- Asymptomatic short cervical length (CL) remains a challenging clinical scenario.
- Delivery within 1-2 weeks after diagnosis of asymptomatic short CL is rare.
Why this matters
- A short cervix (≤25 mm) is a risk factor for preterm birth.
- Optimal management of asymptomatic short CL between 23 and 28 weeks of gestation is not clear.
- These authors suggest that the timing of antenatal corticosteroid administration should be based on additional findings, including preterm pre-labour rupture of membranes and signs and symptoms of preterm labour.
- 42.9% had a short CL prior to 23 weeks, and 57.1% had a short CL between 23 and 28 weeks of gestation.
- Shorter CL was associated with a shorter time to delivery (P=.03).
- Extremely short CL (
- For all CLs, imminent delivery (
- Retrospective, cross-sectional, cohort study.
- Cohort was taken from a single centre between 2015 and 2018 (n=126).
- At this centre, routine CL screening is performed in the second trimester (18-24 weeks) during anatomical screening.
- Funding: None disclosed.
- Small sample size.
