Outcomes of surgical repair of congenital vascular rings in children

The results show that surgical repair of congenital vascular rings in pediatric patients yields excellent outcomes: most patients' symptoms improved and only a small proportion required reintervention. Although the pulmonary artery sling forms an incomplete vascular ring, it is associated with a higher incidence of tracheal stenosis and an increased risk of persistent postoperative respiratory symptoms. These observations suggest that more proactive intraoperative management of tracheal stenosis should be considered during the primary operation.
