Causes of stillbirth: a clinicopathological study of 243 patients.

The clinical and autopsy findings in all stillbirths during the years 1974-1979 at the Helsinki University Central Hospital were analysed. There were 243 stillborn infants of whom 200 died before labour. According to the autopsy findings asphyxia accounted for 38% and major malformations for 17% of the deaths, but because of fetal maceration no diagnosis could be made at autopsy in 43%. The cause of death suggested by the clinical findings was placental failure in 57%, cord complication in 12% and major malformations in 17%. The cause of death remained unsolved in 9%. The importance of routine ultrasound and alpha-fetoprotein screening for the detection of unrecognized risk patients is emphasized.
