- Abstract:
- Objective To analyze the method and value of ultrasound scoring in assessing dangerous placenta previa combined
with placenta accreta and predicting adverse pregnancy outcomes. Methods A total of 100 patients with dangerous placenta
previa and suspected placenta accreta were enrolled in this study. The degree of placenta accreta was evaluated using
ultrasound scoring, and the evaluation results were then compared with postoperative pathologic results. Results The
detection rates of adhesion type, accreta type and penetrating type by ultrasound scoring were 100.00%, 100.00% and
86.36%, respectively, and the total detection rate of dangerous placenta previa combined with placenta accreta was 95.59%.
Compared with pathologic diagnoses, there was no significant difference (P>0.05). The sensitivity and specificity of
ultrasound scoring in accreta type were 100.00% and 72.22%, and those in penetrating type were 86.36% and 100.00%. The
incidences of adverse pregnancy outcomes in accreta type and penetrating type was higher than that of adhesion type
(P<0.05), and the incidence of adverse pregnancy outcomes in penetrating type was significantly higher than that of accreta
type (100.00% vs 76.09%, P<0.05). Conclusion Ultrasound scoring can effectively predict dangerous placenta previa
combined with placenta accreta. By classifying the pathologic types, it is found that the incidence of adverse pregnancy
outcomes in penetrating type is the highest, and some preventive measures should be taken in clinical interventions.
