Fetal middle cerebral artery and umbilical artery pulsatility index: effects of maternal characteristics and medical history.
OBJECTIVE To define the contribution of maternal variables which influence the measured fetal middle cerebral artery (MCA) and umbilical artery (UA) pulsatility index (PI) in the assessment of fetal wellbeing. METHODS Maternal characteristics and medical history were recorded and fetal MCA-PI and UA-PI (n = 36,818) were measured in women with singleton pregnancies attending a routine hospital...
متن کاملReproducibility of measurement of pulsatility index by Doppler ultrasound of the anterior cerebral artery of preterm infants.
Ten preterm infants were each studied by three observers using a commercial duplex Doppler ultrasound scanner, in order to determine the intra-observer and inter-observer variability in the measurement of pulsatility index (PI) of the anterior cerebral artery. There was considerable difference in estimates of PI, with a mean range of 0.11 between the three observers for each infant. Intra-obser...
متن کاملNormal value of pulsatility index of umbilical artery in second and third trimester of pregnancy.
This cross sectional study was carried out on 60 pregnant Bangladeshi women in the department of Radiology and Imaging, BIRDEM for measurement of Pulsatility Index (PI) of umbilical artery of their fetuses by duplex colour Doppler sonography during 2nd and 3rd trimester of pregnancies. Considering total 2nd and 3rd trimesters the mean PI value of umbilical artery was 1.24 (SD +/- 0.27). While c...
متن کاملPredictive Value of Middle Cerebral Artery to Uterine Artery Pulsatility Index Ratio in Hypertensive Disorders of Pregnancy
Aims and Objectives. (i) To determine the predictive value of cerebrouterine (CU) ratio (middle cerebral artery to uterine artery pulsatility index, MCA/UT PI) in assessing perinatal outcome among hypertensive disorders of pregnancy. (ii) To compare between CU ratio and CP ratio (MCA/Umbilical artery PI) as a predictor of adverse perinatal outcome. Methods. A prospective observational study was...
متن کاملHomocysteine and pulsatility index of cerebral arteries.
BACKGROUND AND PURPOSE A pulsatility index (PI) represents vascular resistance distal to an examined artery. The purpose of the present study was to evaluate an association between plasma total homocysteine (tHcy) and PIs of the cerebral arteries in patients with ischemic stroke. METHODS Consecutive patients with ischemic stroke referred to a neurovascular ultrasound laboratory were evaluated...
