Abstract:
Objective: To explore the clinical value of prenatal ultrasound in diagnosis of vasa previa. Methods: The images of 65 230 pregnant women who underwent prenatal ultrasound examination were analyzed retrospectively. The accuracy of prenatal ultrasound in diagnosis of vasa previa was calculated. The delivery modes of all pregnant women and outcomes of all perinatal infants with vasa previa diagnosis were followed up. Results: Fifty-three vasa previa cases were diagnosed during the first examination using prenatal ultrasound and 10 cases were eliminated during reexamination in late pregnancy, so 43 cases were diagnosed. Finally 41 cases (41/65 230, 0.06%) were clinically confirmed. The accuracy of middle pregnancy screening (15-28 weeks) and late pregnancy (28-40 weeks) reexamination was 100%(28/28), and the accuracy of late pregnancy was 86.67%(13/15). Cesarean section surgery was performed in all 41 pregnant women, and all fetuses survived. Conclusion: Prenatal ultrasound has a high value of prenatal ultrasound in diagnosis of vasa previa.
