With increasing concern for the study of the fetal
aspects of pregnancy , the availability of normal standards
of placenta becomes more and more important
It is very difficult to test the functional capacity of
placenta. And for this reason anatomic studies to
determine the normal relationship between the placenta
and the newborn infant have come to be of
considerable importance. A study of morphometric
features of L 000 consecutive placentas delivered at
the Seoul National University Hospital during a period
of 2 years, from March 1978 to April 1980, in relation
to gestational age and weight of newborn was
carried out
The findings could be summarized as follows
1. The average weight and dimensions of term
placentas were 476.96gm and 20.32 X17.73X 1. 52cm.
The weight and size of placenta were progressively
increased from 24 to 40 weeks of gestation.
2. The average length of umbilical cord was 57cm
and the commonest site of insertion was eccentric.
3. The abnormal gross findings among 1, 000 placentas
included 5 cases of single umbilical artery, 37
cases of circummarginate placenta. and 3 cases of Koreanschorioangioma.
4. The frequency of chorioamnionitis was 2% in
this series.
5. Morphometric features like placental weight,
dimensions, fetoplacental ratio and placental co·effcient
showed a more significant co·relation with hirth
weight than with gestational age.
