Journal ArticleDOI
Effect of Maternal Betamethasone Administration on Prenatal Congenital Cystic Adenomatoid Malformation Growth and Fetal Survival
William H. Peranteau,R. Douglas Wilson,Kenneth W. Liechty,Mark P. Johnson,Michael Bebbington,Holly L. Hedrick,Alan W. Flake,N. Scott Adzick +7 more
TL;DR: In the fetus with a CCAM, the presence of hydrops fetalis or a CVR >1.6 is indicative of poor fetal outcome without prenatal intervention, and its potential to improve survival in high-risk groups is encouraging and warrants further controlled evaluations.
Journal ArticleDOI
Percutaneous fetal cystoscopy and endoscopic fulguration of posterior urethral valves
Rubén A. Quintero,Roderick F. Hume,Craig Msith,Mark P. Johnson,David B. Cotton,Roberto Romero,Mark I. Evans +6 more
TL;DR: While it is believed that fetal cystoscopy may improve the diagnostic, prognostic, and therapeutic capabilities in the management of fetuses with lower obstructive uropathy, studies are needed to establish the actual value, risks, and limitations of this new approach in fetal medicine.
Journal ArticleDOI
Right congenital diaphragmatic hernia: Prenatal assessment and outcome.
Holly L. Hedrick,Timothy M. Crombleholme,Alan W. Flake,Michael L. Nance,Daniel von Allmen,Lori J. Howell,Mark P. Johnson,R. Douglas Wilson,N. Scott Adzick +8 more
TL;DR: The high incidence of preterm complications, frequent need for ECMO, and high prevalence of comorbidities are indicative of the severity of this CDH population and warrant close prenatal surveillance and delivery at a tertiary care center with ECMO capability.
Journal ArticleDOI
The ex utero intrapartum therapy procedure for high-risk fetal lung lesions
Holly L. Hedrick,Alan W. Flake,Timothy M. Crombleholme,Lori J. Howell,Mark P. Johnson,R. Douglas Wilson,N. Scott Adzick +6 more
TL;DR: The EXIT procedure allows for controlled resection of large fetal lung lesions at delivery, avoiding acute respiratory decompensation related to mediastinal shift, air trapping, and compression of normal lung.
Journal ArticleDOI
Thoracoamniotic shunts: fetal treatment of pleural effusions and congenital cystic adenomatoid malformations.
R. Douglas Wilson,Jason K. Baxter,Mark P. Johnson,Mary King,Stefanie Kasperski,Timothy M. Crombleholme,Alan W. Flake,Holly L. Hedrick,Lori J. Howell,N. Scott Adzick +9 more
TL;DR: Thoracoamniotic shunts should be considered as a treatment option for selected PE or macrocystic CCAM fetuses with hydrops or a significant risk for pulmonary hypoplasia and the neonatal survival with shunting was improved as compared with literature reports.
