The uterine decidua and decidual arteries must be
invaded by trophoblasts in order for the plcenta to
develop. Preeclampsia (PE), foetal growth restriction
(FGR), and small-for gestationalage (SGA) infants are all
caused by abnormalities of the placenta. Uterine artery
Doppler allows for the prediction of important vascular
events during pregnancy (UAD). Finding alterations in
uterine and placental blood vessels can be a helpful
diagnostic tool for pregnancy issues from the
implantation stage through the end of the pregnancy. The
purpose of thisreview is to assemble research on the
functions of Uterine artery PI in pregnancy problems.
From January 1, 1983, until October 30, 2021, we take
into account all pertinent English-language articles. The
ability to foresee pregnancy issues in advance enables
medical professionals to implement prompt measures to
prevent or decrease harm to mothers and newborns.
Before 16 weeks of pregnancy, using low-dose aspirin
every day can greatly lower the likelihood of pregnancy
problems. UAD can be combined with other maternal
variables, biochemical indicators, and foetal
measurement data to identify high-risk populations from
the beginning through the end of pregnancy. Determining
high-risk populations can help reduce maternal mortality.
Additionally, strict monitoring for high-risk pregnant
women can be conducted by moderate risk stratification,
reducing the frequency of adverse events.
Prospective study was conducted in 110 patient with
raised uterine PI out of 631 came for routine antenatal
visit from January 2021 to November 2022 in SKNMC &
In our study of 110 patients, we observed that
pateints with raised Uterine artery PI showed low birth
weight which was decreased as compared to normal
neonate after birth.
We conclude that uterine artery pulsatility
index (PI) with additional biochemical markers in mid
trimester helps the practioner in prediction for earlyonset fetal growth restriction. Monitoring uterine artery
PI in mid-trimester in high-risk pregnancies can also aid
in determining the method of delivery and reduces risks.
