Journal Title: Vajira Medical Journal: Journal of Urban Medicine - Year 2020, Vol 64, Issue 1
Abstract
Objective: To study the prevalence of short cervix in low risk singleton pregnancy. Methods: A retrospective descriptive study was conducted in 1099 low risk singleton pregnant women who came for antenatal care at 16-24 weeks of gestation during February 2016 to January 2017 by reviewing medical records. Pregnant women who had previous history of cervical incompetence, spontaneous preterm labor, preterm premature rupture of membranes (PPROM), Loop electrosurgical excision procedure (LEEP), conization and severe congenital anomaly or chromosomal abnormality were excluded. Transvaginal ultrasound for cervical length (CL) measurement referred to Society for Maternal-Fetal Medicine (SMFM) was performed. The short cervix was defined as CL less than or equal to 25 mm. Results: The mean gestational age for CL measurement was 19.68±1.62 weeks of gestation and mean CL was 37.37±6.66 mm. The prevalence for short cervix ≤25, ≤20 and ≤15 mm was 1.73, 0.27 and 0.18 %, respectively. All pregnancy that had short cervix received micronized progesterone or 17-hydroxyprogesterone caproate (17OHP-C). Arabin pessary was used in six pregnancies and no case for cervical cerclage. Most of pregnancy delivered ≥37 weeks of gestation whereas preterm delivery was 6.46% (55/852) and late preterm was occurrences 4.23% (36/852). The major cause of preterm delivery was spontaneous preterm labor 47.27% (26/852) and preterm premature rupture of membrane 30.91% (17/852). Conclusion: The prevalence of short cervix in low risk singleton pregnancy was 1.73%.
