    AbstractNeonates with necrotizing tracheobronchitis present a diverse clinical spectrum from asymptomatic disease to severe airway obstruction. A retrospective clinicopathologic study of 206 neonatal autopsy reports spanning a three-year period yielded 122 cases of necrotizing tracheobronchitis with an incidence of 59%. All study patients received treatment prior to the development of high-frequency ventilator jet, oscillator, or interruption. The site and submucosal depth of airway involvement was variable. The most commonly affected anatomic site was the middle or thoracic trachea (56%). The common cause identified was severe ischemia to the airway mucosa and submucosa, occurring with profound birth asphyxia and/or shock. The presence of ischemia supports the concept that decreased tracheoperfusion may be an important factor in the development of tracheobronchial abnormalities.
