Objectives: After studying the article entitled “Uterine Artery Doppler of the Gravid Uterus as a Predictor Identifying ‘At-Risk’ Pregnancies: A Meta-Analysis,” you will be able to:
Determine the optimum time during pregnancy to document uterine artery spectral Doppler wave-forms and velocities
Document uterine artery spectral Doppler wave-forms for classification
Interpret uterine artery Doppler waveforms and velocities for abnormalities
Uterine artery Doppler is a sonographic tool that aids in isolating __________ pregnancies for adverse outcomes. Low-risk At-risk All Term
The uterine arteries of a gravid uterus undergo a __________ change. Reversed Metabolic Substantial Trophoblastic
A ___________ in the waveform of the gravid uter-ine artery is considered abnormal if detected after the expected time of trophoblastic transition. High velocity Low velocity Diastolic notch Low resistance
Low-resistive blood flow allows perfusion of _________ blood, therefore aiding in fetal development. Oxygenated Deoxygenated Fetal Maternal
RI, PI, and S/D ratio are considered ____________ values used to interpret or categorize waveforms. Negative Quantitative Positive Qualitative
Trophoblastic transition in a normal or “low-risk” pregnancy is generally completed by ____________. Delivery 20 weeks 8 weeks 30 weeks
Pregnancies with conversion of uterine artery Doppler from high-resistance to low-resistance waveforms in the 26th to 28th weeks are considered ___________. Nonviable “Late normalizers” A control group Abnormal
In addition to preeclampsia, there is an increased incidence of __________ in pregnancies with abnormal uterine artery Doppler waveforms. Large for gestational age infants Breech Small for gestational age infants Average-sized infants
“Late normalizers” have an increased risk of _____________. Diabetes Large for gestational age infants Pore-eclampsia Small for gestational age infants
In the first trimester, low values of PP-13 and PAPP-A are indicative of an increased risk of _____________. Diabetes Preeclampsia Normal deliveries Bleeding
