Study Of Arterial Pattern Of Normal Placenta By Corrosion Cast Method And To Correlate It With Its Surface Area

The aim of our study is to find out the arterial pattern of normal placenta by corrosion cast method and to correlate arterial pattern with the surface area. Two types of arterial patterns were found – Dispersed and Magestrial. 20 normal placenta were collected from labour room. 70% placenta were of dispersed variety and 30% were of magestrial variety. Maximum and minimum surface area in dispersed variety was 452 and 201 square centimeter. Maximum and minimum surface area in magesterial variety was 333 and 191 square centimeter. Dispersed variety were found in more number of cases. Surface area was greater in dispersed variety than in magesterial type.
