ABSTRACT Introduction: Abnormalities in the insertion of umbilical cord is associated with a number of complications in pregnancy and these complications may adversely affect the fetus. The aim of this study was to evaluate the variations in the attachment of umbilical cord in normal and pre-eclamptic pregnancies and to assess the effects of variable cord insertions on fetal birth weight. Materials and Methods: Seventy placentae each of normotensive and pre-eclamptic pregnancies were studied (n=140). After delivery, weight of the baby was recorded by using weighing machine and the attachment of umbilical cord on placenta was observed. Results: In the present study, commonest site of insertion of umbilical cord was central (60%) in normal pregnancies, whereas in pre-eclamptic pregnancies, a common site of insertions of umbilical cord were central (37.14%) and/or eccentric (34.28%). Marginal cord insertions were found 2.11 times more in pre-eclamptic pregnancies as compared to normal pregnancies.
