A case report of placental infarction.

A 31-year-old Japanese female, gravida 4, para 0, who had previously experienced three spontaneous abortions during 7 th or 8 th month of gestation was diagnosed with intrauterine fetal death at 26th weeks of gestational age. Investigations for maternal and fetal etiologies, including toxemia, incompatibility of blood groups and types, and infections, proved negative. Anoxia which resulted in the demise of the fetus is believed to have been responsible for the rare combination of extensive placental infarction in an asymptomatic gravid woman.
