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。
Objective To investigate the safety and efficacy of interventional closure in the treatment of PDA of low birth weight infants. Methods The clinical data of 11 children with persistent persistent pneumonia and heart failure with low weight were retrospectively analyzed. The curative effect and follow-up results were analyzed. Results All the 11 cases were successfully occluded, the pulmonary artery pressure decreased to normal after the occlusion, the cardiac function was improved, pneumonia was cured, no rupture of blood vessels, tamponade, malignant arrhythmia, aortic and pulmonary stenosis, hemolysis and residual shunt at occlusion , Occluder displacement and fall off and other serious complications. Conclusions For the conservative treatment of respiratory tract infection did not improve significantly, heart failure can not be effectively controlled, the formation of pulmonary hypertension in low birth weight PDA infants, may consider early interventional occlusion treatment.
