Placental specimens were reviewed from 73 singleton pregnancies of women whose offspring received electroencephalogram (EEG) studies in the neonate period. A group of 43 neonates (postconception age [PCA] 23-44 weeks) with electrically confirmed seizures in the immediate neonate period were compared with 30 healthy preterm and term infants of comparable PCA who had no electrographic seizures. Pathologic placental changes were separated: Group A consisted of chorioamnionitis, edema, meconium staining, and/or retroplacental hematoma. Group B consisted of abnormal villous maturation, infarction, and/or chronic villitis. Logistic regression analyses calculated the odds ratio of having Group A or Group B placental lesions in each neonate group as a function of increasing PCA. For the seizure group, the odds of having Group B with or without Group A placental lesions increased by a factor of 1.2 for each postconception week up to 43 weeks PCA. For a 15-week interval the odds of having Group B lesions for the seizure group increased by a factor of 12.1 (P < 0.007). Ratios were not significant for Group A lesions alone in the seizure group or for either Group B or Group A findings in the neonate group without seizures. Pathophysiologic events in utero leading to Group B rather than Group A findings are associated with electrically confirmed seizures in near-term and term infants. Group A lesions were considered more likely to have intrapartum or peripartum associations, whereas Group B lesions were considered more likely to have antepartum associations.
