Abstract:
Objective: To investigate the safety and efficacy of transthoracic minimally invasive patent ductus arteriosus (PDA) occlusion in infants and young children.
Methods: We retrospectively analyzed 105 infants and young children who received the transthoracic minimally invasive PDA occlusion in our hospital from 2012-10 to 2014-10. According to PDA diameter, patients were divided into 2 groups:Group A, the patients with PDA diameter ≥ 4 mm,n=64 and group B, the patients with 2 mm ≤ PDA diameter < 4 mm,n=41. All patients received the left third parasternal intercostal incision under suprasternal echocardiography guidance. The operative effect was evaluated by transthoracic echocardiography, and the follow-up study was performed at 1 month, 3 months, 6 months period and then annually after the operation by echocardiography.
Results: All 105 patients had successfully implanted PDA occluders. The patients’ gender, age, body weight, tracheal intubation time and the in-hospital time were similar between 2 groups,P>0.05. Compared with Group B, Group A had the larger diameters of PDA (5.7 ± 1.4) mm vs (2.7 ± 0.6) mm, P<0.001, PDA occluders (10.6 ± 1.8) mm vs (7.2 ± 1.3) mm, P<0.001, and the higher rates of moderate and severe post-operative thrombocytopenia 10.9% (7/64) vs 0% (0/41),P=0.028, immediate post-operative residual shunt as 15.6% (10/64) vs 2.4% (1/41),P=0.031. There was 1 patient in Group A suffered from pericardial tamponade due to hemorrhage at 2 days after operation and he was cured by emergent pericardial drainage. The patients were followed-up for (11.6 ± 7.8) months. The 1 month post-operative residual shunt was similar between 2 groups as 1.6% (1/64 ) vs 0% (0/41),P=0.421, and there was no residual shunt at 3 months after the operation. There were no complications of occluder detachment, hemolysis, pericardial effusion, left pulmonary artery or descending aortic stenosis occurred during the follow-up period.
Conclusion: Transthoracic minimally invasive PDA occlusion is a safe and effective method to treat the relevant infants and young children, while the post-operative residual shunt and thrombocytopenia should be closely observed in patients with large PDA.
