This review included 11 trials involving 37, pregnant women, comparing routine versus selective ultrasound before 24 weeks of gestation. Trials were conducted between and in high-income countries. Overall, trials were large, well-designed. GRADE quality of the evidence was considered to be moderate to low due to the lack of blinding, imprecision of results and presence of heterogeneity. The increased detection rates of multiple gestations, of fetal abnormalities at the time legal interruption of pregnancy is possible, and improved gestational dating with less induction of labour, have not resulted in improved outcomes for babies. The lack of data on economic impact is important, particularly in low-resource settings. No data on chorionicity, on diagnosis or management of ectopic pregnancy or abortion.

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.

Maternity – Antenatal
A dating scan is an ultrasound examination which is performed in order to establish the gestational age of the pregnancy. Most dating scans are done with a trans-abdominal transducer and a fullish bladder. If the pregnancy is very early the gestation sac and fetus will not be big enough to see, so the transvaginal approach will give better pictures. Dating scans are usually recommended if there is doubt about the validity of the last menstrual period.
By 6 to 7 weeks gestation the fetus is clearly seen on trans-vaginal ultrasound and the heart beat can be seen at this early stage 90 to beats per minute under 6 to 7 weeks, then to beats per minute as the baby matures.
