Placental implantation refers to the invasion of placental villi into part of uterine myometrium. Placenta is like a tree with roots, intricately dispersed and deeply rooted in the myometrium of uterus. Placenta implantation part cannot be peeled off by itself, and manual peeling will damage the myometrium of uterus. Pathological microscope showed that villi invaded the myometrium of uterus. Placenta implantation is a rare and serious complication in obstetrics, which can lead to massive hemorrhage, shock, uterine perforation, secondary infection and even death. In the past, the uterus was often removed urgently to save the patient's life. Placenta implantation ...

2. Placenta implantation is very common:

Placenta implantation is common after endometrial trauma or inflammatory injury or scar formation, so it is easy to have a history of induced abortion, curettage, cesarean section, manual placental abruption, previous history of placenta implantation or placenta previa, endometritis, local mucosal atrophy of submucosal myoma, multipara, primipara with pregnancy age ≥35 years, and after radiotherapy. At present, abortion and cesarean section are considered to be important reasons for placenta implantation.

3. Considering that pregnant women with placenta implantation are more likely to have placenta implantation after pregnancy than other pregnant women, there is a risk of placenta implantation. Therefore, it is recommended that you have regular pregnancy check-ups, strictly detect the development of the fetus, and try to avoid late childbirth.

Placenta implantation examination has three points:

Auxiliary diagnosis: ①B-ultrasound (preferred): the boundary between placenta and uterus attachment surface is unclear; The cavity inside the placenta can be seen on the contact surface; Abnormal blood flow enters the myometrium of uterus. ② Magnetic resonance imaging: It is valuable to know the degree of placenta implantation and whether it invades adjacent organs. ③ Endoscopic examination: Placenta implantation can penetrate the uterus to serosa, involving the bladder forward and the sigmoid colon backward. Laparoscopic, cystoscopy and sigmoid colon examination are feasible for suspicious cases.
