规流量,心脏不停跳缝闭动脉导管开口。结果16例均治愈,无手术并发症发生,随访2月~3年情况良好。结论改良术式适用于动脉导管未闭合并中、重度肺动脉高压且伴有瘤样扩张、钙化及合并心内膜炎患者,明显减少了心肺并发症及深低温对全身的不良影响。
