Insights
Congenital complete tracheal rings cause severe long-segment tracheal stenosis in children. Surgical repair using pericardial patch tracheoplasty offers a high survival rate for this life-threatening airway obstruction.
Area of Science:
- Pediatric Surgery
- Thoracic Surgery
- Congenital Airway Malformations
Background:
- Severe tracheal stenosis in infants and children is often caused by congenital complete tracheal rings.
- This condition presents a life-threatening airway obstruction, frequently associated with other congenital anomalies like pulmonary artery slings.
Purpose of the Study:
- To evaluate the outcomes of surgical management for severe tracheal stenosis secondary to congenital complete tracheal rings.
- To assess the efficacy and safety of pericardial patch tracheoplasty as a preferred surgical technique.
Main Methods:
- Management of 23 pediatric patients with severe tracheal stenosis due to congenital complete tracheal rings.
- Surgical repair primarily utilized pericardial patch tracheoplasty with partial cardiopulmonary bypass.
- Bronchoscopy was essential for diagnosis, intraoperative guidance, and postoperative airway management.
Main Results:
- Nineteen out of 23 patients (83%) survived this severe condition.
- Seven survivors also had associated pulmonary artery slings.
- Eighteen patients underwent surgery, with 3 (17%) mortality post-intervention. Mean follow-up was 4.5 years.
Conclusions:
- Pericardial patch tracheoplasty is an effective surgical approach for congenital complete tracheal rings causing long-segment tracheal stenosis.
- Bronchoscopy plays a critical role in diagnosis and long-term management.
- Distal tracheal lesions are linked to increased complications and mortality.
Abstract:
We have managed 23 infants and children with severe tracheal stenosis due to congenital complete tracheal rings producing a long-segment stenosis of the trachea. Nineteen (83%) have survived this life-threatening cause of airway obstruction, 7 of whom also had pulmonary artery slings. Pericardial patch tracheoplasty facilitated by partial cardiopulmonary bypass is currently our preferred technique for surgical repair. Eighteen patients (78%) underwent operative intervention, 3 of whom (17%) have died since surgery. The mean follow-up is 4.5 years. Bronchoscopy is essential for preoperative diagnosis and accurate intraoperative incision of the trachea, and is critical for long-term postoperative airway management. The more distal lesions are associated with increased complications and a higher mortality rate.
