Placenta and umbilical cord, no doubt is a matter of interest and curiosity for ages for many anatomists, embryologists and obstetricians because of its incomparable importance in the intrauterine development of human being. Placenta and umbilical cord acts as a mirror which reflects intrauterine status of fetus. It is the most accurate record of infant’s prenatal experiences, so study of placenta and umbilical cord gives valuable clues in cases of adverse fetal outcome.

                We compared the lengths and diameters of umbilical cords of uncomplicated pregnancies with those of pregnancies complicated by hypertension. The effect of parity on the length and diameter of umbilical cords is also noted.

                We found that there is significant increase in length of umbilical cord and reduction in diameter of umbilical cord in hypertensive pregnancies than in uncomplicated pregnancies. In both the groups, as the parity increase the length and diameter of umbilical cord also increases.

                Alterations in various parameters may be attributed to the effect of ischaemia produced by hypertension on the umbilical cord, subsequently affecting the foetus in the womb of mother. Appropriate precautions if instituted during pregnancy, complications of PIH can be reduced.
