Pulmonary sling. Case report and collective review

Area of Science:

• Cardiology
• Pediatric Surgery
• Congenital Heart Disease

Background:

• Anomalous left pulmonary artery arising from the right pulmonary artery is a rare congenital defect.
• This anomaly presents with specific infant symptoms including expiratory stridor and esophageal indentation.
• Lethal progression within the first year of life is characteristic of this condition.

Purpose of the Study:

• To report the eighteenth successful surgical correction of this rare pulmonary artery anomaly.
• To highlight the first documented case of confirmed left pulmonary artery patency post-surgery.
• To review previously reported cases and surgical outcomes.

Main Methods:

• Surgical correction via left thoracotomy.
• Division of the proximal left pulmonary artery.
• Implantation of the left pulmonary artery into the main pulmonary artery.

Main Results:

• Successful surgical outcome in the eighteenth reported case.
• Demonstrated patency of the left pulmonary artery via postoperative angiography.
• Review of previous surgical interventions and outcomes for this anomaly.

Conclusions:

• Surgical correction through left thoracotomy is an effective treatment.
• Maintaining left pulmonary artery patency is achievable and crucial for survival.
• This case adds to the limited but growing body of evidence for successful surgical management.
