Uterine Artery Doppler (UAD) is a very specialized ultrasound of the maternal uterus. It requires mapping out the uterine arteries on both sides of the uterus and then obtaining doppler measurements. Those measurements are interpreted and help in determining a patient’s risk of developing preeclampsia during the current pregnancy.

Significance. The presence of notching in late pregnancy is an indicator of increased uterine vascular resistance and impaired uterine circulation 2. Bilateral notching is more concerning. Uterine artery (UtA) Doppler ultrasound examination has become a valuable method for indirectly assessing uteroplacental circulation from early gestation 1 and has been considered as a potential screening tool for the development of pre‐eclampsia, fetal growth restriction, placental abruption and stillbirth 2-11.

A uterine artery Doppler ultrasound measurement is used to check the blood flow between you and your baby. It can be carried out during an ultrasound scan. The Doppler measurement uses sound waves to check if the Plasencia W, Maiz N, Poon L, et al. Uterine artery Doppler at 11 + 0 to 13 + 6 weeks and 21 + 0 to 24 + 6 weeks in the prediction of pre-eclampsia.

uterine artery Doppler is predictive of FGR in the second trimester,and abnormal values in a high-risk population will increasethe development of FGR later AboutPressCopyrightContact Changes in the uterine artery blood flow waveform during pregnancy have been the subject of several studies and are frequently attributed to trophoblastic invasion of the myometrium. We report on a case of a third-trimester abdominal pregnancy in which we performed Doppler velocimetry of the uterine arteries and observed low-resistance flow and absence of notching bilaterally.

While notching can be either systolic or diastolic, it is typically seen as a trough-like notch between the systolic and diastolic phases.

Effective screening for pre-eclampsia can be achieved by measurement of the uterine artery pulsatility index (PI) at 11–13 weeks' gestation, used in combination with maternal history, blood pressure, serum pregnancy-associated plasma protein-A and uterine artery Doppler is predictive of FGR in the second trimester,and abnormal values in a high-risk population will increasethe development of FGR later AboutPressCopyrightContact Hi there, I had a previous stillbirth so I was given a uterine artery doppler scan at 24 weeks in this pregnancy. I got results which are well below average (which is good) of 0.46 for the left artery and 0.7 for the right. All my scans have shown baby growing well. I am now 28 weeks. Recently I have been having a lot less movement and yesterday at my scan the sonographer checked the uterine In this instructional video Dr Liona Poon is guiding you in the measurement of uterine artery Doppler PI as part of the first trimester combined pre-eclampsi Uterine artery Doppler • Normally carried out at 20 -24 weeks gestation –The uterine artery is sampled to examine the spectral Doppler waveform. • Both arteries are examined and reported on. • In addition the position of the placenta should be recorded, especially if it is § The uterine artery is typically seen crossing the EIA anteriorly § Select a portion of the uterine artery which courses at a favourable Doppler angle 0-60 degrees § Optimise the spectral Doppler baseline and PRF to get a large waveform Uterine Artery Doppler Pedroso et al.

A recent meta-analysis by Velauthar et al. [ ]reviewed the accuracy of uterine artery Doppler analysis in the r st trimester in the prediction of FGR and preeclampsia. Eighteen studies Colour Doppler imaging was applied afterwards to identify the uterine artery as it crosses the external iliac artery. The wall filter was set at 50–60 Hz and the angle of insonation was below 20°. Pulsed wave Doppler with a gate size of 2 mm was placed over it at about 1 cm below the crossover point [36] of the uterine artery and the external iliac artery to generate the spectral wave pattern. § The uterine artery is typically seen crossing the EIA anteriorly § Select a portion of the uterine artery which courses at a favourable Doppler angle 0-60 degrees § Optimise the spectral Doppler baseline and PRF to get a large waveform Uterine artery Doppler examination is an e ective non-invasive screening test for the development of PE in pregnancies at risk, particularly appropriate in health systems with limited means of evaluating other biomarkers.

The uterine artery doppler is a scan of the blood going TO the placenta. The umbilical artery doppler is a scan of the blood IN the umbilical cord. Very different thing. Readings of PI 1.20 for the uterine artery would be very worrying indeed. However, for the umbilical artery this reading is only slightly higher than average (about the 60th
