The Fontan procedures – early outcomes and predictive factors
Main Article Content
Abstract
Objectives: the aim of this study was to describe the early outcomes after the extracardiac conduit Fontan procedure and evaluate predictive factors related to these results.
Methods: a cross – sectional study. We retrospectively reviewed the perioperative medical records of 71 patients with Fontan surgery at Hanoi Heart Hospital between January 2017 and December 2020. Data processing using SPSS 22 software
Results: the early mortality and early failure rates with Fontan circulation were 4.2%. High postoperative pulmonary artery pressure was a risk factor for early mortality and early Fontan failure. The mean duration of mechanical ventilation was 62.86±108.17 hours; female, short height, and common atrioventricular valve or doubleinlet atrioventricular connection increased the risk of prolonged mechanical ventilation. The mean intensive care unit (ICU) length of stay was 6.46±6.32 days, female, short height, and moderate to severe postoperative atrioventricular valve regurgitation increased the risk of prolonged duration in ICU. The mean time of pleural drainage was 16.96±10.23 days, low weight was a risk factor for prolonged pleural drainage. The mean postoperative hospital stay was 23.89±11.83 days, age at the Fontan surgery, preoperative oxygen saturation, concomitant atrioventricular valve repair, and postoperative atrioventricular valve regurgitation were factors associated with prolonged postoperative hospital stay.
Conclusion: the early outcomes after Fontan surgery have been consistent with our condition. There have been many risk factors that influenced early results after surgery, and identifying those factors may help with our treatment.
