title: Septuplet placenta: a case report.
abstract: OBJECTIVE
  On November 19, 1997, 7 liveborn infants (4 boys and 3 girls) were delivered by cesarean delivery at 30.5 weeks gestational age. The pregnancy was the result of artificial induction of ovulation.
  
  
  METHODS
  The septuplet placenta was evaluated with a standard and systematic procedure for placentas of multiple births that revealed a septamnionic, septchorionic architecture with 5 fused and 2 unfused placentas.
  
  
  RESULTS
  Each of the 7 umbilical cords contained 3 vessels. Two cords were velamentous; the remaining 5 cords were inserted eccentrically. The ratio of combined birth weights of the 7 infants to total placental weight (7.52:1) correlated with normograms of singleton and twin gestations.
  
  
  CONCLUSIONS
  This ratio and additional calculations were used for comparison and for additional clinicopathologic correlations.
