PREDICT PRETERM BIRTH BY TRANSVAGINAL SONOGRAPHIC MEASUREMENT OF CERVICAL LENGTH IN THIRD TRIMESTER

Abstract

Preterm birth was a major cause of perinatal mortality and morbidity in developed country as well as developing country. We aimed to study relationship between cervical length measured by Transvaginal sonographic (TVS) and risk of preterm delivery. Methodology: In this prospective study of 150 symptomatic antenatal women with gestational age of 28-37 weeks were recruited; as they came due to treat of preterm birth in third trimester by Transvaginal sonographic in Imam Khomeini hospital, Ahvaz city, 2013.The cervical length of pregnant women has divided into five groups; 1- cervical length < 15 millimetre, 2- cervical length 16-19 mm, 3- cervical length 20-24 mm, 4- cervical length 25-29 mm, 5- cervical length > 30 mm. Data was entered and analysed using SPSS (version 19). P-value of 0.05 was considered statistically significant. In the unvaried analysis, relative risk with 95% confidence interval has been used. Results: The mean age of patients was 28.26yars old. Relative risk in different groups of cervical length of 30 mm were 14, 9.8,6.12, 3.04 respectively. There was significant difference between these group and preterm birth (p
