Cesarean section with operation on placental support as an adapted EXIT procedure for fetal thyroid goiter: A case report and literature review.

Abstract

The ex-utero intrapartum treatment (EXIT) procedure is a specialized delivery strategy that extends utero-placental-fetal circulation to convert a potential neonatal emergency condition into a condition that is compatible with postnatal life. Cesarean section with operation on placental support is an EXIT technique that requires a relatively short duration of placental support and few skilled medical personnel and specialized instruments; it can successfully treat selected fetal indications. In the present study, we report a case of fetal thyroid goiter as an example of a fetal anomaly requiring the procedure. We then review all cases published in the medical literature that were similar to our procedure (15 cases including our new case). Twelve (80%) cases of fetal anomalies and three prophylactic cases of extremely low birth weight were delivered using a procedure adapted from the standard EXIT procedure. All 12 cases of fetal anomalies were treated by airway intervention. In 12 of the 15 cases (80%), direct laryngoscopy and endotracheal intubation were attempted; intubation was successful in seven of these 12 cases (58%). There was only one case of postpartum hemorrhage caused by uterine incisional bleeding, with a consequence of delayed hysterotomy closure. In summary, cesarean section with operation on placental support is a promising alternative delivery technique for neonates with airway obstructive lesions, especially in resource-limited settings.
