Comparison between a newly developed PC-based Doppler umbilical artery waveform analyser and a commercial unit.
OBJECTIVES To determine the accuracy of the resistance index (RI) of flow velocity waveforms of the umbilical artery measured using a newly developed PC-based continuous wave Doppler device (Umbiflow) with regard to systematic and random variations when compared with a commercial standard (Vasoflow). DESIGN A cohort study. SETTING The fetal evaluation clinic (FEC) at Tygerberg Hospital. S...
متن کاملOphthalmic artery Doppler waveform in the newborn.
BACKGROUND The ophthalmic artery Doppler waveform (OADW) is thought to correlate with severity of systemic atherosclerosis. The goal of the present study was to evaluate risk of cardiovascular disease (CVD) in newborns small for gestational age (SGA) and appropriate for gestational age (AGA). METHODS AND RESULTS A total of 15 SGA and 26 AGA newborns were enrolled in the study. OADW was compar...
متن کاملDoppler waveform indices of fetal middle cerebral artery in normal 20 to 40 weeks pregnancies.
BACKGROUND One of the main methods for evaluation of fetal well-being is analysis of Doppler flow velocity waveform of fetal vessels. Evaluation of Doppler wave of the middle cerebral artery can predict most of the at-risk fetuses in high-risk pregnancies. In this study, we tried to determine the normal ranges and their trends during pregnancy of Doppler flow velocity indices (resistive index, ...
متن کاملEnd-diastolic Umbilical Artery Doppler Flow Velocity
Doppler velocity measurement has been extensively applied in prenatal diagnosis for more than two decades. Blood flow in numerous vessels has been investigated to predict fetal condition, especially in the umbilical artery [1–7]. Histopathologic studies suggest that abnormal umbilical artery Doppler velocimetry is correlated with a pathologic lesion of the placenta characterized by obliteration...
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...
