The interval between the preparatory operation and catheter procedure was 7 months (range 6\u20139). Median procedure time was 140 minutes (range 120\u2013180). The ICU stay was 2 days (range 1\u20133), and the total hospital stay was 5 days (range 4\u20136). Minimal pleural effusions occurred in four patients, none requiring drainage. At a median follow-up of 28 months (range 4\u201336), all patients were clinically stable; resting oxygen saturation was 96% (range 94% to 97%). One late-presenting patient had biochemical evidence consistent with protein-losing enteropathy but remained asymptomatic without targeted therapy. No thromboembolic events occurred.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S1047951125110998_as4\">\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>In a programme that couples surgical preparation with later catheter-based completion, the extracardiac Fontan can be performed safely and effectively in carefully selected candidates, with rapid recovery and stable mid-term clinical status.
