The ex utero intrapartum treatment (EXIT) procedure in giant fetal neck masses.

Giant fetal neck masses can cause airway obstructions with potential poor fetal prognosis after delivery. The relationship between the fetal neck mass and airway structure can be defined prenatally with ultrasound and magnetic resonance imaging (MRI). The ex utero intrapartum treatment (EXIT) procedure is an available technique to obtain a fetal airway while feto-maternal circulation is preserved. We present a case in which prenatally a giant fetal neck mass was diagnosed on ultrasound and MRI, and a successful EXIT procedure could be performed. Copyright (c) 2005 S. Karger AG, Basel.
