Dopplerometry in pregnancy is a procedure that will allow a gynecologist to learn about the condition of a woman and a baby. Let's consider all the nuances of this procedure: when to do dopplerometry and how it is conducted, where it can be done and how much it costs. So, about everything in order.
Dopplerometry gives the gynecologist, who watches the course of pregnancy, more information about the state of mother and child. So, Doppler will tell about the blood supply of the placenta and uterus, as well as whether there are threats of gestosis, that is, late toxicosis. How is the placenta located, are there any violations in it that can provoke its premature detachment. Dopplerometry during pregnancy will tell you about the condition of the baby, about the vessels in the umbilical cord and about whether signs of heart disease or blood supply disorders.
The basis of Doppler is the Doppler effect, that is, the process of changing the sound frequencies, which are reflected from the moving object (in this case, the cellular elements of the blood). Dopplerometry during pregnancy can be carried out at any time. The procedure is very simple, but informative, and also safe for both the baby and the mother.
Dopplerometry should be performed only by a qualified doctor who will be able to decipher the indications. As for decoding, it is carried out on modern modules of ultrasound devices. Often dopplerometry is carried out together with a standard ultrasound examination.
Ultrasound in pregnancy with dopplerometry
Uzi during pregnancy with dopplerometry are performed for all women, since such a study allows for more detailed study of the status of a woman and traces the course of pregnancy. The results, which will be obtained from ultrasound with dopplerometry, will help to observe the pregnancy in more detail, control it and protect it from violations and complications. It is absolutely safe, both for the mother and the child. Uzi with dopplerometry give an opportunity to learn about:
- The course of the course of pregnancy, from the first months to the delivery.
- The location of the umbilical cord of the fetus and the threat of umbilical cord entanglement.
- Blood supply to the uterus.
- The state of the placenta.
The results of the study are a table with abbreviations, which we will consider below.
How is dopplerometry done during pregnancy?
How doppler is performed during pregnancy, the gynecologist decides, it is he who sets the time for the study. The first procedure is performed at 9-13 weeks of pregnancy. The study allows you to accurately determine the duration of pregnancy and, if necessary, find out how the first months of bearing of the baby occur. The advantage of dopplerometry in the first trimester of pregnancy is that the results of the analysis will be able to determine the threat of miscarriage.
The second procedure is performed on the 15-25th week of pregnancy. The main goal of the study in this period is to find out how the baby is developing, its size, the correct location and development of the organs and in what condition the placenta. The third mandatory dopplerometry in pregnancy is performed at 30-36 weeks of gestation. The purpose of the study is to find out whether everything is in order with the baby and how much the female organism is ready for the forthcoming birth. If pregnancy passes with complications, the gynecologist may prescribe additional dopplerometry sessions.
Dopplerometry in pregnancy is a great opportunity to learn more about pregnancy and its course. For a woman and her future child it is an opportunity to know in time about the complications and pathologies that can threaten both the health of the mother and the baby. And this is an excellent chance to cure in time and take measures for the normal development and birth of the baby.
Norms of dopplerometry in pregnancy
The norms of dopplerometry in pregnancy is an indicator that the bearing of the baby passes without violations and deviations. But do not worry if the Doppler scan showed abnormalities. Deviations will allow the gynecologist to correct the course of pregnancy and warn the woman against possible complications. Such research as dopplerometry allows to detect prevent pathologies and deterioration of the development of the baby. If the results of the procedure showed that everything is normal, then this indicates that the pregnancy is proceeding well, the baby receives all the necessary nutrients.
The norms of dopplerometry in pregnancy show the child's developmental process. By deviations from the norm, a doctor can correct the course of pregnancy, treat a woman, prescribe medications and make a decision about how the delivery will take place, so that the baby is healthy.

Deciphering of dopplerometry in pregnancy
Deciphering dopplerometry in pregnancy is the work of a professional gynecologist who is familiar with this procedure. In order that future mothers can independently learn about how the Doppler has passed and what the results mean, we suggest decoding values:
AO - aorta; AV - aortic valve; PV - pulmonary vein; RA - pulmonary artery; PV - valve of the pulmonary artery; LA - left atrium; LV - left ventricle; MV - mitral valve IAS - interdigitinal septum; IVS - interventricular septum; IVS - inferior vena cava; RV - right ventricle; TV - tricuspid valve HV - hepatic vein; AA - aortic arch; abdominal aorta; AW - anterior wall of the left ventricle; DAO - descending thoracic aorta; LCA - left coronary artery; RA - right atrium; ATL - the front leaf of the tricuspid valve; aAO - ascending aorta; CS - coronary sinus; LCC - left coronary valve; AML - the front valve of the mitral valve; LSA - left subclavian artery; LCA - left carotid artery; LVOT - the outflow tract of the left ventricle; LPA - left branch of the pulmonary artery; PF - pericardial fluid; NCC - non-coronary valve aortic valve PML - posterior valve mitral valve; RM - papillary muscle; RCA - right coronary artery; PW - posterior wall of the left ventricle; RPA - right branch of the pulmonary artery; RCC - right coronary valve of the aortic valve; RVOT - the outflow tract of the right ventricle; RSPV - right upper pulmonary vein; SVC - the superior hollow vein. RVW is the wall of the right ventricle;
All of the above values may vary, depending on the drugs that are being used. Therefore, it is only the gynecologist who can accurately find out the results and decode them.

Parameters of dopplerometry in pregnancy
The parameters of dopplerometry in pregnancy allow you to know about the course of pregnancy. Having received the results of dopplerometry, knowing the decoding of the indicators and their rate, the gynecologist has a prognosis for the outcome of pregnancy and, if necessary, takes measures for the most favorable outcome.
We suggest that you consider the norm of dopplerometry in pregnancy.

Future moms should know that the norm of dopplerometry is an indicator of the normal development of the baby. Most often deviations from the norm and complications appear in late pregnancy. Therefore, it is necessary to conduct regular Doppler and ultrasound examinations, which will help you to know about the state of the fetal blood circulation. At threat of the gynecologist can send the pregnant woman on treatment in a hospital. How do dopplerometry in pregnancy?
Dopplerometry in its specific features resembles the procedure of ultrasound, the difference is only in the technology of the apparatus and the results of the study. How do dopplerometry in pregnancy - the future mother is settled on the couch, a special gel-conductor is applied to the tummy. After that, the doctor gynecologist holds the apparatus and displays the result of the examination on the screen.
Note that Doppler research is completely safe for both mother and baby. Therefore, women who are only going to this procedure should not worry.
Price of dopplerometry in pregnancy
The price of dopplerometry in pregnancy depends on the type of study. The average cost of the procedure is from 60 to 200 hryvnia. The cost directly depends on the clinic, which will conduct the study, the qualification of the doctor and the period of pregnancy.
In the first trimester of pregnancy and in recent weeks, the procedure requires special care and professionalism of the doctor, who deciphers the results. Therefore, during this period of pregnancy the price of Doppler is slightly overestimated.
Where to make dopplerometry in pregnancy?
If you are looking for where to make dopplerometry in pregnancy, then it's worth discussing this issue with your gynecologist who is watching your pregnancy. As a rule, ultrasound is performed in specialized medical centers. In such institutions, professional qualified specialists work, using only modern equipment for doppler or ultrasound examination of pregnant women.
