目的：探讨介入封堵治疗低体重婴儿 PDA 的安全性及有效性。方法回顾性分析11例肺炎迁延难愈并心力衰竭低体重 PDA 患儿的临床资料，分析手术疗效和随访结果。结果11例患儿均封堵成功，封堵后肺动脉压力降至正常，心功能改善，肺炎治愈，无血管破裂、心包填塞、恶性心律失常、主动脉及肺动脉狭窄、溶血、封堵处残余分流、封堵器移位及脱落等严重并发症。结论对于经内科保守治疗呼吸道感染无明显改善、心力衰竭无法有效控制、形成肺动脉高压的低体重 PDA 婴儿，可以考虑采取早期介入封堵治疗。

Objetive To explore the safety and efficacy of interventional treatment of low birth weight infants with patent ductus arteriosus(PDA). Methods A retrospective analysis of the clinical data of 1 1 ca-ses of low birth weight children with PDA with pneumonia protraction and heart failure,which focused on the need for surgery,the clinical efficacy and follow-up results. Results 1 1 cases of patients were successfully occluded.After occlusion the pulmonary artery pressure decreased to normal.It was also improved the heart function and outcomes of pneumonia.Without blood vessels rupture,cardiac tamponade,malignant arrhythmia, aortic and pulmonary stenosis,hemolysis,residual shunt,occluder displacement and other serious complica-tions. Conclusions Early interventional therapy in low birth weight infants with PDA is safe and effective, when there are no significant improvement of conservative treatment for respiratory tract infections,heart failure and pulmonary hypertension.
