RESUMO
Airway obstruction diagnosed antenatally in the fetus due to congenital high airway obstruction syndrome or nasopharyngeal masses are the primary indications for performing an operation on placental support. Prenatally diagnosed nasopharyngeal masses pose the risk of total airway obstruction upon delivery. Placental support utilises uteroplacental blood flow to facilitate an airway intervention on the fetus while maintaining oxygenation. These interventions must be completed in under 20 min due to amniotic fluid loss and uterine contractions. This case report describes the anaesthetic management of a fetus with a nasal teratoma. In this report, we discuss the clinical indications and anaesthetic considerations of the operation on placental support procedure for nasopharyngeal masses.
