Fetoplacental biometry and umbilical artery Doppler velocimetry in the overnourished adolescent model of fetal growth restriction.
OBJECTIVE The purpose of this study was to evaluate ultrasonographically fetal growth trajectories, placental biometry, and umbilical artery (UA) Doppler indices in growth-restricted pregnancies of overnourished adolescent ewes and normally developing pregnancies of control-fed ewes. STUDY DESIGN Singleton pregnancies were established using embryo transfer in 42 adolescent ewes that were over...
متن کاملUmbilical artery Doppler velocimetry in the prediction of intrapartum fetal compromise.
The value of early intrapartum umbilical artery Doppler velocimetry in the prediction of fetal compromise was studied. One hundred patients were recruited into the study and fetal compromise was diagnosed by abnormal first- or second-stage fetal heart rate traces, a 5-minute Apgar score less than 7, or the development of hypoxic ischaemic encephalopathy. Fetal compromise developed in 30 patient...
متن کاملFetal Hemodynamic Parameters in Low Risk Pregnancies: Doppler Velocimetry of Uterine, Umbilical, and Middle Cerebral Artery
Objective. To elaborate curves of longitudinal reference intervals of pulsatility index (PI) and systolic velocity (SV) for uterine (UtA), umbilical (UA), and middle cerebral arteries (MCA), in low risk pregnancies. Methods. Doppler velocimetric measurements of PI and SV from 63 low risk pregnant women between 16 and 41 weeks of gestational age. Means (±SD) for intervals of gestational age and ...
متن کاملFetal Doppler: umbilical artery, middle cerebral artery, and venous system.
One of the most important applications of Doppler ultrasonography in obstetrics is the detection of fetal anemia in pregnancies complicated by either red-cell alloimmunization or by other causes of fetal anemia. Doppler of the umbilical artery also has prognostic value in pregnancies affected by twin-twin transfusion syndrome undergoing in-utero intervention. Another potential major application...
متن کاملUmbilical Venous Doppler Velocimetry to Supplement Conventional Arterial Doppler to Assess Third Trimester Fetal Growth Restriction
HKJGOM 2009; 9 (1) 28 Introduction Fetuses born with significant growth restriction have an increased risk of adverse perinatal outcomes1. Moreover, increased perinatal morbidity and mortality was often associated with the presence of abnormal Doppler waveforms in the umbilical arteries (UAs), either in the form of absent or reversed end-diastolic flow2,3. In fetuses with abnormal umbilical art...
