title: Impact of perinatal outcome of the presence of fused or separate placentas in dichorionic twins.
abstract: OBJECTIVE
  The aim of this study was to investigate the influence of fusion of the placentas on various obstetric and neonatal findings in dichorionic twin pregnancies.
  
  
  METHODS
  Medical charts of the total population of women who gave birth to dichorionic twin babies at the Japanese Red Cross Katsushika Maternity Hospital between 2002 and 2007 were reviewed. Data were collected from 158 deliveries with dichorionic fused placentas and from 261 deliveries with separate placentas.
  
  
  RESULTS
  There were no significant differences in various obstetric and neonatal findings between dichorionic twin pregnancies with fused placentas and those with separate placentas.
  
  
  CONCLUSIONS
  The current findings indicate that there is no significant influence of fusion of placentas in dichorionic twin pregnancies.
