Are there risks of miscarriage in scar pregnancy?

The risk of scar pregnancy is still relatively high, and can be said to be as threatening as ectopic pregnancy. The so-called scar pregnancy refers to the proliferation of scars in a woman's uterus. The cause of this scar proliferation is that she has undergone a cesarean section or physical trauma. At this time, scar pregnancy can easily lead to uterine rupture. Once this happens, it can pose a threat to the life of the pregnant woman.

1. Risks

1. Scar pregnancy is as dangerous as ectopic pregnancy. If the pregnancy is not terminated in time, it may cause heavy bleeding.

2. In addition to the risk of scar pregnancy, if you become pregnant again after a cesarean section, you will also face the risk of rupture of the scar in the lower segment of the uterus. The risks of placenta previa, placenta accreta, etc. will also increase, which in turn increases the possibility of postpartum hemorrhage.

2. Occurrence rate

The chance of developing a "scar pregnancy" after a cesarean section is 5.3 times that of a woman with no history of cesarean section. In obstetric cases where the uterus needs to be removed due to severe bleeding, 20% to 30% are related to "scar pregnancy".

3. Basic Diagnosis

The reason why "scar pregnancy" is dangerous is that it is very good at "disguising itself". Due to structural abnormalities, the tissue in the uterine scar is much thinner than normal tissue and can be easily ruptured. Therefore, post-cesarean section uterine scar pregnancy is a very dangerous type of pregnancy, which is difficult to diagnose early and easy to misdiagnose.

The symptoms of "scar pregnancy" in the early pregnancy are almost the same as those of normal pregnancy, including a history of amenorrhea, enlarged uterus, positive HCG in blood and urine, and other normal early pregnancy symptoms. The difference is that patients with scar pregnancy may experience irregular vaginal bleeding after menopause. Uterine scar pregnancy can usually be detected through B-ultrasound, but this is also related to the doctor's experience. Some inexperienced doctors sometimes mistake scar pregnancy for normal intrauterine pregnancy.

Scar pregnancy is also a pregnancy disease. However, the incidence of this disease is relatively low, but the risk is relatively high. Termination of pregnancy at the scar site has certain risks, including the risk of heavy bleeding and life-threatening danger. It is very difficult because the uterus at the scar site contracts poorly and is prone to residue, and some embryonic tissue is easy to implant. Scar pregnancy is a rare but extremely dangerous obstetric emergency and a type of ectopic pregnancy. Simply put, the fetus grows to a place where it should not grow.
