Venous Doppler in the Evaluation of Fetal Hydrops
Objective. To examine venous blood flow velocity in different types of fetal hydrops and its value in the prediction of outcome of pregnancies. Methods. Venous Doppler sonography was performed in 100 hydropic fetuses from 15 to 37 weeks of gestation. Blood velocity was recorded in the right hepatic vein (HV), the ductus venosus (DV) and in the intra-abdominal part of the umbilical vein (UV). Bl...
متن کاملDoppler velocimetry of normal human fetal venous intrapulmonary branches.
OBJECTIVES To describe the nature of flow velocity waveforms from fetal middle and distal venous pulmonary branches in the second half of normal pregnancy in relation to gestation, and to test repeatability and interrelationships of flow velocity waveform recordings from proximal, middle and distal venous pulmonary branches. DESIGN Cross-sectional study. SUBJECTS/METHODS A total of 111 norm...
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...
متن کاملSex Specific Differences in Fetal Middle Cerebral Artery and Umbilical Venous Doppler
BACKGROUND The incidence of several adverse pregnancy outcomes including fetal growth restriction are higher in pregnancies where the fetus is male, leading to suggestions that placental insufficiency is more common in these fetuses. Placental insufficiency associated with fetal growth restriction may be identified by multi-vessel Doppler assessment, but little evidence exists regarding sex spe...
