N/A An increased placental ratio has known to be associated with the occurrence of cardiovascular complications in adulthood among the intrauterine fetal growth restriction. A retrospective study on 202 singleton growth-restricted infants without major congenital anomalies born from Jan. 1995 to Feb. 2001 was performed to determine the relationship between placental ratio and neonatal morbidity. The cases were categorized into three groups according to the placental ratio (<1SD below the mean, within 1SD of the mean, >1SD above the mean). There were no differences in the maternal characteristics and antenatal complications except pregnancy induced hypertension between high placental ratio group and the other groups. It presented the trend that was toward the increase of placental weight and the decrease of birth weight in high placental ratio group. The infants with a high placental ratio had increasing tendencies of meconium stained amnionic fluid, hypocalcemia, phototherapy, asphyxia.

N/A Objective : To compare the obstetric complications and perinatal outcomes of twin pregnancies conceived by In Vitro Fertilization and Embryo Transfer to twin pregnancies conceived naturally. Methods : Maternal and neonatal data were reviewed for all twin pregnancies. All twin pregnancies(n=116) were divided into IVF twin pregnancyes group(n=43) and naturally conceived twin pregnancyes(n=72). The obstetric and perinatal outcomes were compared and analysed. Statistical analysis was performed using student's t-test, χ2 test, and Fisher exact test. Statistical significance was defined as p<0.05. Results : There were no significant differences in maternal age and gestational age between two groups but nulliparity was higher in IVF-ET twin group than naturally conceived twin group. Also no differences of obstetrics and perinatal outcomes were seen between two groups. Conclusion : Although twin pregnancies following IVF-ET are more likely to result in bad prognosis, in this study obstetric and perinatal outcomes are comparable to those of naturally conceived twin pregnancies.
