Surgical efficacy of persistent truncus arteriosus in neonates and infants
Objective To evaluate the feasibility and clinical efficacy of non-conduit surgical repair for persistent truncus arteriosus(PTA)in neonates and infants.Methods From July 2011 to November 2022,12 PTA children were recruited.There were 7 boys and 5 girls.Eight children were neonates.Median operative age was 30(8-201)days and median weight 3.3(2.8-5.1)kg.Echocardiography and enhanced computed tomography(CT)were performed.According to the Van Praagh classification scheme,the clinical types were A1(n=6),A2(n=4)and A4(n=2).Right ventricular outflow tract(RVOT)was reconstructed by suturing directly self-pulmonary and right ventricle incision or indirectly with inserting right or left auricle.At the same time,a bovine pericardial patch with valve was applied and other cardiac anomalies were repaired.Results There was no intraoperative mortality.The mean post-discharge follow-up period was(61±36.4)(2-141)months.One child required a second operation due to distal left and right pulmonary artery stenosis while the remainders achieved cardiac function grade Ⅰ/Ⅱ.Conclusion Non-conduit surgical repair for PTA infants is both safe and effective and long-term follow-ups are warranted.
