Radical operation on Tetralogy of Fallot and its perioperative outcomes in different ages / 中华实用儿科临床杂志

ABSTRACT

Objective To explore the feasibility and advantages of early open-heart radical operation on infants and children with Tetralogy of Fallot(TOF) in different ages and to analyze its perioperative outcomes.Methods The clinical data of 390 infants and children with TOF were analyzed, who underwent extracorporeal circulation open-heart surgery from January 2007 to January 2014 at the Department of Cardiovascular Surgery,the Third Affiliated Hospital of Zhengzhou University.The operative age ranged from 3 months to 14 years(mean 3 years).There were 172 infants(＜ 1 year old)and 218 children(≥ 1 year old).Some accompanied abnormalities included atrial septal defect (33 cases),patent ductus arteriosus (17 cases),coronary artery anomalies (8 cases), and multiple ventricular septal defect (5 cases).Results Ten patients died, and the overall mortality during hospital stay was 2.56％.The mortality of the infants group and the children group was 2.32％ (4/172 cases) and 2.75 ％ (6/218 cases), respectively,and there was no significant difference (x2 =0.000, P =1.000).Extracorporeal circulation time was (89.16 ± 74.38) min and (83.14 ± 66.72)min, respectively, aortic clamping time was (59.75 ± 35.20) min and (54.70 ± 38.54)min respectively, operation time were (185.34 ± 168.64)min and (163.35 ± 150.15) min respectively, duration of postoperative ventilation were (57.17 ± 67.46) h and (47.50 ± 58.39) h, respectively, the hospitalization time in the Intensive Care Unit was (5.08 ± 7.93) d and (3.71 ± 5.40) d, respectively, and the postoperative stay averaged (13.82 ± 17.78) d and (9.52 ± 8.74) d respectively in the infants group and the children group;there was no significant differences between 2 groups (t =1.937,1.890, 1.991,1.887,1.951,1.931;P =0.259, 0.713, 0.194, 0.739,0.241,0.308).Conclusions The curative effect of early cardiac surgical treatment on infants with TOF is considerably good with low morbidity and mortality.Early cardiac surgical treatment can avoid delayed development and growth in children, hypoxemic spells,sudden death and some other kind of adverse events.
