Abstract

Objectives: ultrasonography has a major role in assisting the obstetrician to evaluate the pregnant uterus. The aim of this work is to compare 3D transabdominal and 2D transvaginal ultrasound reliability in measuring the lower uterine segment thickness in pregnant women at term with previous cesarean section.Methods: this study included 100 pregnant female at gestational age between 38 – 40 weeks, with history of previous cesarean section and no history of previous operations in the uterus rather than cesarean section. Sonographic examination of lower uterine segment was performed using 3D transabdominal and 2D transvaginal ultrasound then intraoperative assessment of lower uterine segment was done.Results: both 2D vaginal and 3D abdominal ultrasound are accurate in diagnosing scar dehiscence. The best cut-off value was 3.7 mm for transvaginal ultrasound with sensitivity 84% and specificity 56%, while the cut-off value was 5.2 mm for 3D abdominal ultrasound with sensitivity 97% and specificity 74%Conclusion: 3D abdominal is more reliable in measuring the lower uterine segment thickness than 2D vaginal ultrasound.
