[Pregnancy outcome following cerclage. 2. Multiple pregnancy].

In a retrospective study pregnancy and labour after cerclage had been studied in comparison to 160 patients with singleton pregnancies and a matched pair control group of multiple pregnancies without operative cervix closure. Cervical incompetence in multiple pregnancy observed more frequently than in singleton ones is not correlated to obstetric history, but has a bad prognosis because of necessity of tocolysis during pregnancy, marked shortening of duration of pregnancy, lowering of length and weight of newborns. An increase in frequency of amniotic infections had to be calculated following cerclage in multiple pregnancies, too. Our results especially in multiple pregnancies are not so optimistic. This statement is valid also for the indication to its prophylactic use.
