VP46.21: Usefulness of transvaginal ultrasonography of the cervical canal in the screening of pregnant women at risk of premature labour

To determine the optimal value of cervical length and the presence of funnelling in women with preterm labour to predict preterm delivery. Transvaginal sonography were done to determine cervical length and presence of funnelling in 75 pregnant women with gestational age between 24–36 weeks who had preterm labour and were admitted to the labour room. The cervical length of women with preterm labour ranged between 10-55 mm (mean +/- SD = 30.1 + 9.9 mm). The prevalence of preterm delivery was 43.4%. The cervical length of 30 mm had the highest diagnostic performances in predicting preterm delivery, with the sensitivity 93.3%, specificity 82.0%. About 90% of women with funnelling presence had preterm delivery. These results confirm the importance of the high frequency ultrasonography transvaginal, TVS, for its predictive value and for treatment in pregnancies with risk of preterm labour.
