Abstract


Congenital high airway obstruction syndrome (CHAOS) is an extremely rare life-threatening condition. Laryngeal atresia appears to be the most frequent cause. Generally the diagnosis is made with severely enlarged and highly echogenic lungs and additional ultrasound findings. The prognosis of the affected infants is often poor. Five cases are reported here that were diagnosed in a tertiary center between 2008 and 2014.
