Abstract
Background: Transabdominal ultrasound and transvaginal ultrasound are complementary for diagnosis; also, in situations of placenta previa, transvaginal ultrasonography is safe and enables thorough inspection of the lower uterine section. Aim and objectives: The study's objective was to compare how placental invasion was assessed using transabdominal ultrasound versus transvaginal ultrasound in patients with placenta previa anterior wall with a prior uterine scar. Subjects and methods: Between April 2021 and September 2021, 120 pregnant women with chronic placenta previa (beyond 28 weeks of pregnancy) were prospectively included into this research at the Department of Gynecology and Obstetrics, AL Azhar University Hospital. Results: Of 94 positive clear zone TVS, 70 patients showed positive clear zone by TAS. TVS accuracy was 63.3% and TAS was 78.3% in detecting retroplacental clear zone. Conclusion: Based on our findings, Transabdominal ultrasound and transvaginal ultrasound are complementary for diagnosis; also, in situations of placenta previa, transvaginal ultrasonography is safe and enables thorough inspection of the lower uterine section
