AbstractAccurate prediction of the risk of spontaneous preterm birth is crucial for the clinical management of patients with preterm labor. The aim of the study was to investigate whether cervical sonoelastography improves prediction of spontaneous preterm birth compared with cervical length measurement and a fetal fibronectin (fFN) test.A prospective cohort study was conducted including 64 patients with preterm labor at 23–34 weeks of gestation. Patients had an fFN test and transvaginal cervical length measurement, followed by real-time cervical sonoelastography. The ratio of nondeformable tissue to the total area of a designed region of interest was analyzed and related to the gestational week of delivery.Cervical sonoelastography and fFN test show a significant correlation with spontaneous preterm delivery (P=0.007, P=0.001), resulting in 72.7%/36% sensitivity and 73%/95% specificity. The positive predictive value (PPV) was 61.5%/81.8% and the negative predictive value was 81.8%/70%. The cervical length was not different in cases with and without term delivery (P=0.165).Cervical sonoelastography is a promising technique that can complement routine diagnostic procedures to improve prediction of preterm birth. The PPV is improved by an fFN test.

Background: Preterm birth is an important cause of perinatal morbidity and mortality and has long term health implications. Aim of this study was to predict preterm labour by Transvaginal ultrasonographic cervical length measurement in high risk asymptomatic women which may help in decision making in managing these women.Methods: This study was conducted in Department of Obstetrics and Gynecology, Mahathma Gandhi Memorial Government Hospital, Trichy from August 2016 to September 2017 in 130 antenatal women with high risk factors such as prior spontaneous preterm birth, miscarriage. Transvaginal cervical length was measured and Gestational age at which delivery occurred was correlated and results were analyzed.Results: In present study, sensitivity of transvaginal cervical length measurement (cut off cervical length <25 mm) was 70.9% and specificity was 63% in prediction of preterm labour in high risk asymptomatic women. Positive and negative predictive value of cervical length in predicting preterm labour were 63.7 %and 70% respectively.Conclusions: Transvaginal cervical length measurement can be combined with anomaly scan in high risk women to predict preterm labor and is objective, reproducible and cost effective.
