BackgroundWe reviewed our experience to determine the role of endoscopic airway stents in children with tracheobronchial obstruction.MethodsSeventeen children (10 boys and 7 girls) aged 2 months to 16 years underwent tracheobronchial stenting. Etiology of the tracheobronchial obstruction included external vascular compression (n = 9); tracheobronchial anastomotic strictures after heart-lung/lung transplantation (n = 4); airway compression by malignant mediastinal mass (n = 2), and subglottic/high tracheal stenosis after prolonged intubation with a tracheostomy in situ (n = 2). Indications for airway stenting were failure to wean from ventilator after a mean of 82.5 days (range, 2 to 210) in 8 children; and dyspnea or stridor in the remaining 9 children.ResultsTen children had a total of 24 uncovered self-expanding metal stents (either Magic Wallstent or Ultraflex Microvasive) and 7 children had silicone stents (2 straight, 3 Y and 2 T tube stents). At follow-up at 1 week to 72 months (median 21), only 8 of 17 (47%) children were alive but all the deaths were secondary to the underlying pathology and not related to tracheobronchial stenting. Six of 8 ventilator-dependent children were extubated after a mean of 5.3 days (range, 2 to 11) after airway stenting. For the 9 children stented for dyspnea, mean Medical Research Council dyspnea score decreased from 3.0 to 1.6 after stenting.ConclusionsTracheobronchial stenting in children is only rarely needed and often undertaken in dire circumstances. The procedure has led to significant symptomatic benefit in dyspneic children and has enabled ventilator-dependent children to be extubated. Medium-term outlook after stenting with self-expanding metal stents for vascular compression of the airway is encouraging. The long-term outcome remains uncertain, however, and is ultimately influenced by the underlying disease.
