Abstract
Objective: To compare the accuracy of two-dimensional (2D) and three-dimensional (3D) Trans-abdominal ultrasonography in the prediction of cesarean scar dehiscence in pregnant women at term. Design: A prospective cohort study. Setting: Cairo University Teaching Hospital. Methods: 100 patients was recruited from In-patient wards and outpatient clinics from September 2018 until March 2019. 2D and 3D transabdominal ultrasound was performed and the measurements were then correlated to scar integrity assessed intraoperatively. The data was then statistically analyzed. Main outcome measure: Accuracy of 2D and 3D US in predicting uterine scar dehiscence. Results: The mean scar thickness as measured by 3D TAS in the third trimester for patients with a dehiscent scar was 3.05±0.75 mm with a best cut-off level for predicting uterine scar defects of {u2264} 3.976 mm (highest diagnostic accuracy) with sensitivity 100%, specificity 70.5%. The area under the curve was 85.1%
