Abstract

The authors studied gross and histological abnormalities of placentae from 566 newborns, grouped according to birth and gestational age. The relation of hemorragic abnormalities, infections of membranes and placental tissue, chronic infections, calcifications, hydropic degeneration of villi, chorangioma, cysts, vascular lesions (endarteritis) with newborn weight, length of gestation and intrauterine growth retardation were determined. We concluded that lesions due to disturbances of placental blood flow were significantly more frequent in placentae from term newborns small for gestational age; villi hydropic degenerations were more frequent in placentae of pre-term newborns appropriate for gestational age. Chronic infections had a tendency to be greater in placentae from infants with diminished intrauterine growth. Term newborns small for gestational age had greater proportions of placental abnormalities than the other groups.
