Conservative treatment of scar pregnancy, it turns out these are the symptoms

Scar pregnancy refers to a situation in which a woman who has had a history of cesarean section becomes pregnant again and the fetus is located in the uterine scar, which often leads to heavy vaginal bleeding and late uterine rupture, and is as dangerous as an ectopic pregnancy. Currently, drug therapy, uterine artery embolization and surgical treatment are the most common conservative treatments for scar pregnancy.

1. What are the clinical manifestations of uterine scar pregnancy?

She had a history of cesarean section before, and this pregnancy was accompanied by irregular vaginal bleeding. Vaginal bleeding can be more or less, sometimes sudden heavy bleeding, and sometimes no vaginal bleeding. There is usually no obvious abdominal pain, or only mild abdominal pain. Asymptomatic people are easily missed.

2. How to treat uterine scar pregnancy?

Since scars can have serious adverse consequences, pregnancy must be terminated promptly once diagnosed. There is currently no unified treatment plan.

1. Drug treatment

Methotrexate and mifepristone are currently commonly used drugs. The purpose is to stop the development of the embryo and reduce the blood supply to the placenta, thereby reducing bleeding during medical abortion or surgery. Methotrexate is a chemotherapy drug with many side effects, some of which can cause severe bone marrow suppression. We tend to use mifepristone plus traditional Chinese medicine for treatment. After 1-2 weeks of use, most embryos stop developing and the blood supply to the placenta is significantly reduced. Misoprostol is then used for abortion or uterine curettage, which is mostly successful with low cost and minimal trauma.

2. Uterine artery embolization

It is an interventional treatment method that performs unilateral or bilateral uterine artery embolization via the femoral artery, followed by elective uterine curettage. This method is relatively expensive, has many side effects of embolization, and the timing of uterine curettage is difficult to grasp.

3. Surgical treatment

Through laparotomy or minimally invasive surgery: local lesion resection + uterine repair, + hysterectomy if necessary. Surgical treatment is safe and effective, but it is traumatic and expensive, so it should not be used as the first choice and can only be used as a supplement when other methods are ineffective.
