简要总结
Cesarean Section Scar Defect(CSD) is one of the complications after cesarean section. CSD will cause many long term complications, such as abnormal uterine bleeding, infertility, uterine scar pregnancy and uterine rupture. Transvaginal ultrasound was used to detect uterine scar defects commonly. Ultrasound elastography is a modern imaging technique that has developed rapidly in recent years. Thus, this study intend to investigate the application of Ultrasound Elastography in Cesarean Section Scar Defect.
