Is there value for serial ultrasonographic assessment of cervical lengths after a cerclage?
OBJECTIVE: The objective of the study was to determine the value of serial ultrasonographic cervical length (CL) measurements after cerclage to predict preterm delivery. STUDY DESIGN: Retrospective ultrasonographic and outcome data from singleton pregnancies with cerclage were reviewed. Using transvaginal ultrasound (TVS), overall CL obtained before cerclage placement, 2 weeks after cerclage, and before delivery were compared between women who delivered preterm (less than 37 weeks) and term. The overall CL including CL above (CLA) and below the cerclage (CLB) were compared using the SAS program. RESULTS: Cerclage was placed at 15.7 +/- 3.6 weeks (mean +/- SD) in 57 women. The overall CL before cerclage, 2 weeks after cerclage, and the last TVS before delivery was not different in preterm and term births. The odds ratio of a measurable CLA for preterm delivery by TVS was 0.87 (0.78 to 0.95, 95% confidence interval). Thirty-two patients (56%) had absent CLA at 26.7 +/- 4.4 weeks. Of thes
