Abstract
Anatomical structure of placenta greatly influences in function. Examination of placental anatomy has been useful in-utero as well as after parturition. A total number of 100 placentae with umbilical cords and their fetuses were studied. The maximum number of anomalies were between 31-40 cm of cord. Maximum mid-thickness of 1.0-2.0 cm followed by 2.1-2.5 cm in 2nd trimester with 4 anomalous fetuses. In third trimester the mid-thickness of cord was more with maximum cases lying between 2.1-3.5 cm 12 anomalies. Eccentric type (75%), Central (23%) and Battledore (2%) has 10, 6 and no anomalies respectively. Irregular placental shape has relatively more anomalies. Placental length has an even distribution of anomalies according to number of cases but they distributed mostly on shorter arm. Mid-thickness for umbilical cord seems to have more anomalies in 3^rd trimester group. True cord knots were associated with increased incidence of anomalies per cases. Weight of placenta does not affect distribution of anomalies in our study. Irregular placental shape was associated with higher incidence of anomalies as thin placenta in third trimester of pregnancy.
