Fetal Endoscopic Tracheal Intubation: Modification of the Fetal Endoscopic Tracheal Intubation Procedure to Establish an Airway in a Fetus with a Congenital Cervical Teratoma

Introduction: FETI is a technique where the fetal airway is secured in-utero via intubation by percutaneous endoscopic fetal tracheoscopy under ultrasound guidance. FETI has been described in large fetal neck masses with anatomical airway compression as a feasible airway management strategy and a potential alternative to an EXIT procedure in select cases. Case Presentation: This report describes the use of a modified FETI procedure under continuous fetoscopic and ultrasound guidance, in a fetus with a large cervical teratoma causing airway displacement and compression. Following the FETI procedure, an uncomplicated caesarean section was performed. The endotracheal tube was in place at the time of birth, and a patent airway was confirmed. Conclusion: The modified FETI procedure described in this report represents another technique that can be used to establish an airway in fetuses with challenging upper airway anatomy, potentially mitigating the risks associated with an EXIT procedure.
