Journal ArticleDOI
Ex utero intrapartum treatment (EXIT) in the management of cervical lymphatic malformation.
Pablo Laje,William H. Peranteau,Holly L. Hedrick,Alan W. Flake,Mark P. Johnson,Julie S. Moldenhauer,N. Scott Adzick +6 more
TL;DR: The EXIT procedure allows controlled airway access in fetuses with cervical lymphatic malformations and evidence of airway impairment on prenatal images is found.
Journal ArticleDOI
Chorioamniotic membrane separation following open fetal surgery: pregnancy outcome.
R. Douglas Wilson,Mark P. Johnson,Timothy M. Crombleholme,Alan W. Flake,Holly L. Hedrick,Mary King,Lori J. Howell,N. Scott Adzick +7 more
TL;DR: Membrane separation post hysterotomy may be associated with an increased risk of PROM but not delivery before 30 weeks gestation, while elective delivery at 36–37 weeks gestation was possible for 43% of the fetal surgery population.
Journal ArticleDOI
Fetal head biometry assessed by fetal magnetic resonance imaging following in utero myelomeningocele repair.
Enrico Danzer,Mark P. Johnson,Michael Bebbington,Erin M. Simon,R. Douglas Wilson,Larrissa T. Bilaniuk,Leslie N. Sutton,N. Scott Adzick +7 more
TL;DR: Mid-gestational repair of MMC promotes normalization of extra-axial CSF spaces and Restoration of CSF volume in the posterior fossa after in utero repair is indicative of reversal of hindbrain herniation.
Journal ArticleDOI
Fetal ventriculomegaly: Diagnosis, treatment, and future directions
Jared M. Pisapia,Saurabh Sinha,Deborah M. Zarnow,Mark P. Johnson,Gregory G. Heuer,Gregory G. Heuer +5 more
TL;DR: Diagnosis, work-up, counseling, and management strategies as they relate to fetal VM, as well as imaging-based research efforts aimed at using prenatal data to predict postnatal outcome, are described.
Journal ArticleDOI

Andrea T. Badillo,Holly L. Hedrick,R. Douglas Wilson,Enrico Danzer,Michael Bebbington,Mark P. Johnson,Kenneth W. Liechty,Alan W. Flake,N. Scott Adzick +8 more
TL;DR: In the setting of gastroschisis, isolated findings of gastrointestinal abnormalities on prenatal ultrasound do not correlate with adverse postnatal outcome.
