title: Cervical cerclage for prevention of preterm birth in women with twin pregnancy.
abstract: OBJECTIVE
  To compare the effect of elective cervical cerclage in women with twin pregnancy on gestational age at time of delivery.
  
  
  METHODS
  In a pragmatic fashion women in Abha Maternity Hospital, Saudi Arabia with twin gestations were allocated to receive either an elective cerclage (group I) or no cerclage (group II). Elective cerclage was performed at 12 to 14 weeks of gestation after sonographic examination of the fetus to confirm gestational age and exclude major congenital anomalies. In all cases, follow up of the pregnancy was continued until delivery.
  
  
  RESULTS
  Of the 176 twin pregnancies included, cerclage was performed in 76 women, and no cerclage in 100 women. In Group I: 12 pregnancies ended in spontaneous miscarriage, 37 in preterm labor, and 27 women reached full term. There were a total of 106 live births in 62 women. In Group II: 8 women aborted, 44 women ended in preterm labor and 48 women reached full term. There were a total of 160 live births in 89 women. The gestational age at delivery ranged from 20 to 41 weeks. Multiple regression analysis did not show association between cerclage and time of delivery, although a trend was observed (P=0.056).
  
  
  CONCLUSIONS
  Elective cerclage contributes little in prolongation of gestational age at the time of delivery in women with twin pregnancy, especially in women of high parity. Those with a previous history of preterm labor may be a subgroup that could benefit from elective cerclage.
