Assessment of the Number of Umbilical Cord Vessels at the Time of Nuchal Translucency Screening
In Brief
An observational study evaluating Doppler ultrasound for Umbilical Cord. Completed, enrolled 123 participants across 2 sites.
Detailed Summary
The primary objective of this study is to determine the detection rate of two- or three-vessel umbilical cord at the time of nuchal translucency screening between 11 and 13 6/7 weeks gestation. Hypothesis: Detection rate of the number of vessels during first trimester will be as accurate as the detection of vessels during the second trimester.
