Abstract

BERGANTINI, María L. et al. Ring-sling complex association with pig bronchus: a pediatric case report. Arch. argent. pediatr. [online]. 2022, vol.120, n.3, pp.14-14.  Epub June 01, 2022. ISSN 0325-0075.  http://dx.doi.org/10.5546/aap.2022.e133.

The ring-sling complex is an association between pulmonary artery sling and congenital tracheal stenosis. Pulmonary artery sling is a rare form of vascular ring in congenital heart disease. The clinical case of a child with inspiratory laryngeal stridor associated with respiratory distress is presented, evaluated in another center where respiratory endoscopy was performed, observing extrinsic tracheal compression. Given the clinical suspicion of a vascular ring, CT angiography was requested, confirming the diagnosis of pulmonary artery sling.

He was referred to our hospital and during the surgical intervention a new respiratory endoscopy and tracheobronchography were performed, reaching the diagnosis of congenital tracheal stenosis, right accessory bronchus (pig bronchus) and complete vascular rings, both repaired in the same surgical act.

Keywords : vascular ring; tracheal stenosis; pulmonary artery; bronchi; abnormalities.
