Uterine arterial Doppler ultrasound in prediction for preeclampsia in 2nd trimester of pregnancy

Abstract

Background: Pre-eclampsia (PE) is a significant contributor to maternal and perinatal mortality and morbidity. The uterine arteries' blood flow velocity waveforms can be recorded non-invasively with a Doppler examination. This study set out to assess the importance of the uterine artery. The potential predictive value of Doppler screening for pre-eclampsia during the second trimester of pregnancy.Methods: This study involved the enrolment of 100 pregnant women during the second trimester. Among them, 50 had low-risk pregnancies while the other 50 had high-risk pregnancies. The procedure involved the utilization of a uterine artery Doppler ultrasound machine equipped with B-mode, pulsed Doppler, and colour flow imaging capabilities. Results: Doppler data were compared to pregnancy outcomes, such as hypertension or IUGR. The study assessed uterine artery parameters' sensitivity, specificity, PPV, NPV, and accuracy for preeclampsia prediction. Sensitivity, specificity, PPV, NPV, and accuracy were 91.7%, 95.3%, and 94%. Additionally, the study examined the bilateral notch and notch for preeclampsia, with respective values of 50%, 96.9%, 90%, 77.5%, and 80%. The risk factors associated with the highest rate of pulmonary embolism (PE) were history (80%), hypertension (75%), abortion (66.7%), renal disease (66.7%), and obesity (60%). Regarding the risk factors associated with the highest rate of intrauterine growth restriction (IUGR), the past medical history ranked first with a prevalence of 60%, followed by a history of abortion and hypertension, both with a prevalence of 50%.Conclusions: Women who exhibit abnormal uterine arteries Doppler examination results are at a heightened risk of experiencing subsequent complications, especially those that necessitate premature delivery. The University of Texas at Austin the Doppler technique is an advantageous and promising non-invasive method for detecting obstetric outcomes.
