title: [Value of examining the placenta in pregnancies complicated by fetal malformations].
abstract: This investigation was undertaken to determine whether examination of the placenta contributed to a better understanding of the causes of fetal malformations. Specific histological abnormalities were found in triploidy and lysosomal storage disorders. Placentas from trisomies only showed a marked a specific retardation of villous maturation. The most frequent placental abnormalities detailed in cases presenting major fetal malformations with normal karyotype were: velamentous insertion of the umbilical cord, placental hypotrophy, single umbilical artery, marginal retroplacental hematoma and generalized perivillous fibrin deposition. Examination of the placenta after fetal malformation can provide helpful informations in counseling the parents and the perinatal team in the follow-up of any future child bearing.
