RESUMO
BACKGROUND: Ex utero intrapartum treatment (EXIT) is utilized for safe delivery when a baby has a compromised airway. The purpose of this retrospective study was to examine the indications and outcomes of 11 children presenting with airway occluding oropharyngeal and cervical teratomas. METHODS: Study of all children with an airway occluding teratoma delivered via EXIT (2001-2018) in our unit. Primary outcomes included survival and tracheostomy at discharge. Data are reported using descriptive statistics as median (range) and rate (%). RESULTS: We performed 45 EXIT procedure performed between January 2001 and April 2018. Of these, eleven were for cervical and/or upper airway teratoma. Ten (91%) cases had associated polyhydramnios, two (18%) developed nonimmune hydrops, and eight (72%) delivered preterm. Six (45.5%) were performed as an emergency. Estimated blood loss was 1000 ml (500, 1000). The neonatal mortality rate was 18% (2/11) and 33% (3/9) of the survivors were discharged with a tracheostomy. CONCLUSION: EXIT is a reasonable option for delivery of babies with an occlusive upper airway mass. Neonatal survival depends on individualized factors but may be as high as 82% in those with teratoma.

A congenital malformation of the head, neck or thorax can lead to upper airway compression with a risk of asphyxia or neonatal death. To secure and protect the upper airway, the Ex Utero Intrapartum Therapy (EXIT) procedure has been developed. The procedure allows delivery of the fetus via a hysterotomy while relying on the placenta as the organ of respiration for the fetus prior to clamping of the umbilical cord. A high level of expertise is necessary for successful completion of the EXIT procedure, which is not void of maternal and fetal risks. In this literature review, we present the indications, procedure methods and materno-fetal complications associated with the EXIT procedure.
