Is universal cervical length screening indicated in women with prior term birth?
To determine whether universal transvaginal ultrasound (TVU) cervical length (CL) screening is indicated in women with prior term births. ⋯ Women with prior term birth have a trend toward a lower incidence of CL ≤20 mm, compared with nulliparous women. Further studies are needed to determine whether women with prior term births should be included or excluded from TVU CL screening.
