“…In our study, the mean values of umbilical artery Doppler indices (S/D, PI) are similar to the study reported by Chanprapaph et al 19 and Owen et al 21 The values of mean PI are similar to those reported by Acharya et al 22 in Norway and Ferdous et al 23 in Bangladesh. The values of mean S/D are similar to those reported by Kofinas et al 24 in North Carolina, Harneet et al, 25 and Singh 26 in India.…”

Aim: This study was designed to evaluate umbilical artery Doppler indices [systolic/diastolic (S/D) ratio and pulsatility index (PI)] in normal fetus at term. Doppler ultrasound of umbilical arteries is widely accepted as a primary tool for quantitative analysis of fetoplacental and uteroplacental blood flow in highrisk pregnancies.Materials and methods: A total of 100 normal singleton pregnant women were recruited in this study from the Radiology Department Fatima Memorial Hospital (FMH) from August 3, 2012 to November 30, 2012. Their gestational ages were from 37 to 40 weeks.Results: A total of 100 Doppler indices measurements were performed. The values of S/D ratio were less than 3 and the values of mean PI were less than 1 from 37 to 40 weeks of gestation. Conclusion:Umbilical artery Doppler indices among normal pregnant women in our population are similar to most published reference values from other parts of the world.Clinical significance: This normative data will serve as a basis for the evaluation of the umbilical artery circulation in our population.

“…The highest prevalence was reported by Yoon et al, who reported a prevalence of AEDF or REDF of 2.13% amongst 328 unselected-risk women in South Korea [38]. The four studies (898 women) conducted in lower middle-income countries (Bangladesh, Papua New Guinea, Nigeria and Tunisia) did not report any cases of AEDF or REDF [39][40][41][42]. Similarly, a three-country prospective cohort study of 431 healthy, low-risk women by Drukker et al in Brazil, Kenya and the UK identified no AEDF cases in any country [29].…”

Prevalence of abnormal umbilical arterial flow on Doppler ultrasound in low-risk and unselected pregnant women: a systematic review

et al. 2021

Background While Doppler ultrasound screening is beneficial for women with high-risk pregnancies, there is insufficient evidence on its benefits and harms in low- and unselected-risk pregnancies. This may be related to fewer events of abnormal Doppler flow, however the prevalence of absent or reversed end diastolic flow (AEDF or REDF) in such women is unknown. In this systematic review, we aimed to synthesise available data on the prevalence of AEDF or REDF. Methods We searched PubMed, Embase, CINAHL, CENTRAL and Global Index Medicus with no date, setting or language restrictions. All randomized or non-randomized studies reporting AEDF or REDF prevalence based on Doppler assessment of umbilical arterial flow > 20 weeks’ gestation were eligible. Two authors assessed eligibility and extracted data on primary (AEDF and REDF) and secondary (fetal, perinatal, and neonatal mortality, caesarean section) outcomes, with results presented descriptively. Results A total of 42 studies (18,282 women) were included. Thirty-six studies reported zero AEDF or REDF cases. However, 55 AEDF or REDF cases were identified from just six studies (prevalence 0.08% to 2.13%). Four of these studies were in unselected-risk women and five were conducted in high-income countries. There was limited evidence from low- and middle-income countries. Conclusions Evidence from largely observational studies in higher-income countries suggests that AEDF and REDF are rare among low- and unselected-risk pregnant women. There are insufficient data from lower-income countries and further research is required.

“…Studies excluded from this review and the reasons for exclusion are listed in Table S1. A total of 38 studies from 22 countries met the inclusion criteria and were included in the final analysis. The main characteristics, the overall study design and statistical and reporting methods quality scores for each included study are presented in Table S3.…”

There is considerable methodological heterogeneity in studies reporting reference ranges for Doppler indices of UA, MCA and CPR, and the resulting references have important implications for clinical practice. There is a need for the standardization of methodologies for Doppler velocimetry and for the development of reference standards, which can be correctly interpreted and applied in clinical practice. We propose a set of recommendations for this purpose. This article is protected by copyright. All rights reserved.
