简要总结
In the last three decades , the raise in cesarean delivery rates has led to a massive increase in the incidence of the abnormally invasive placenta .Complete separation of the abnormally invasive placenta is very difficult and usually fails and this may leads to life threatening hemorrhage and other morbidities e.g injury of the urinary tract.
Antenatal diagnosis of the extent of the myometrial involvement may help in the anticipation and the planning of management eg: to proceed a conservative management or cesarean hysterectomy in case of extensive myometrial involvement . Three dimensional (3D) power Doppler ultrasound now represents a turning point for diagnosis the abnormal placentation .
详细描述
Our study aimes to detect the accuracy of 3D ultrasonography in prenatal detection of urinary bladder wall involvement in abnormally invasive placenta (AIP) at 3rd trimester of pregnancy .
All patients will be subjected to the following:
1-Written informed consent after explaining the aim of the study, procedure and possible hazards.
2-History taking includes full obstetric history, medical and surgical history. 3-Relevant physical examination.
- In all cases, detailed transabdominal and transvaginal examinations of the placenta, uterus and pelvis will be performed within 48 hours before surgery will be done by ultrasound equipment type (GE Voluson E10).
- During the ultrasound examination the following criteria will be studied:
