Middle cerebral artery to uterine artery pulsatility index ratios in pregnancy with fetal growth restriction regarding negative perinatal outcomes

چکیده
Background/Aim: Fetal growth restriction (FGR) causes a high risk of perinatal morbidity and mortality, the timing correct delivery time decision remains controversial. Cerebroplacental ratio (CPR), umbilical artery, uterine artery (UA) middle cerebral (MCA) Doppler studies are used to predict adverse outcomes in FGR. However, since there is insufficient reliability for each separately together, search new methods continues. This retrospective study was conducted determine degree neonatal fetuses suspected having FGR by evaluating MCA UA pulsatility index (PI) ratios together with frequently examinations. Methods: cohort single-center hospital approval Medical Institutional Ethics Committee. A total 424 pregnant women admitted tertiary diagnosed between July 2020 December 2021 who were informed approved included study. Gestational age confirmed first trimester sonographic measurements pregnancy. All examined USG mean UA, fetal MCA, ductus venosus, CPR (MCA/umbilical ratio) cerebrouterine (MCA/UA) PI values measured. Negative recorded as blood gas level newborn at 7.2 below, Apgar score 7 below fifth minute, needing intensive care (NICU). Adverse postnatal compared findings. If no signs negative outcome, it considered positive outcome. least one symptoms present, outcome Results: Decreased decreased significantly positively associated an increased likelihood exhibiting pregnancies (P < 0.001, P respectively). The receiver operating characteristic (ROC) curve analysis showed that optimal cut-off value 1.41 57.37% sensitivity 62.50% specificity (AUC: 0.629; 95% CI: 0.581–0.675). When taken 1.2069, 42.86% 83.93% predicting this 0.001). Conclusion: most successful criterion distinguishing outcomes. It has been demonstrated after can also be distinction. higher than artery. situation shows (alone or when evaluated PPV NPV ratios) added other examinations

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.

Background Fetal growth restriction is the second leading cause of perinatal morbidity and mortality. The incidence of intrauterine growth restriction (IUGR) is estimated to be approximately 5 percent in the general obstetric population. Abnormal uterine artery suggest a maternal cause for the growth restriction where as normal uterine artery Doppler studies suggest that a fetal cause. Use of u...
متن کاملUse of conditional centiles of middle cerebral artery pulsatility index and cerebroplacental ratio in the prediction of adverse perinatal outcomes.
INTRODUCTION Centiles of middle cerebral artery pulsatility index and cerebroplacental ratio are useful for predicting adverse perinatal outcomes. A 'conditional centile' is conditioned by a previous measurement reflecting degree of individual change over time. Here we test whether such centiles are independent predictors and whether their combination improves prediction. MATERIAL AND METHODS...
