| Summary: | Background: Nowadays, cervical sonography is a standard procedure in maternal healthcare. According to a study, a small cervical length found early on by sonography is a reliable indicator of premature birth. Regardless of any risk factors, there is a roughly 50% chance of premature delivery before 32 weeks if the cervical length is less than 15 mm. There are several ways for cervical imaging, such as transvaginal, translabial, and transabdominal techniques.
Methods: The Department of Obstetrics & Gynecology at PIMS Hospital in Islamabad carried out this descriptive, cross-sectional validation study from February 28, 2021, to August 20, 2021. 186 women in all, aged 20–40 years, with singleton pregnancies between 24 and 32 weeks of gestation, were included. Individuals with a history of cervical surgery, cervical incompetence, or premature rupture of the membranes were not included. A 4–9 MHz ultrasound probe was used to assess the transvaginal cervical length after informed consent was obtained. In the operating room, the cervical length of each patient was measured three times, and the smallest measurement was noted. After that, participants were monitored till birth in order to evaluate results.
Results: Thirteen were false positives and 110 were real positives among TVS positive patients. 49 of the TVS negative instances were true negatives, whereas 14 were fake negatives. Overall diagnostic accuracy, sensitivity, specificity, positive predictive value, negative predictive value, and sensitivity were 88.71%, 79.03%, 89.43%, 77.78%, and 85.48%, in that order.
Conclusion: The study concludes that transvaginal cervical length measurement after cerclage is a highly accurate method for predicting preterm delivery.
