title: [Clinical analysis of multiple pregnancy reduction].
abstract: OBJECTIVE
  To analyse the effect of the reduction of multiple pregnancy through transvaginal ultrasonic monitoring on the pregnancy outcome.
  
  
  METHODS
  Eighty-four cases were divided into two groups according to whether they had vaginal hemorrhage before operation. And the pregnancy outcomes were analyzed.
  
  
  RESULTS
  The abortion rate and preterm birth rate of the vaginal hemorrhage group were higher, and the difference was statistically significant.
  
  
  CONCLUSIONS
  The reduction of multiple pregnancy through transvaginal ultrasonic monitoring is a safe operative method. But it is only a remedial treatment for multiple pregnancy, and how to prevent multiple pregnancy is of more practical value.
