Abstract

Objective: Evaluation of thecervical lengthin 3500pregnancies at 19-23-week 6 day’ gestationbytransvaginal ultrasound. Subject and methods: A descriptive cross-sectional study involved 3500pregnancies at 19-23week 6 day’ gestation meeting the inclusive and exclusive criteria was implemented at Outpatient Department of National Hospital of Obstetrics and Gynecology (NHOG) from 02/2019 to 03/2021. Participants were clinically examined, underwent fetal ultrasound examination, and the cervical length was measured and collected. Results: The mean of cervical length of 3500 participants at 19-23week 6 day’ gestation was 35,8±5,5mm, with nosignificant difference among weeks. In the previousterm birth group, the mean of cervical length was 36,5±5,7mm, while in the group with previous preterm birth, the datum was35,2±6,3 mm. This difference was statistically significant with P<0,05. The risk of preterm birth in the group with cervical length ≤25mm was 4 times higher than that in the normal group (OR=4; 95% CI:2,2-7,6). The ratio of participants with short cervical length amounted to 1,9% (65 people). Conclusion: The mean of cervical length at 19-23week’ gestation was 35,8±5,5mmThe cervical length in group with previous preterm birth was shorter than that in the term birth group with a statistically significant difference. The amount of cervical length ≤25mm accounted for 1,9%.
