Reconstructive surgery for obstructing lesions of the intrathoracic trachea in infants and small children
Insights
Congenital obstructive lesions of the distal trachea and main bronchi in infants can be life-threatening. Surgical reconstruction offers a chance for symptom-free recovery, but outcomes depend on the extent of stenosis.
Area of Science:
- Pediatric Surgery
- Respiratory Medicine
- Congenital Abnormalities
Background:
- Congenital obstructive lesions of the distal trachea and main bronchi present significant challenges in infants.
- Complete cartilage rings in the trachea are a common feature in affected infants.
Observation:
- Ten infants and small children with these conditions were reported.
- Surgical interventions included tracheal resection, bronchoscopic removal of stenosis, and rib splinting for tracheomalacia.
Findings:
- Four infants underwent successful tracheal resection and remain symptom-free.
- One infant with bronchial stenosis improved after bronchoscopic intervention.
- Four infants died due to airway obstruction, two before surgical intervention and two post-operatively due to incomplete stenosis removal.
Implications:
- Early diagnosis and surgical intervention are crucial for managing congenital tracheal and bronchial obstructions.
- Tracheal reconstruction can be successful, but complete removal of stenosis is vital for favorable outcomes.
- Associated conditions, like congenital heart disease, can impact survival despite airway management.
Abstract:
This is a report of ten infants and small children with congenital obstructive lesions of the distal trachea and main bronchi. Four were successfully resected. One with a distal segment stenosis required tracheal resection at age 6 wk, another with stenosis of the distal half of the trachea at age 18 mo, and 2 (1 with distal stenosis and 1 with tracheal hamartoma) at age 4 yr. All 4 are presently free of symptoms and their anastomoses have grown without stricture. A child with coil-spring mucosal stenosis of the left main bronchus developed an excellent airway following bronchoscopic removal of the folds, and a baby with tracheomalacia was successfully treated with a rib splint on a segment of distal tracheomalacia, but she died later of associated cyanotic congenital heart disease. Four babies died with airway obstruction in the newborn period. Two with critical distal stenoses died before tracheal reconstruction could be performed. Two died following emergency resections in which all of the congenital stenosis could not be removed. In both, stenotic trachea remained despite operation. All of these infants had complete cartilage rings the entire length of the trachea. Congenital lesions of the distal trachea may become suddenly life-threatening at birth or during the onset of a respiratory infection. An abrupt or insidious onset of airway symptoms requires an expeditious diagnostic evaluation to define the tracheobronchial anatomy, and the operating team has to be prepared for emergency tracheal reconstruction.
