Transvaginal Ultrasound Assessment of Cervical Length in Threatened Preterm Labor

---

Abstract Objectives: To determine the cut off point of cervical length using transvaginal ultrasonography to predict the actual occurrence of preterm labor in women with threatened preterm labor.Methods: A cross sectional study with consecutive random sampling method. We examined 80 women with singleton pregnancy complaining of regular, painful uterine contraction and ruptured membrane at 24-36 weeks of gestation. Women in active labor, defined by the presence of cervical dilatation ≥ 3 cm, and having complication were excluded. When the patient was admitted, a transvaginal scan was performed to measure the cervical length. Parenteral magnesium sulfate was given as the subsequent management. The primary outcome was delivery within 24 hours of presentation. Results: We found that the optimal cut off values for cervical length was 2.65 cm with sensitivity 94.4%, specificity 65.4%, positive predictive value 75.4% and negative predictive value 81.8%. In 69 cases, the cervical length was > 2.65 cm, with 52 patients successfully continued their pregnancy until more than 24 hours. In the 11 cases with cervical length ≤ 2.65 cm, delivery within 24 hours occurred in 9 cases (81,8%).Conclusion: The findings of this study suggest that in women with threatened preterm labor, cervical length ≤ 2.65 cm may help predict the actual occurrence of preterm labor.Keywords: cervical length, threatened preterm labor, transvaginal ultrasonography
