Objective:
The purpose of this study was to evaluate the clinical utility of cerclage in low risk women with cervical length (CL) < or = 25 mm at transvaginal ultrasound (TVU).
Study Design:
This was a retrospective cohort study of women with CL < or = 25 mm identified incidentally at TVU examinations between 16(0/7) to 24(6/7) weeks, with no history of previous preterm birth or midtrimester losses. The primary study outcome was rate of preterm delivery < 35 weeks' gestation.
Results:
Women undergoing cerclage placement (n = 31) had shorter CL (P < .001) and lower gestational age at presentation (P < .001) than those managed with rest alone (n = 36). Gestational age at delivery was 37.6 +/- 3.6 vs 38.5 +/- 2.1 weeks (P = .17), and delivery at < 35 weeks occurred in 5/31 versus 2/36 cases, respectively (P = .23). The lack of a significant association between cerclage and rate of delivery < 35 weeks persisted after controlling for gestational age at TVU and initial CL (P = .81).
Conclusion:
Cerclage placement does not improve pregnancy outcome in low-risk women with incidental detection of CL < or = 25 mm in the early second trimester.
