Summary
Congenital tracheal stenosis, a rare anomaly, can be life-threatening. Endoscopic balloon dilatation offers a less invasive treatment option, improving airway obstruction in children with long-segment stenosis.
Area of Science:
- Pediatric Surgery
- Pulmonology
- Medical Devices
Background:
- Congenital tracheal stenosis is a rare but serious condition with high mortality.
- Existing surgical treatments like resection and tracheoplasty have limitations and significant morbidity.
- Long-segment tracheal stenoses pose a particular challenge for effective treatment.
Observation:
- Four children with critical airway obstruction due to long-segment tracheal stenosis were treated.
- Symptoms included respiratory distress, stridor, and chest retractions, with stenoses located in various tracheal segments.
- Bronchoscopic evaluation revealed severely narrowed lumens (≤1 mm in three patients).
Findings:
- Endoscopic balloon dilatation using Gruentzig catheters (3-8 mm) was performed.
- Dilatation resulted in a posterior split of complete tracheal rings, significantly increasing airway lumen.
- All treated children showed improvement; three remain well over 3 years post-procedure.
Implications:
- Endoscopic balloon dilatation is a promising, less invasive alternative for managing congenital tracheal stenosis.
- This technique can provide significant and durable improvement in airway obstruction.
- Further research may explore its application in various tracheal anomalies and long-term outcomes.
