AbstractThe objective of our study was to evaluate the correlation of the cervical length at 20–25 weeks of gestation with the incidence of spontaneous preterm delivery in twins in a country with a high incidence of preterm delivery compared to other European countries. Cervical length was measured in 262 consecutive patients. Previous preterm delivery before 34 weeks of gestation, chorionicity, maternal age, body-mass-index, smoking habit and parity were recorded as risk factors for preterm delivery. Women who were symptomatic at 20–25 weeks and who delivered because of other reasons than spontaneous labour and preterm rupture of membranes or at term were excluded. The primary outcome was incidence of preterm birth before 34 weeks. Two hundred and twenty-three patients were analyzed. Thirty-two (14%) delivered before 34 weeks. There was a significant correlation between cervical length of less than 25 mm and spontaneous delivery before 34 weeks (50% vs. 13%,p= .007). In addition, logistic regression analysis found cervical length to be the only significant predictor of spontaneous delivery before 34 weeks (OR 1.084; 95% CI 1.015; 1.159;p= .017). We conclude that the risk of severe preterm delivery in twins is high. Cervical length at mid-gestation was the only predictor of delivery before 34 weeks.

Can a 15-mm Cervical Length Cutoff Discriminate between Low and High Risk of Preterm Delivery in Women with Threatened Preterm Labor?

BACKGROUND: Owing to associated neonatal death, morbidity and impairment in later life, preterm birth is a major public health issue. Pregnant ladies presenting to the antenatal clinic were recruited in order to predict spontaneous preterm births bythe novel method of assessing the Fetal Adrenal Gland Volume (FAGV) and Adrenal Fetal ZoneEnlargement(AFZE) and comparing it with Cervical length. MATERIAL AND METHODS:This was a prospective observational study done at a tertiary hospital in Chennai.The formulae,AFZE=Gland length/Central fetal zone length and FAGV=0.523 x length x width x depth. cFAGV=fetal adrenal gland volume/estimated fetal weight =FAGV/EFW, were employed for the purpose of this study.𝛘2 or Fisher’s exact tests,Mann-Whitney or student-t test were calculated for appropriate variables. Pregnant women with uncomplicated pregnancy with gestational age between 21-34 weeks were recruited for this study. RESULTS:70 pregnant women were studied from May2019 to August 2020 and had an average age of 25 years and mean age of gestation being 27.1 weeks.26(37.1%) of these had a preterm delivery of ≤7 days.AFZE emerged as the best predictor among the three metrics with sensitivity of 100% and specificity of ~90 %.cFAGV showed ~80%/~89% sensitivity and specificity.This was in contrast to cervical length of ≤16 mm having just 55% and 60% sensitivity and specificity respectively. SUMMARY:USG estimation of AFZE and cFAGV are more reliable and accurate indicators than CL for spontaneous preterm delivery and can be used in the routine scanning of patients with early symptoms of preterm labour to plan the management more effectively.
