Fontan procedure on deep hypothermic circulatory arrest: Short-term results and technique
Background : Various operative strategies are described for the Fontan procedure. In this study, we describe our short-term results and technique of Fontan procedure on cardiopulmonary bypass (CPB) and deep hypothermic circulatory arrest (DHCA).
Methods : This was a retrospective study of 32 patients, median age of 6 years (4β19 years) and median weight of 20 kg (13β51 kg), who underwent Fontan procedure on CPB and DHCA from July 2016 to July 2021.
Results : The median CPB time was 125 min (77β186 min), the median DHCA time was 42 min (27β50 min), and the median Fontan pressure was 14 mmHg (10β18 mmHg). The median time to extubation was 4 h (1β20 h), the duration of chest tube drainage was 8 days (5β24 days), and the median intensive care unit stay was 4 days (3β8 days). The presence of heterotaxy was associated with longer duration of pleural drainage (P = 0.01). There was no operative mortality and no major adverse events such as seizures, gross neurological deficits, or arrhythmias in the postoperative period.
Conclusions : Fontan procedure can be safely performed on CPB and DHCA with good operative results. This operative strategy may be used in special circumstances like in patients with situs and systemic venous anomalies and those requiring repair of a complex intracardiac defect. Long-term follow-up will be required to evaluate if this strategy has any impact on the neurodevelopmental outcome and the long-term sequelae of Fontan
