FIRST AND SECOND TRIMESTER CERVICAL LENGTH AND PREGNANCY OUTCOMES IN WOMEN AFTER ONE OR MORE PREVIOUS CESAREAN SECTION

Abstract

Aims. To compare first and second-trimester cervical length in the selected group of patients and determine the correlation between cervical length and gestational age during delivery. Methods. The study involved a retrospective analysis of 91 pregnant women who underwent first and second-trimester transvaginal ultrasonography for cervical length measurements at Kaunas Klinikos Obstetrics and Gynecology department, between 2018 11 10 and 2020 04 30. Results. Five premature births occurred, mean gestational age was 38.95±2.04 weeks (range, 25–42 weeks). There was no statistically significant correlation between cervical length in first (p = 0.071) or second (p = 0.804) trimesters and the gestational age at delivery. Correlation between cervical length in the second trimester and maternal age (p = 0.832), number of births (p = 0.500), mother’s BMI (p = 0.240) was not found. Conclusions. There was no statistically significant correlation between cervical length in the first or second trimesters and premature birth rate in a selected group of patients. Therefore, maternal age, number of prior births, BMI, did not have any statistical impact on cervical length.
