Journal ArticleDOI
A Randomized Trial of Prenatal versus Postnatal Repair of Myelomeningocele
N. Scott Adzick,Elizabeth Thom,Catherine Y. Spong,John W. Brock,Pamela K. Burrows,Mark P. Johnson,Lori J. Howell,Jody A. Farrell,Mary E. Dabrowiak,Leslie N. Sutton,Nalin Gupta,Noel Tulipan,Diana L. Farmer +12 more
TL;DR: Prenatal surgery for myelomeningocele reduced the need for shunting and improved motor outcomes at 30 months but was associated with maternal and fetal risks and increased risk of preterm delivery and uterine dehiscence at delivery.
Journal ArticleDOI
Cystic adenomatoid malformation volume ratio predicts outcome in prenatally diagnosed cystic adenomatoid malformation of the lung
Timothy M. Crombleholme,Beverly G. Coleman,Holly L. Hedrick,Kenneth W. Liechty,Lori J. Howell,Alan W. Flake,Mark P. Johnson,N. Scott Adzick +7 more
TL;DR: The authors report the results of prospective use of the CVR both to track tumor growth and regression during gestation and confirm its predictive value in fetuses with CAM, suggesting its usefulness as a predictor of outcome in CAM.
Journal ArticleDOI
Improvement in hindbrain herniation demonstrated by serial fetal magnetic resonance imaging following fetal surgery for myelomeningocele.
Leslie N. Sutton,N S Adzick,Larissa T. Bilaniuk,Mark P. Johnson,Timothy M. Crombleholme,Alan W. Flake +5 more
TL;DR: In this series of patients, fetal myelomeningocele closure resulted in improvement in hindbrain herniation as demonstrated by serial MRI scans.
Journal ArticleDOI

Sarah Bouchard,Mark P. Johnson,Alan W. Flake,Lori J. Howell,Laura B. Myers,N. Scott Adzick,Timothy M. Crombleholme +6 more
TL;DR: The EXIT procedure was used successfully to ensure uteroplacental gas exchange and fetal hemodynamic stability during a variety of surgical procedures performed to secure the fetal airway or ensure successful transition to postnatal environment.
