Objective: To examine the value of the cervical length (CL) measurement at 24-30 gestational weeks in the prediction of spontaneous preterm delivery (SPD) between 30 and 34 weeks (SPD34) and between 34 and 37 weeks (SPD37). Methods: We performed a prospective cross-sectional study. CL was measured once by transvaginal ultrasound examination between 24 and 30 weeks. Results: The study sample consisted of 1,180 low-risk singleton pregnancies. 10 women (0.85%) had a SPD34 and 60 (5.08%) had a SPD37. CL was shorter (p < 0.001) in the women who had a SPD34 (median 11 mm) compared to the women who delivered after 34 weeks (median 31 mm). CL was shorter (p < 0.001) in the women who had a SPD37 (median 22 mm) compared to the women who delivered after 37 weeks (median 31 mm). CL predicted SPD34 (OR = 0.837, R2 = 0.2768, AUC = 0.9406, p < 0.001) and SPD37 (OR = 0.907, R2 = 0.1085, AUC = 0.7584, p < 0.001). The model achieved a sensitivity of 70.0 and 38.3% for 10% false-positive rate for SPD34 and SPD37, respectively. Conclusions: CL after 24 weeks is significantly shorter in women destined to have a SPD. In low-risk singleton pregnancies CL performs very well in predicting SPD34 and adequately in predicting SPD37.

Objective: A short cervix during pregnancy indicates a higher risk of preterm delivery. Transvaginal sonography is widely used for the detection of a short cervix. The literature indicates that 21–24 weeks is the most sensitive gestational age to assess transvaginal cervical length (TV CL) of ≤2.5 cm for potential preterm delivery. Pregnancies between 18 and 20 weeks’ gestation are generally performed transabdominally; thus, it could be beneficial to have a recognized correlation between the transabdominal cervical length (TA CL) measurement and the TV CL measurement at this earlier time period. Materials and Methods: An online database search produced 13 research articles to be reviewed. Inclusion criteria consisted of TA CL and TV CL assessment of singleton pregnancies with intact membranes. Results: Findings indicate high diagnostic yield when a TA CL of <2.9 cm or TV CL of <2.5 cm is used for defining a shortened cervix when measured between 18 and 20 weeks’ gestation. Conclusion: This review of the literature indicates a correlation between average TA CL and average TV CL measurements, although the relationship widens as CLs become shorter.

Preterm delivery (PTD), defined as birth before 37 completed weeks of gestation, is the leading cause of perinatal morbidity and mortality. Evaluation of the cervical morphology and biometry with transvaginal ultrasonography at 16–24 weeks of gestation is a useful tool to predict the risk of preterm birth in low- and high-risk singleton pregnancies. For instance, a sonographic cervical length (CL) > 30 mm and present cervical gland area have a 96-97% negative predictive value for preterm delivery at <37 weeks. Available evidence supports the use of progesterone to women with cervical length ≤25 mm, irrespective of other risk factors. In women with prior spontaneous PTD with asymptomatic cervical shortening (CL ≤ 25 mm), prophylactic cerclage procedure must be performed and weekly to every two weeks follow-up is essential. This article reviews the evidence in support of the clinical introduction of transvaginal sonography for both the prediction and management of spontaneous preterm labour.

AbstractPartoSure is a bedside test for the prediction of time-to-spontaneous preterm delivery by the detection of placental alpha microglobulin-1 (PAMG-1). The objectives of this study were to further determine the test’s efficacy in predicting delivery within 7 or 14 days from testing, and to compare it with fetal fibronectin (fFN) and cervical length (CL) measurement by transvaginal ultrasound.The study population consisted of 203 consecutively recruited women with singleton pregnancies between 20The sensitivities for PartoSure (n=203), fFN (n=66), and CL (n=203) for predicting imminent spontaneous preterm delivery within 7 days were 80%, 50%, and 57%, respectively. The specificities were 95%, 72%, and 73% for PartoSure, fFN and CL, respectively. The NPVs were 96%, 87%, and 89% for PartoSure, fFN and CL, respectively. The PPVs were 76%, 29%, and 30% for PartoSure, fFN and CL, respectively.PAMG-1 detection by PartoSure is the single best predictor of imminent spontaneous delivery within 7 days compared to fFN and CL. In settings where CL is used as an initial screen, PartoSure has the greatest clinical utility in patients with CL between 15 and 35 mm. In situations where CL is not an initial screen, PartoSure is the most accurate test compared to fFN and CL.

Introduction: To compare the effect of a policy of screening for spontaneous preterm delivery (SPD) by transvaginal cervical length (CL) measurement versus a no screening policy in the prevention of severe prematurity. Methods: Retrospective study on low risk singleton pregnancies examined at 20-24 weeks. Two cohorts one with SPD screening and the other without screening were matched using propensity analysis to create the study groups. Women with short CL were treated with vaginal progesterone and/or cervical cerclage/pessary. The outcomes examined were SPD<32 weeks (SPD 32) and SPD between 20 and 32 weeks (SPD 20-32). Results: Screening for SPD was associated with a significant reduction in the rate of SPD at less than 32 weeks (0.3% vs 0.8%, p=0.001 in the screened and no screened pregnancies respectively) and in the rate of SPD 20-32 (0.3% vs 0.9%, p=0.005 in the screened and no screened pregnancies respectively). After adjusting for maternal age, parity, body mass index, smoking and mode of conception, the screening group had significantly lower hazard for SPD 20-32 (HR=0.36, 95% CI: 0.18-0.75, p=0.006) and SPD32 (HR=0.39, 95% CI: 0.19-0.82, p=0.013). Conclusion: Screening for SPD by transvaginal CL measurement in mid pregnancy may reduce the incidence of severe prematurity in low risk singleton pregnancies.
