title: The effect of cervical cerclage on pregnancy outcomes in women following conization.
abstract: OBJECTIVE
  To determine the effect of cervical cerclage on obstetrical complications and perinatal outcomes of patients following conization.
  
  
  METHODS
  A retrospective population based cohort study.
  
  
  METHODS
  Tertiary academic medical center that covers all the deliveries of the region.
  
  
  METHODS
  All patients with previous cervical conization who delivered between the years 1994-2011.
  
  
  METHODS
  A retrospective population based study.
  
  
  METHODS
  The effect of cerclage placement on the rate of preterm birth.
  
  
  RESULTS
  During the study period there were 109 deliveries of patients following a cervical conization. Cervical cerclage was placed in 22 deliveries that served as the study group and the rest (n = 87) served as the comparison group. The rate of early preterm delivery (PTD;  <34 weeks) was significantly higher in women who had a cerclage. In a logistic regression model, cerclage was found to be an independent risk factor for early PTD.
  
  
  CONCLUSIONS
  Cerclage is an independent risk factor for early PTD In patients who had a conization due to CIN.
