Journal ArticleDOI
Reproductive outcomes in subsequent pregnancies after a pregnancy complicated by open maternal-fetal surgery (1996-2007).
R. Douglas Wilson,Kerrie Lemerand,Mark P. Johnson,Alan W. Flake,Michael Bebbington,Holly L. Hedrick,N. Scott Adzick +6 more
TL;DR: Fertility and gynecologic factors do not appear to be increased for women undergoing OMFS, and the reproductive outcomes of uterine dehiscence and rupture in a subsequent pregnancy continue to be a major counseling issue for OMFS.
Journal Article
Efficacy of transabdominal multifetal pregnancy reduction: collaborative experience among the world's largest centers
Mark I. Evans,Marc Dommergues,Ronald J. Wapner,Lauren Lynch,Yves Dumez,James D. Goldberg,I E Zador,Kypros H. Nicolaides,Mark P. Johnson,M S Golbus +9 more
TL;DR: Multifetal pregnancy reduction is an efficient and safe way of improving outcome in multifetal pregnancies, unambiguously for quadruplets or more, and arguably for triplets, however, particularly at higher starting numbers, there are still suboptimal outcomes.
Journal ArticleDOI
Transabdominal versus transcervical and transvaginal multifetal pregnancy reduction: International collaborative experience of more than one thousand cases
Mark I. Evans,Marc Dommergues,Ilan E. Timor-Tritsch,Ivan E. Zador,Ronald J. Wapner,Lauren Lynch,Yves Dumez,James D. Goldberg,Kypros H. Nicolaides,Mark P. Johnson,Mitchell S. Golbus,Pierre Boulot,Alain J. Aknin,Ana Monteagudo,Richard L. Berkowitz +14 more
TL;DR: Multifetal pregnancy reduction by either method is a relatively safe and efficient method for improving outcome in multifetal pregnancies, and an inverse relationship of starting and finishing number to loss rates and gestational age at delivery suggests that there still is a cost of iatrogenic multifetals pregnancies, even if multifetAL pregnancy reduction can be successfully performed.
Journal ArticleDOI
Diagnosis and characterization of fetal sacrococcygeal teratoma with prenatal MRI.
Enrico Danzer,Anne M. Hubbard,Holly L. Hedrick,Mark P. Johnson,R. Douglas Wilson,Lori J. Howell,Alan W. Flake,N. Scott Adzick +7 more
TL;DR: The results show that ultrafast fetal MRI is a useful adjunct to the prenatal evaluation of fetal sacrococcygeal teratoma and resulted in more accurate prenatal counseling and improved preoperative planning for surgical resection.
Journal ArticleDOI
Perinatal and early surgical outcome for the fetus with hypoplastic left heart syndrome: a 5-year single institutional experience
Jack Rychik,Anita Szwast,Shobha Natarajan,Michael D. Quartermain,Denise Donaghue,Jill Combs,James W Gaynor,Peter J. Gruber,Thomas L. Spray,Michael Bebbington,Mark P. Johnson +10 more
TL;DR: The goal was to establish the benchmark for perinatal and early surgical outcome in the current era, from a center with an aggressive surgical approach and a cohort with a high level of intention‐to‐treat.
