Double trouble: prolapsing epiglottis and unexpected dual pathology in an infant

Abstract

A 3-week-old full-term female neonate was admitted with a 4-day history of episodic stridor, desaturations and difficult feeding. Initial assessment using fluoroscopy suggested distal tracheomalacia. Inhalational induction for examination under anaesthesia of the upper airway at 4 weeks of age caused almost complete airway obstruction due to severe anterior, or epiglottic, laryngomalacia. This airway obstruction was unresponsive to continuous positive airway pressure, the use of an oropharyngeal airway and hand ventilation and required urgent tracheal intubation using suxamethonium. Epiglottopexy, a relatively unknown procedure, was performed uneventfully 2 days later, with complete relief of the respiratory compromise. However, the infant remained desaturated postoperatively. A ventilation perfusion scan subsequently revealed multiple pulmonary arteriovenous malformations, unsuitable for embolization and requiring nocturnal home oxygen therapy. Review at 3 months of age found a thriving infant with no airway obstruction and good epiglottic positioning on examination under anaesthesia. Although the patient's oxygen requirements had diminished, the long-term outcome remains uncertain.
