Normal uterine artery blood flow

The value of uterine artery blood flow is also an important indicator for judging whether the uterus is healthy. The normal value of uterine artery blood flow is generally between 2.62-0.85. This is the range of uterine artery blood flow for women who are not pregnant. If you are already pregnant, the normal value of uterine artery blood flow will also change, between 2.08-0.43.

Uterine artery blood flow

Uterine artery blood flow in non-pregnant and early pregnant women presents a high-resistance waveform with a high peak in systole and a low diastolic phase, often accompanied by an early diastolic notch. At 14-18 weeks of pregnancy, the spiral arteries at the placental bed are eroded by trophoblastic cells, which reduces vascular resistance and causes the blood flow to gradually become low-resistance with abundant diastolic blood flow, and the S/D and RI values ​​decrease accordingly. Uterine artery blood flow can reflect the blood perfusion of the uterus. If the uterine artery blood flow is abnormal, it may lead to embryo arrest and repeated implantation failure. Uterine artery blood flow may also change when pregnant women suffer from diseases such as thrombophilia and uterine vascular malformations. Therefore, it is important to measure uterine artery blood flow in cases of recurrent implantation failure, fetal growth restriction, or pregnant women with thrombophilia. This can help detect some abnormalities early and allow for early intervention, which is beneficial for improving adverse pregnancy outcomes.

What is the normal value of uterine artery blood flow?

First of all, for normal women who are not pregnant, the normal value of uterine artery blood flow is 2.62 to 0.85. If a woman is already pregnant, then the normal value of uterine artery blood flow for women in this period will be relatively higher, between 2.08 and 0.43. If a pregnant woman's uterine artery blood flow is too high, it can easily cause the fetus in the pregnant woman's belly to suffer from hypoxia.

Secondly, if the test finds that the uterine artery blood flow is too high and the fetus is suffering from hypoxia, then at this time, the woman needs to lie down and rest, and at the same time pay attention to oxygen inhalation and supplementation, so that the fetus can slowly return to normal and not affect the growth and development of the fetus. Pregnant women should pay attention to the fetal movements and heart rate on a daily basis to detect abnormalities in time.

In addition, the reason why a woman's uterine artery blood flow is higher after pregnancy is that her belly gradually grows bigger. In order to better provide nutrition to the fetus, the blood vessels in the uterus will become thicker and the blood flow will become faster, which is good for the development of the fetus. Therefore, the uterine artery blood flow value of pregnant women will increase.
