The clinical value of prenatal assessment of cervical length and placental thickness in pregnant women with placenta previa

摘要

Objective: This study was designed to investigate the clinical value of prenatal assessment of cervical length (CL) and placental thickness (PT) in pregnancy outcome and prognosis of pregnant women with placenta previa. Methods: Eighty pregnant women with placenta previa treated in our hospital were enrolled for prenatal assessment of CL and PT, and were grouped as CL ≤ 30 mm (n=32) and CL 30 mm (n=48) groups and PT ≥ 10 mm (n=34) and PT 30 mm group ( P 0.05). The pregnancy and perinatal outcomes of PT ≥ 10 mm group were also significantly inferior to those of PT 10 mm group ( P 0.05). PT and CL had good predictive values for preterm delivery ( P 0.05), with high diagnostic sensitivity, specificity and accuracy. Conclusion: Prenatal assessment of CL and PT has practical clinical significance for pregnant women with placenta previa, which helps in assessing pregnancy and perinatal outcomes and is worthy of clinical application.
