RESUMO
The nosological structure of mortality was studied among low-weight fetuses, by analyzing 667 autopsy protocols over 2006-2008. There were 255 cases of spontaneous miscarriage and 412 cases of medically indicated abortion. Spontaneous and artificial abortions most frequently occur in repeated pregnant women at 26-27 weeks gestational age. In the nosological structure of fetal mortality, intrauterine fetal asphyxia was most commonly in spontaneous miscarriage; intrauterine pneumonias and generalized infection ranked second; in artificial abortion, the number of congenital malformations doubled and that of intrauterine fetal asphyxia reduced. In spontaneous and artificial abortions, the incidence of decompensated chronic placental insufficiency increased by twice.
