title: EXIT procedure in a twin gestation and review of the literature.
abstract: Prenatal diagnosis can show masses of the fetal neck, mouth, and face that can potentially cause respiratory distress at birth. To prevent such an emergency, the EXIT (ex utero intrapartum technique) is performed: it is the intrapartum intubation of the fetus at term while still connected to the placenta. The EXIT procedure was first performed in a case of cervical teratoma. Up to now a total of 34 cases are described, mostly cervical teratomas (13 cases), lymphangiomas (7), epignathus (3); babies' outcome has been successful in 25 of them, with one death related to the procedure. Among the reported cases we are aware of only one where EXIT was performed in a twin gestation, in which the normal twin was delivered first. In our case the normal fetus was posterior to the twin with cervical malformation, requiring us to work on the latter while the former was still in the uterus. After having safely secured the airway in twin A, twin B was prompt delivered with excellent general conditions. Our limited experience enlarges the possibility to perform this prenatal procedure even in "nonstandard" conditions, such as a twin gestation, and may prove useful to those who are going to deal with such issues.
