Multiple Pregnancy

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.

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.

Can a Hidden Twin Be Detected by Ultrasound Imaging?
