This information can tell you whether you have identical or fraternal twins. And the information also helps your health professionals recommend the right pregnancy care for you. If you have any complications, specialist checks can pick them up early, which means they can be treated early. Obstetricians are skilled and experienced in providing antenatal care for twin pregnancies. Also, health professionals will usually recommend that you give birth in a hospital, rather than in a birth centre or at home. Hospitals have the facilities needed to manage any complications of a twin pregnancy, like premature birth. You might have more frequent ultrasounds than this.

Most of the time scans are there to simply help confirm your little one is developing healthily – with the added bonus that you get to see your baby moving around. But sometimes they can reveal a few more serious issues. In the UK you will be offered at least two, the first at 8 to 14 weeks and the second at 18 to 21 weeks.

A gel is applied to your tummy – it may feel a little cool – and then a small hand-held device is moved over your skin, which sends an image of your little one to a screen. You may be asked to have a full bladder for some of your scans – this helps to create a clearer picture of your baby. Your baby will be teeny at this stage, so in order to get as clear a picture as possible, the scan may be carried out using a small probe that goes inside your vagina.

As the frequency of multiple pregnancies is increasing, every obstetrician has to know that the correct, accurate, and timely determination of gestational age, chorionicity, and amnionicity has significant importance in the management of a multiple pregnancy. Surveillance, complications, outcome, morbidity, and mortality are totally different in a monochorionic and a dichorionic pregnancy. In this chapter, we will present the sonographic figures that are visualized in the first trimester in a multiple pregnancy and help us define the gestational age, chorionicity, and amnionicity.
We will classify them into two periods: the early first trimester, including the 10 first weeks of gestation and the late first trimester including the period between the 10th and 14th week of gestation. Finally, we will review some interesting, although infrequent, cases from the literature, showing that pitfalls in the determination of both chorionicity and amnionicity exist and highlighting the importance of being aware of their subsistence.
Multiple Pregnancy – New Challenges. It is a well-established fact that multiple pregnancies occur more commonly nowadays than a few decades ago. The progress of reproductive technologies and in vitro fertilization has played a major role in this increase. As we speak about history, the vast majority of multiple pregnancies that occurred in the past were diagnosed during the intrapartum period [ 2 ].
Today, as the use of ultrasound has become a routine in daily medical practice, multiple pregnancies are diagnosed in the initial ultrasound scan [ 3 ]. Beyond the diagnosis of early multiple pregnancy, ultrasound scan is more than necessary to define chorionicity, amnionicity, and gestational age [ 4 ]. In this chapter, we will present the ultrasound figures that help us determine gestational age, chorionicity, and amnionicity, focused on the 14 first weeks of gestation in multiple pregnancies.
Nonetheless, we will review some cases from the literature that show that situations can be a little more complicated and may lead to a false diagnosis of chorionicity and amnionicity, in order to highlight that when we manage multiple pregnancies, we have to be alert about exceptions despite being infrequent [ 5 ]. A twin pregnancy can be either dizygotic two-third of twin pregnancies , in which two different eggs are fertilized by two different sperms, and in this case, the pregnancy is always dichorionic-diamniotic or monozygotic.
Assessment of chorionicity and amnionicity see below is vital first-trimester assessment is optimal. Twins frequently change position: the description of fetal position must be clear, and state if the previously leading twin is no longer presenting; however, the labelling of twins A and B must not be changed during the pregnancy. Discordant CRL in monochorionic twins is associated with an increased risk of subsequent development of selective fetal growth restriction sFGR.
