A diagnosis of persistent pulmonary hypertension of the newborn should be reviewed if there is a failure to respond to appropriate treatment. We report a case in which both conventional therapy and inhaled nitric oxide failed to break the cycle of right-to-left shunting. Reassessment revealed a massive pulmonary arteriovenous malformation for which surgery was successfully performed in the neonatal period.

We report a patient who developed temporary deafness secondary to oedema of the uvula and soft palate following prolonged continuous positive airway pressure via a nasopharyngeal airway.
