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 0034: Myometrial contraction (arrow) causes underestimation of the amniotic fluid volume

Mentions: The most common reason for error is excess transducer pressure.[57] Such pressure causes underestimation of the volume. Other factors include maternal obesity and floating particles in the fluid, which interfere with the visualization of the pocket. Estimation based on the measurement of a single pocket also has its limitations and it is not always necessary that the tallest pocket will be the correct one; for instance, its width may be less. Uterine contraction also tends to cause underestimation of the quantity of amniotic fluid [Figure 34].
