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 0019: A tranverse section of the cord (arrow) shows a four-vessel cord

Mentions: Variations in the number of cord vessels are known, the commonest variant form being a single umbilical artery. The presence of any variation warrants a careful search for other anomalies. Four-vessel and five-vessel cords have been described [Figure 19] and the incidence of anomalies in these pregnancies is higher. Fused umbilical arteries are known. Hypoechoic and hyperechoic cords are also known to be associated with a poor pregnancy outcome.[32]
