Abstract

Objectives: Determine the value of ultrasound signs in diagnosing placenta accreta in pregnant women with central placenta previa who had a previous cesarean section at Hanoi Obstetrics and Gynecology Hospital. Methods: This prospective study included 32 patients with central placenta previa with old cesarean section scars at Department A4 of Hanoi Obstetrics and Gynecology Hospital (from January 2021 to January 2022). Ultrasound signs in diagnosing placenta accreta were recorded and compared with postoperative pathology results. Results: The average age of pregnant women with central placenta previa and old ceserean section scars was 36.5 years old. 7 cases were diagnosed with placenta accreta without pathology postoperative diagnosis. In 25 cases of placenta accreta, there were 24 cases with preoperative diagnosis, 1 case without preoperative diagnosis, but after surgery and taking specimens, the answer was placenta accreta. Signs of loss of retroplacental clear zone were recorded the most in the study, accounting for 90.63%, followed by Lacunae signs (71.86%) and hypervascularity of the uterovesical (68.75%). Bladder wall interruption accounted for the least proportion in the study (37.5%). Conclusion: Research shows that the 7 signs mentioned in ultrasound are important in diagnosing placenta accreta. Therefore, ultrasound is the first-line tool, with much value in diagnosing, managing and monitoring placenta accreta.
