VA ICU Report – Tracheomalacia

Tracheomalacia Pearls

  • Tracheomalacia can be diagnosed using bronchoscopy or Chest CT w/ inspiratory and expiratory views
  • The most common cause of tracheomalacia in adults is prolonged mechanical ventilation
  • Tracheomalacia can be segmental or diffuse
    • Segmental tracheomalacia can be caused by external pressure on the tracheal wall (e.g. large substernal goiter or a congenital vascular anomaly, such as a right-sided aortic arch w/ aberrant subclavian artery)
    • Diffuse tracheomalacia is encountered in rare conditions like tracheobronchomegaly (Mounier-Kuhn syndrome) or relapsing polychondritis

See the attached CPS case for a great review of tracheomalacia.
