A rare congenital heart defect, left pulmonary artery sling, caused breathing issues and lung infections in a young boy. Surgical correction successfully resolved these symptoms, highlighting the importance of early diagnosis and intervention.

Area of Science:

  • Pediatric Cardiology
  • Thoracic Surgery
  • Congenital Cardiovascular Anomalies

Background:

  • Left pulmonary artery sling is a rare congenital anomaly where the left pulmonary artery arises from the right pulmonary artery and passes between the trachea and the esophagus.
  • This anatomical variation can lead to extrinsic compression of the airway, particularly the distal trachea.

Observation:

  • A two-year-old boy presented with persistent stridor since birth and recurrent pulmonary infections.
  • Diagnostic imaging revealed mechanical compression of the distal trachea, indicative of a left pulmonary artery sling.

Findings:

  • The case details the diagnostic pathway and surgical management of this rare condition.
  • Surgical intervention successfully relieved the tracheal compression and resolved the patient's symptoms.

Implications:

  • This case underscores the importance of considering rare vascular anomalies in the differential diagnosis of pediatric airway obstruction.
  • Early diagnosis and surgical correction of left pulmonary artery sling can lead to favorable outcomes in affected children.
  • This report contributes to the limited literature on pulmonary artery sling, being the first in Brazil and fifth in a Latin language country.
