Multiple pregnancy
Twins are two fetuses which develop simultaneously in the uterus. The incidence of twin pregnancy has increased over the years as a result of the widespread use of assisted reproduction.
A twin pregnancy is considered as high-risk. This type of pregnancy can develop some specific and potentially dangerous complications which cannot be observed in singletons.
The risk of occurrence of those complications is directly related to the number of future placentas (chorionicity) and the number of amniotic sacs (amnionicity).
A twin pregnancy with a single placenta (monochorionic) is associated with a higher risk than a twin pregnancy with two separate placentas (dichorionic). Therefore, ultrasound assessment of the number of placentas in twin pregnancies is an important prognostic factor for the final perinatal outcome.
Тhe ultrasound assessment of chorionicity (number of future placentas) in twins should be performed before 11 w.g. and at latest during the fetal anatomy survey at 11-13+6 w.g. The subsequent follow-up, likelihood of complications, prognosis and final perinatal outcome in monochorionic (with one placenta) and dichorionic (with two placentas) twins differ significantly.
The fetal anatomy survey in twins can be performed in the first, second and third trimester.
The principles of the scan are identical to those in a singleton pregnancy.
Repeated follow up scans are often performed in order to assess more precisely the fetal growth, amniotic fluid, blood flow, cervical length, etc.
The time interval between consultations is largely dependent on the correct and timely ultrasound assessment of chorionicity and amnionicity.
The fetal anatomy survey in twins is mainly performed by 2D ultrasound. In the course of the examination and under certain conditions, some 3D pictures or 4D videos may be taken. However, this is not the main objective of the scan.
We offer to all our patients at MC MARKOVS the full range of specialized ultrasound examinations in twin pregnancies, concerning the sonographic assessment of chorionicity and amnionicity, the fetal anatomy survey in the first, second and third trimester, as well as the additional follow-up scans. All examinations are carried out in a comfortable environment with high-quality ultrasound equipment by highly qualified specialists.
For more information about the possibilities of monitoring your twin pregnancy at MC MARKOVS, you can contact your doctor or call at the registration desk.
