Two and Three Dimensional Ultrasound Assessment of Cesarean Section Scars in Pregnant Women with Previous One or Two Cesarean Section and Its Correlation to Intraoperative Findings

The risk of uterine scar dehiscence and uterine rupture is inversely related to the lower uterine segment (LUS) thickness as measured by ultrasound. Three dimensional ultrasound can increase the reliability of ultrasound in prediction of scar dehiscence. Transvaginal three dimensional ultrasound measurement of the muscular layer thickness of the lower uterine segment seems to be the most reliable method for prediction of scar dehiscence. Cesarean section rate has been rising continuously over the last few decades. This rise has become a challenge to the obstetricians all over the world as many obstetric complications are getting more and more common due to increased percentage of obstetric population with preevious Cesarean sections including uterine rupture and abnormal placentation.
