Jansen CHJR, Kleinrouweler CE, Kastelein AW, et al. - Given that in the majority of cases with placenta previa or a low‐lying placenta in the second trimester, a normal placental position is reached in the third trimester. Researchers here examined whether the distance between the placenta and the internal os of the cervix (IOD) in the second trimester can aid in precise prediction of the third‐trimester low‐positioned placenta. Further, they ascertained a cut‐off value at which identification of all cases of third‐trimester low‐positioned placenta can be done. In this prospective cohort study, they included 958 women who had undergone a transvaginal ultrasound examination between 18 and 24 weeks' gestation and had a low‐positioned placenta, defined as an IOD of < 20 mm. Per findings, a low‐lying placenta or placenta previa in the second trimester persists more frequently in the third trimester when the placenta is located posteriorly compared with when the location of the placenta is anterior. The cut‐off value of the distance between the placental edge and the internal os of the cervix should be lowered from 20 mm to 5 mm in cases of an anterior low‐positioned placenta in the second trimester for re‐evaluation of placental position in the third trimester.
