Abstract:
Objective:To study the early outcomes of emergency operation employed with one of the prevalent surgical methods in neonates diagnosed as pulmonary atresia with intact ventricle septum(PA/IVS) and critical pulmonary stenosis(CPS), and to analyze the risk factors related to its early results.Methods:A retrospective analysis was conducted to collect the data of neonates suffered from PA/IVS and CPS from January 2016 to January 2020 in cardiothoracic surgery department at Shanghai Children′s Medical Center.According to their Z score, which reflects the development degree of right ventricle, the neonates received one of the relevant popular operations.Early outcomes were summarized and risk factors related to its early stage mortality were analyzed.Results:A total of 65 neonates were enrolled, including 27 CPS cases.They were operated on the basis of their respective Z scores, and also according to these data, the primary surgical procedure was chosen from the following methods: Blalock-Taussig(B-T) shunt, pulmonary valvulotomy and right ventricular outlet enlargement.Totally seven cases died, and mortality was 10.7%.Nine cases received re-operation in several following days because of severe hypoxemia and low cardiac output.All patients had mild improvement in oxygen saturation after operation and relied on large dose of inotropic agent.Multivariate Logistic regression analysis showed that B-T shunt and re-operation in early period were risk factors for death in neonates with PA/IVS and CPS.Conclusion:There is a higher mortality in neonates who received emergency operation for PA/IVS and CPS.Accurate assessment of the right ventricle development degree and selecting the corresponding appropriate surgical method is critical for the optimal result.B-T shunt and early stage re-operation are the risk factors for death in neonates with PA/IVS and CPS who received emergency operation.
