EARLY OUTCOMES OF EXTRACARDIAC FONTAN SURGERY AT HANOI HEART HOSPITAL PERIOD OF 2017 - 2022
Main Article Content
Abstract
Objective: To assess the outcomes of Fontan surgery erformed at Hanoi Heart Hospital. Methods: This retrospective study involved 80 pediatric patients diagnosed with single-ventricle congenital heart disease who underwent Fontan procedures. Results: The average duration of postoperative mechanical ventilation was 87.3 hours, and the mean oxygen saturation after surgery was 89.47%. Among the observed complications, acute kidney injury was the most prevalent at 37.5%, followed by bleeding at 16.25%, and chylothorax at 15.0%. The average cardiopulmonary by pass time was 166.81 minutes, while the mean aortic cross-clamp time among 45 patients was 60.73 minutes, with the shortest recorded time being 10 minutes. Conclusion: The findings highlight that the age of patients at the time of Fontan surgery plays a crucial role in outcomes, with older patients being at higher risk. Postoperative complications such as acute kidney injury, bleeding, mediastinitis, and cerebrovascular events continue to present significant challenges in the postoperative period.
