A comparison of pregnancy outcome of emergency modified transvaginal cervicoisthmic cerclage performed in twin and singleton pregnancies
2021
Overview
PurposeTo compare the pregnancy outcome of emergency cerclage performed in twin and singleton pregnancies.MethodsA retrospective trial was carried out in the Department of Obstetrics and Gynecology, Sir Run Run Shaw Hospital in Zhejiang, China, from January 2013 to December 2018. A total of 89 women with acute cervical incompetence underwent the emergency cerclage. Main outcome measures were gestational age at delivery and the fetal outcome.ResultsThere were 31 twin and 58 singleton pregnancies that underwent emergency cerclage. In singleton pregnancies, gestational age at delivery (31.57 ± 6.11 vs 28.81 ± 4.34, p = 0.016), and prolongation of pregnancy (8.69 ± 6.13 vs 5.41 ± 3.72, p < 0.001) were greater, and the preterm delivery rate before 34 weeks was lower (53.4% vs 80.6%, p = 0.011) compared with twin pregnancies. Fetal weight was greater in singletons than in twins (2377.3 ± 862.1 vs 1630.3 ± 557.6, p < 0.001), but the fetal survival rate was similar. The proportion of twin gestations was significantly higher in the group with preterm delivery before 34 weeks (44.6% vs 18.2%, p = 0.011) and the proportion of previous term delivery was higher in the group with delivery at or after 34 weeks (30.3% vs 12.5%, p = 0.039). The group with preterm delivery before 34 weeks had a significantly larger size of visible membranes at cerclage than the group with delivery at or after 34 weeks (2.23 ± 0.86 vs 1.64 ± 0.80, p = 0.001). In binary logistic regression analysis, twin gestations and a larger size of visible membranes were associated with an increased risk of preterm delivery.ConclusionThe pregnancy outcome of emergency cerclage appears to have a better prognosis in singleton pregnancies than in twin pregnancies, and twin pregnancy is a risk factor for preterm delivery.
