Abstract Objective To explore the appearance of color Doppler ultrasonography in severe placental abruption. Methods A total of 238 patients with suspected placental abruption admitted to Women and Children’s Hospital of Fuyang City, Anhui Province from April 2019 to February 2021 were selected as the study subjects. Color Doppler ultrasonography was performed within 24 h after admission, the pathological diagnosis and ultrasonic manifestations of the patients were recorded, and the diagnosis results of severe placental abruption by pathology and color Doppler ultrasonography were compared. Results Fifteen cases of severe placental abruption were diagnosed by color Doppler ultrasonography, of which three cases had irregular anechoic fluid dark area between uterine wall and placenta. In five cases, the solid echo between placenta and uterine wall was similar to that of placenta, and the boundary between tissue and placenta was not clear. In four cases, there were disorderly echo masses and irregular fluid dark area between uterine wall and placenta. In two cases, hyperechoic mass and no blood flow signal were observed behind the placental margin. There was no abnormal echo between uterine wall and placenta in one case, but high echo mass without blood flow signal could be seen in other parts of placenta outside the attachment point. Among the 15 cases of severe placental abruption detected by color Doppler ultrasonography, nine cases were pathologically confirmed as severe placental abruption. The sensitivity and specificity of color Doppler ultrasound in the diagnosis of severe placental abruption were 81.82% and 97.36%, respectively. The diagnosis of severe placental abruption by color Doppler ultrasound was highly consistent with pathological diagnosis (Kappa = 0.675, P ＜ 0.05). Conclusion Color Doppler ultrasonography can provide ultrasound data reference for clinical diagnosis of severe placental abruption, which is highly consistent with pathological results and worthy of clinical promotion.
