Cervical length surveillance for predicting spontaneous preterm birth in women with uterine anomalies: A cohort study

Abstract

Introduction: Uterine anomalies occur in an estimated 5% of women and have been shown to confer a higher risk of spontaneous preterm birth (SPTB). A sonographically short cervix (<25 mm) is a risk indicator for SPTB, although its predictive utility has been little studied in this specific high-risk population. We aimed to assess the pregnancy outcomes and predictive ability of short cervix in a cohort of women with uterine anomalies attending a high-risk antenatal clinic. Material and methods: This historical cohort study assessed all pregnancies in women with congenital uterine anomalies referred to the Preterm labor Clinic at the Royal Women’s Hospital, Melbourne, Australia, between 2004 a..
