External Stenting for Bronchomalacia Involving the Bronchus Intermedius

Area of Science:

• Pediatric Pulmonology
• Thoracic Surgery
• Medical Device Technology

Background:

• External stenting is established for proximal airway compression (trachea, main bronchi) in children.
• Limited evidence exists for external stenting in distal airway conditions like bronchomalacia.
• Absent pulmonary valve syndrome can be associated with complex airway anomalies.

Observation:

• A 1-year-old girl with absent pulmonary valve syndrome presented with recurrent respiratory infections.
• Bronchomalacia of the bronchus intermedius was diagnosed as the underlying cause.
• The patient underwent successful external stenting of the affected airway segment.

Findings:

• Postoperative resolution of recurrent respiratory infections was observed.
• The external stenting procedure demonstrated short- and mid-term safety.
• The intervention proved effective in managing distal bronchomalacia.

Implications:

• External stenting is a viable treatment option for distal airway malacia, specifically the bronchus intermedius.
• This case expands the application of external stenting to previously underreported airway segments.
• Further research into external stenting for pediatric distal airway diseases is warranted.
