Research entitled “Perinatal Outcomes With Normal Compared With Elevated Umbilical Artery Systolic-to-Diastolic Ratios in Fetal Growth Restrictions,” has been published in the April issue of Obstetrics & Gynecology. The research was led by, Drs. Lindsay Maggio and Catherine Albright, fellows from the Department of Maternal-Fetal Medicine (MFM) at Women & Infants Hospital of Rhode Island and The Warren Alpert Medical School of Brown University; Drs. Joshua D. Dahlke and Hector Mendez-Figueroa, former MFM fellows; and Dr. Katharine Wenstrom, director of the Division of Maternal-Fetal Medicine (MFM) and co-director of the Integrated Program for High-Risk Pregnancy at Women & Infants Hospital, and a professor of obstetrics and gynecology at the Alpert Medical School, along with Suneet P. Chauhan from the University of Texas Medical School at Houston.

The group examined the delivery of growth restricted fetuses with elevated umbilical artery Dopplers at 37 weeks and those with normal Dopplers at 39 weeks. Umbilical Artery Doppler is an ultrasound test that measures blood flow through the umbilical artery, and thus indirectly assesses resistance to blood flow in the placenta. Delivering a growth restricted fetus with elevated Dopplers at 37 weeks resulted in successful outcomes that were similar to those of growth restricted fetus with normal Dopplers delivered at 39 weeks, whether by vaginal birth or by cesarean.

Dr. Maggio explains that these findings are incredibly important when it comes to the suggested management of fetuses with elevated Dopplers. “There are no studies that provide data to guide how Doppler tests should be used to direct delivery management of fetuses with growth restriction. Our study shows that delivering fetuses with elevated Dopplers at 37 weeks results in good neonatal outcomes. Prior to this study, management for this particular scenario was based mostly on expert opinion,” said Dr. Maggio.

The researchers concluded that “planning delivery of pregnancies with fetal growth restriction and elevated systolic-to-diastolic ratios and without other complications at 37 weeks of gestation results in good outcomes.”
