Pulmonary artery sling with complete tracheal rings in an extremely low-weight premature infant: a case report

This case demonstrates that successful complete repair of complex cardiac and airway anomalies can be achieved in premature, low-weight infants when conventional weight gain thresholds cannot be met. Key factors for success include meticulous surgical technique, precise cardiopulmonary bypass management, careful perioperative care optimisation, and a multidisciplinary approach. While body weight alone should not be an absolute contraindication for surgical intervention, careful patient selection and appropriate institutional expertise are essential.
