Abstract

Objective: In this study, patients who were operated for Tetralogy of Fallot were evaluated in terms of the influence of age at operation on early morbidity and mortality. Material and Methods: 94 patients who had undergone total correction for Tetralogy of Fallot between 2007 and 2010 were evaluated retrospectively. The patients were divided into two groups. Group I (n=40) consisted of patients younger than 12 months, Group II (n=54) consisted of patients older than 12 months. The mean age in Group I and II were 8.4±2.8 months and 19±3.9 months, respectively. Results: The mean length of stay in intensive care unit were 5.3±9 days, in Group I and 3.4±3 days in Group II (p<0.05). The mean aortic cross clamp and total cardiopulmonary bypass times were 67±16 and 98±34 minutes in Group I, whereas they were 76±27 and 105±40 minutes in Group II, respectively. There was no statistical difference between two groups. Coronary arterial abnormalities were present in 9 (10.4%) patients. Among those, total correction operation was performed without conduits in 3 (33%) and conduits were used in the remaining 6 (66%) patients. The early hospital mortalities were 5% (n=2) in Group I and 3,7% (n=2) in Group II, respectively. The difference between two groups was statistically insignificant. Conclusion: No difference in morbidity and mortality rates except length of intensive care unit stay were detected between two groups. In order to prevent the deleterious effects of hypoxia and provide normal organ development, the operation should be performed as possible as early. Because early operative age does not increase the mortality. Copyright © 2012 by Türkiye Klinikleri.
