The study was conducted at the Department of ANATOMY in collaboration with the Department of Obstetrics and Gynaecology in Gauhati medical collge and hospital, Guwahati from june 2009 to may 2012. Placentae expelled during normal vaginal delivery were included in the study. The study group comprised 103 placentae from pregnant women of 30 to 40 completed weeks, who had a blood pressure at or above 140/90 mmHg on at least two occasions 6 hours apart after 20 weeks of gestation, with or without oedema and/or proteinuria. The results were compared with those of 34 placentae of normotensive mothers those women between 18 to 35 years of age with a gestational age of the fetus between 37 to 42 weeks were examined. Both primigravida and multigravida of average height and weight upto 4th parity who were free from othersystemic illness were taken in the study. Morphological findings in both groups studied (normotensive and hypertensive mothers). The weight of placenta, thickness as well as diameter is found to be diminished in pregnancy induced hypertension. PIH significantly affects the placenta by reducing its weight and dimensions. These changes may cause placental insufficiency as a result of compromised utero-placental blood flow, thus producing an adverse affect on the neonatal birth weight. PIH has definite influence on morphology of placenta and therefore affects the growth of the fetus.
