US pregnant uterus 9 Assessment of fetal measurement, growth, amniotic fluid, fetal anatomic survey, and activity patterns is appropriate. O US pregnant uterus biophysical profile 4 Assessment of biophysical profile is of indeterminate appropriateness. Biophysical profile components: 1) fetal heart-rate reactivity; 2) fetal breathing movements; 3) fetal movement; 4) fetal tone; and 5) amniotic ...

INTRODUCTION It is estimated that 3-10% of infants are growth restricted. Growth disturbances may have long-term issues. Doppler allows insight into the fetal response to intrauterine stress. OBJECTIVE The aim of this study was to detect fetal compromise in intrauterine growth-restricted (IUGR) fetuses by means of biophysical profile (BPP) vis-à-vis Doppler velocimetry studies of the fetal um...

Background: Doppler ultrasonography enables the investigation of vascular blood flow indexes in gestational assessment, being able to detect resistances that can affect fetal and maternal circulation, such as cases placental insufficiency, associated with cerebral oxygenation deficit distress. The study aims assume hemodynamically normal values final third gestation bitches, umbilical, uteropla...

INTRODUCTION Ultrasonic fetal biometry and arterial Doppler flow velocimetry are widely used to assess the risk of pregnancy complications. There is an extensive literature on the relationship between pregnancy outcomes and the size and shape of the placenta. However, ultrasonic fetal biometry and arterial Doppler flow velocimetry have not previously been studied in relation to postnatal placen...

Intrauterine growth restriction (IUGR) represents a serious condition that can lead to increased perinatal morbidity, mortality and postnatal impaired neurodevelopment. There are two distinct phenotypes of IUGR: early onset and late onset IUGR with different onset, patterns of evolution and fetal Doppler profile. In early onset preeclampsia the main Doppler modifications are at the level of umb...

OBJECTIVE To assess the diagnostic power of the umbilical venous-arterial index (VAI) for the prediction of poor fetal outcome. SUBJECTS AND METHODS This was a retrospective, cross-sectional clinical study in which normalized umbilical vein blood volume flow rate (nUV) (mL/min/kg estimated body weight), umbilical artery pulsatility index (UAPI), the newly developed VAI (nUV/UAPI), and the ute...

Background: There have been researches on the evaluation of Doppler vascular impedance in hypertensive disorders complicating pregnancy (HDCP). With respect to the method of analysis used and the conclusions drawn in previous studies, different vessels were usually viewed separately and independently. This study was designed to evaluate Doppler vascular impedance changes in HDCP from a new pers...
