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.

Grey-scale (A) and color Doppler (B) images of the cord suggest the presence a thick cord (arrow). The fetus had megacystis. Follow-up after a week revealed a cystic hygroma around the fetal skull; IUD occurred 1 week later

Figure 0023: Grey-scale (A) and color Doppler (B) images of the cord suggest the presence a thick cord (arrow). The fetus had megacystis. Follow-up after a week revealed a cystic hygroma around the fetal skull; IUD occurred 1 week later

Mentions: Literature describes an association between a thick umbilical cord between 10 and 14 weeks of gestation and aneuploidy [Figure 23]. A thickness of more than the 95th percentile is significantly associated with aneuploidy. The thickening can persist into the second trimester. An association with an abnormal nuchal thickness (NT) and abnormal serum biochemical markers is known. It is also suggested that, like NT, the increased umbilical cord thickness can regress in the later stages of gestation.[39]
