| Popis: | Background: Several factors affect the long-term outcome of Fontan procedure, but a high pulmonary artery pressure is still one of the most important limitation for proceeding to a Fontan circulation. Herein, we present our experience in Fontan patients with high preoperative pulmonary artery pressures. Methods: A retrospective analysis was performed in order to evaluate Fontan patients with a preoperative pulmonary artery pressure > 15 mmHg between 2009 and 2020. Sixteen patients were operated on with a mean preoperative pulmonary artery pressure of 17.5 ± 2.1 mmHg. Results: Mean age at the time of Fontan procedure was 7.8 ± 5.6 years. All of the patients had stage II cavopulmonary anastomosis prior to Fontan completion, with a mean interstage period of 4 ± 2.6 years. Fontan completion was achieved with a polytetrafluorethylene (PTFE) tubular conduit, two of which were intra-extracardiac. Fenestration was performed in 4 (25%) cases. Postoperative pulmonary artery pressures and arterial oxygen saturation levels were 11.2 ± 2.8 mmHg and 97.8 ± 2, respectively. Mean duration of pleural drainage was 3.9 ± 5.3 days. Any morbidity and mortality were not encountered during a mean follow up period of 4.8 ± 7.7 years. Conclusions: The mid-term results of stage III Fontan completion in patients with pulmonary artery >15 mmHg are encouraging. Pulmonary vascular resistance, not only pulmonary artery pressure may help to identify high risk patients before Fontan completion. |
