[Sonographically detectable changes in placental structures in pregnancy. 6. Effect of sonographic placental morphology on premature labor and intrauterine growth retardation].
Influence of sonographically demonstrable changes of placental structure on prematurity and intrauterine retardation was analysed and concerning its statistical rehability in 807 gravids. While the stages 0 and 1 don't effect prematurity and intrauterine retardation, the stage 2 is accompanied premature infant of normal birthweight if proved before the 32nd week of pregnancy. If stage 3 appears before the 34. week of pregnancy we found in 30.6% a small for date newborn, in 64% a normal weight and in 80% a small for date premature newborn. In comparison with the normal weight newborn the difference is statistically significant with an error probability of alpha = 0.05.
