Linear Correlation of Uterine Artery Pulsatility Index (PI) in Mid Trimester in Pregnant Female with Foetal Birth Weight

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. Methods 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 & GH, Pune. Observation 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. Conclusion 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
