Congenital lobar emphysema and sequestration--treatment by embolization

Area of Science:

• Pediatric Surgery
• Thoracic Surgery
• Neonatal Respiratory Medicine

Background:

• Congenital lobar emphysema (CLE) is a rare neonatal condition characterized by overinflation of a lung lobe.
• Pulmonary sequestration (PS) is a congenital abnormality where lung tissue lacks normal bronchial connections.
• The co-occurrence of CLE and PS is exceptionally uncommon, presenting unique diagnostic and therapeutic challenges.

Observation:

• A neonate presented with severe respiratory distress attributed to CLE.
• Imaging revealed associated vascular sequestration in the ipsilateral lower lobe.
• The clinical presentation necessitated urgent intervention due to the severity of respiratory compromise.

Findings:

• Emergency lobectomy successfully addressed the hyperinflation of the affected lobe in CLE.
• Therapeutic embolization was employed to manage the vascular supply of the pulmonary sequestration.
• This combined approach preserved lung function and avoided extensive resection.

Implications:

• This case highlights a successful strategy for managing the rare co-existence of CLE and PS.
• Salvaging lung tissue through embolization minimizes long-term morbidity associated with pneumonectomy in infants.
• This approach offers a potential alternative for similar complex congenital thoracic anomalies.
