Background:
As the surgical treatment of scoliosis after a Fontan procedure is very challenging due to the risk of various perioperative complications, case reports are scarce. We herein describe three patients who were successfully treated for scoliosis following a Fontan procedure and discuss their clinical and radiological outcomes.
Methods:
We retrospectively reviewed three cases of scoliosis treated by posterior spinal fusion after a Fontan procedure.
Results:
Mean preoperative major curve Cobb angle was 83.7°, mean surgical time was 233.0 min, and mean blood loss was 1167 g. The mean correction rate of the major curve was 48.0%. Surgical outcome as evaluated by Scoliosis Research Society-22 patient questionnaires revealed acceptable results without any severe complications.
Conclusions:
Corrective surgery for scoliosis after a Fontan procedure becomes a stronger option if cardiac insufficiency is prevented during the perioperative period and a conservative plan is carried out with minimal invasiveness and operation time.
