Bottom Line: These three main components decide whether there will be an uneventful pregnancy and the successful birth of a healthy baby.Population and race also influence pregnancy outcomes to some extent in certain situations.USG is the most sensitive imaging tool currently available for evaluation of these factors and can offer considerable information in this area.

ABSTRACT
The intrauterine environment has a strong influence on pregnancy outcome. The placenta and the umbilical cord together form the main supply line of the fetus. Amniotic fluid also serves important functions. These three main components decide whether there will be an uneventful pregnancy and the successful birth of a healthy baby. An insult to the intrauterine environment has an impact on the programming of the fetus, which can become evident in later life, mainly in the form of cardiovascular diseases, diabetes, and certain learning disabilities. The past two decades have witnessed major contributions from researchers in this field, who have included ultrasonologists, epidemiologists, neonatologists, and pediatricians. Besides being responsible for these delayed postnatal effects, abnormalities of the placenta, umbilical cord, and amniotic fluid also have associations with structural and chromosomal disorders. Population and race also influence pregnancy outcomes to some extent in certain situations. USG is the most sensitive imaging tool currently available for evaluation of these factors and can offer considerable information in this area. This article aims at reviewing the USG-related developments in this area and the anatomy, physiology, and various pathologies of the placenta, umbilical cord, and the amniotic fluid.

Figure 0002: Placenta. Reliable confirmation of location is seen at 11 weeks; in this case an anterior placenta (arrow)

Mentions: The implantation site of the placenta can be identified on sonography as a hyperechoic focus in the early period of gestation [Figure 1]. The site of implantation is known to have an association with perinatal outcome. Lateral placentation is seen in fetuses with intrauterine growth restriction (IUGR).[2] Implantation occurs at around 8–10 weeks, when the placenta is formed by the interaction of the deciduas basalis of the endometrium and the chorionic villi of the fetus. True definition of the placenta is possible only 10–11 weeks after conception [Figure 2].
