Objective
The preferred surgical approach for systemic-pulmonary shunts has changed from thoracotomy to sternotomy in our institution, to concomitantly manage the ductus arteriosus during surgery. The purpose of this study was to compare the outcomes of systemic-pulmonary shunts for neonates with functionally univentricular hearts based on surgical approach.
Methods
Fifty-two neonates with functionally univentricular hearts underwent systemic-pulmonary shunt via sternotomy (n = 28) or thoracotomy (n = 24). Patient characteristics, achievement rates of right heart bypass, and survival rates were compared for the different approaches.
Results
Prenatal diagnosis was made more common in the sternotomy group (p = 0.006). The shunt was placed more centrally in the sternotomy group. The ductus arteriosus was ligated or banded in most patients in the sternotomy group (26/28) and in a few patients in the thoracotomy group (6/24). Frequency of ductal management in the early postoperative phase was not different between the groups (21 vs 25 %), but three new incisions had to be made in the thoracotomy group. No differences were seen in the achievement rates of bidirectional cavopulmonary shunts (86 vs 87 % at 10 months of age) and total cavopulmonary connection (81 vs 81 % at 2 years of age), or in the survival rates (92 vs 96 % at 8 years).
Conclusions
There were no differences in short- and long-term outcomes between the groups. The sternotomy approach might be preferable in the current era of prenatal diagnosis, to allow simultaneous duct management during systemic-pulmonary shunt surgery, particularly in patients with large ducts associated with functionally univentricular hearts.
