Abstract:
Purpose:Bronchopulmonary dysplasia (BPD) is a chronic lung disease that primarily affects premature infants receiving mechanical ventilation and oxygen therapy. Severe BPD leads to long-term respiratory complications, including lung tissue damage, vascular abnormalities, and airway diseases. This study aimed to investigate bronchoscopy findings and characteristics in patients with moderate-to-severe BPD, and to investigate BPD-associated airway diseases.
Methods:A retrospective study of preterm infants diagnosed with moderate-to-severe BPD who underwent bronchoscopic evaluation in the neonatal intensive care unit at Seoul National University Bundang Hospital between 2004 and December 2022 was conducted.
Results:Nineteen patients with a mean gestational age of 28.0±1.6 weeks and mean birth weight of 960.5±271.0 g were included in the study. Among these 19 patients, 18 were diagnosed with severe BPD. Tracheobronchomalacia, laryngomalacia, and subglottic stenosis were observed in 63.2%, 52.6%, and 36.8% of patients, respectively. Tracheostomy was performed in nine of the 19 patients (47.4%); five were discharged without requiring tracheostomy following surgical or medical interventions.
Conclusion:Tracheobronchomalacia, laryngomalacia, and subglottic stenosis were common in patients with moderate or severe BPD who underwent bronchoscopic evaluations, of which 50% required tracheostomy. Our study findings provide valuable insights into the pathophysiology of BPD-associated airway diseases and may inform future clinical management strategies for patients with BPD.
