Fetal and umbilical Doppler ultrasound in high-risk pregnancies

Abstract

Background-Abnormal blood flow patterns in fetal circulation detected by Doppler ultrasound may indicate poor fetal prognosis. It is also possible false positive Doppler ultrasound findings could encourage inappropriate early delivery.

Prognostic accuracy of antenatal doppler ultrasound measures in predicting adverse perinatal outcomes for pregnancies complicated by diabetes: a systematic review

“… 36 Nonetheless, another review reported that CPR was significantly better than UA and MCA Doppler in predicting composite adverse outcomes. 22 Contrary to our study, the review reported that CPR performed better than UA in predicting emergency delivery for fetal distress ( P =.003), but was comparable to UA Doppler in predicting perinatal death ( P =.686), low APGAR score ( P =.595), and NICU admission ( P =.107). In this study, MCA was significantly worse than UA and CPR in predicting emergency delivery for fetal distress ( P =.034; P =.013) and low APGAR score ( P =.017), and significantly worse than CPR in predicting composite adverse outcome ( P <.001).…”

Non-stress test as a predictor for high-risk pregnancy in the third trimester using fetal color Doppler

“…Our results showed that cases of abnormal Doppler and NST results had a significant increase in the rates of cesarean section (87% in Group D). Abnormal fetal assessments also played an important role in neonatal outcomes such as NICU admissions this finding aline with the study done by Ayyuub et al [ 10 ] The majority of neonates with variations in NST and Doppler values (66.7%) were admitted to NICU and this percentage corresponds to the results obtained by Alfirevic et al who discovered that an abnormality in Doppler measurements is associated with a significant relationship with increased NICU admission and neonatal mortality in the instance of growth restriction [ 1 ]. Additionally, the occurrence of meconium-stained liquor was higher among the groups of neonates with non-reactive NST, as it indicates fetal distress and hypoxemia that are associated with increased [ 11 ].…”

Intrauterine fetal deaths related to antiphospholipid syndrome: a descriptive study of 65 women

“…Our sample is too small to reach any conclusions about the Doppler findings in IUFD associated with APS. We agree with current recommendations that uterine and umbilical artery Doppler scans should be performed in high-risk patients, including those with a history of thrombosis, obstetric hypertensive disorder, or fetal loss [ 19 , 20 ].…”
