PURPOSE To evaluate the merit of umbilical artery Doppler study as a predictive marker of perinatal outcome in preterm small for gestational age (SGA) infants. MATERIALS AND METHODS A total of 218 patients at 27 - 36 weeks of gestational age (GA) who received antenatal umbilical artery Doppler velocimetry and delivered singleton infants with SGA. The ratio of peak-systolic to end-diastolic bl...

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...

A new laser velocimetry technique, Doppler global velocimetry, is described. This technique is capable of simultaneously measuring in real time the three components of velocity of an entire particle field i l luminated by a laser l ight sheet . A prototype one-component velocimeter is described along with the signal processing electronics. The system was tested by measuring the velocity field f...

BACKGROUND The aim of the study was to evaluate the relation between maternal placental Doppler velocimetry, levels of the maternal glucose, and clinical signs of vasculopathy in pregnancy complicated by pregestational diabetes mellitus. METHODS AND RESULTS A retrospective study of 155 pregestational diabetic women between the 22nd and 40th weeks of pregnancy, categorized in White classificat...

The work presented here describes a method that allows three component velocity measurements to be made, quickly and non-intrusively, across a plane in a flow defined by a laser light sheet. The method, two frequency planar Doppler Velocimetry (2ν-PDV) is a modification of the Planar Doppler Velocimetry (PDV) technique, using only a single CCD camera, and sequential illumination of the flow usi...

In order to improve perinatal outcomes and reduce mother foetal morbidity mortality especially in high-risk pregnancies, there is an immense need do thorough antepartum surveillance test. Aims Objectives: To compare modified biophysical profile (MBPP) Doppler studies results for prediction of outcome evaluate the association between mode delivery abnormal MBPP.Methodology: This a prospective ob...

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 ...
