Objective: Efficacy of emergency cerclage commensed in the second trimester is a controversial issue. In this study, we aimed to assess the success and associated complications of emergency cerclage in patients with cervical dilatation in the second trimester. Material and Methods: In this retrospective study, medical records of 75 pregnant women who had clinically and ultrasonographically confirmed cervical dilatation in the second trimester who had undergone cervical cerclage were analyzed. Pregnancy prolongation was the main outcome measure. Results: Seventy-five women were included to the study. Mean age was 27 and mean gravidity of the patients was three. Mean cervical length was 28.5 mm (12-41 mm). The rate of spontaneous abortion, immature deliveries, prematurity and deliveries after 34 weeks were 2.7% (n= 2), 8%(n=6), 12(n= 9) and 77.7 (n = 58), respectively. Fetal survival rate was 89.1% (n = 65). Serious vaginal bleeding from the suture area was noted in two patients (2.6%). No postoperative complications occurred. Conclusion: Emergency cerclage is a simple surgical procedure with lower complication rates and can effectively prolong gestation to viability. It can be considered as a useful measure for patients with evidence of cervical changes in the second trimester.
