Ex utero intrapartum treatment to extracorporeal membrane oxygenation: lifesaving management of a giant cervical teratoma

BackgroundEx utero intrapartum treatment (‘EXIT’ procedure) is a well described method for maintaining maternal–fetal circulation in the setting of airway obstruction from compressive neck masses. When ex utero intrapartum treatment to airway is not feasible, ex utero intrapartum treatment to extracorporeal membrane oxygenation (‘ECMO’) has been described in fetal cardiopulmonary abnormalities.ObjectiveThis paper presents the case of a massively compressive midline neck teratoma managed with ex utero intrapartum treatment to extracorporeal membrane oxygenation, allowing for neonatal survival, with controlled airway management and subsequent resection.Case reportA 34-year-old-female presented with a fetal magnetic resonance imaging scan demonstrating a 15 cm compressive midline neck teratoma. Concern for failure of ex utero intrapartum treatment to airway was high. The addition of the ex utero intrapartum treatment to extracorporeal membrane oxygenation procedure provided time for the planned subsequent resection of the mass and tracheostomy.ConclusionEx utero intrapartum treatment procedures allow for securement of the difficult neonatal airway, while maintaining a supply of oxygenated blood to the newborn. Ex utero intrapartum treatment circulation lasts on average less than 30 minutes. The arrival of extracorporeal membrane oxygenation has enabled the survival of neonates with disease processes previously incompatible with life.
