RESUMEN
OBJECTIVE: To compare maternal characteristics and neonatal outcome in discordant twin gestations (DT) and concordant twin gestation (CT). METHOD: Maternal and neonatal data base of live twins >25 weeks' gestation (N=351 pairs) were reviewed for antepartum complications, labor beginning, mode of delivery, neonatal complications, malformations and perinatal mortality. The chi-squared analysis and Student t-tests were used to analyze the differences between discordant and concordant premature and term twin pairs, and appropriate for gestational age (AGA) twins, separately. RESULTS: DT occurred in 15.1% of all twin pregnancies. In preterm and term DT there were significantly more elective cesareans. Growth discordance among preterm and term eutrophic twins was not connected with increased neonatal death or other complications, except higher incidence of early neurological signs in term DT. CONCLUSION: We strongly believed that prematurity and not discordant growth of eutrophic twins has important influence on neonatal outcome.
