为总结应用成角型蘑菇伞封堵小儿动脉导管未闭(简称PDA)的经验,回顾性分析15例5.5个月 -8岁(平均2.8±2.5岁)小儿应用此技术的资料。PDA最小直径为2-10 mm(平均为5.9±3.1 mm),术前均有肺动脉高压,平均肺动脉压为34-65 mmHg。选用新型封堵伞直径6-20mm(平均12.9±4.2 mm)。结果表明,15例均获得成功。即刻听诊心底部杂音消失,重复主动脉造影,无主动脉腔内狭窄和变形。术后12例即刻无分流,3例有少量残余分流,术后24 h超声心动图示分流消失。肺动脉压术后均有下降。结论:应用成角型蘑菇伞治疗小儿特殊类型PDA适应证范围广,成功率高,治疗效果好。
In order to summarize the experience of using angled mushroom umbrella to seal off patent ductus arteriosus (PDA), the data of 15 children aged 5.5 months to 8 years (average 2.8 ± 2.5 years) were retrospectively analyzed. PDA minimum diameter of 2-10 mm (mean 5.9 ± 3.1 mm), preoperative pulmonary hypertension, mean pulmonary artery pressure of 34-65 mmHg. Selection of new sealing parachute diameter 6-20mm (average 12.9 ± 4.2 mm). The results showed that 15 cases were successful. Instant bottom of the heart auscultation disappeared, repeat aortography, aortic lumen stenosis and deformation. No postoperative shunt in 12 cases, a small amount of residual shunt in 3 cases, shunt disappeared 24 hours after echocardiography. Pulmonary artery pressure decreased after surgery. Conclusion: The application of angled mushroom umbrella in children with a wide range of special type of PDA indications, high success rate, good therapeutic effect.
