Clinical outcomes of ex utero intrapartum treatment for fetal airway obstruction

摘要

PurposeThe aim of this study was to evaluate the indications and the clinical outcomes of the fetuses managed with ex utero intrapartum treatment (EXIT) procedures.MethodsWe retrospectively reviewed the medical records of all fetuses who underwent EXIT procedures between 2003 and 2018.ResultsEXIT procedures were performed in nine cases. The prenatal diagnosis of the neonates was congenital high airway obstruction syndrome in four cases, the neck masse in five cases. Although the airway management under the EXIT procedure was successful in eight cases, the airway management failed in one case. During the EXIT procedures, the airway was managed by endotracheal intubation in two cases, whereas six cases underwent tracheostomy. Six cases with fetal airway obstruction survived to discharge, whereas three cases died due to airway management failure or complications of the underlying disease. A case with a cervical teratoma underwent tumor resection the day after birth due to rapid enlargement of the neck mass. Long-term survival was achieved in five cases.ConclusionsWe concluded that the EXIT procedure was effective and could be performed safely in the airway management of fetuses with suspected airway obstruction. The treatment strategy for the neck masses should be planned before birth.
