Clinical Investigation of Transthoracic Minimally Invasive Patent Ductus Arteriosus Occlusion in Infants and Young Children / 中国循环杂志

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 groupsGroup A, the patients with PDA diameter ≥ 4 mm,n=64 and group B, the patients with 2 mm ≤ PDA diameter 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 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.
