[Morphology of the placenta in relation to glycemia status in pregnancy in diabetes mellitus].

Morphological investigations in 569 placentas of diabetic women have been performed. The histological results of 300 placentas from diabetic women delivered between 1969 and 1973 were compared to 269 placentas of diabetic women from the time period 1979 to 1983. The latest time period was characterised by normoglycemic metabolic control throughout pregnancy. Besides the morphological findings clinical results especially the perinatal mortality and morbidity during the two time periods are discussed. Morphological changes in the placenta of diabetic women are depending one the quality of metabolic control during pregnancy, independing on the White classes. Normoglycemia reduces placental maturation disorders, perinatal mortality and morbidity.
