How long does it take to find scars during pregnancy?

If a woman becomes pregnant again after a caesarean section, she should be alert to scar pregnancy and go to the hospital for a good examination and diagnosis in time. She can use ultrasound to check the attachment position 6 to 7 weeks after the next pregnancy to see whether a scar is formed. In addition, it is recommended that it is best to wait two years after a caesarean section before getting pregnant, which can reduce the possibility of scar pregnancy.

Scar pregnancy refers to a situation in which a gestational sac implants on the original uterine scar during the next pregnancy in a woman with a history of cesarean section. This often leads to heavy vaginal bleeding and late uterine rupture. It is an abnormal pregnancy that has become more difficult to treat in recent years.

Scar pregnancy is a rare but extremely dangerous obstetric emergency. "Scar pregnancy is a type of ectopic pregnancy. Simply put, the fetus grows to a place where it shouldn't grow. It is even more dangerous than an ectopic pregnancy."

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. If the pregnancy continues, it often leads to uterine rupture. If an artificial abortion is performed to terminate the pregnancy, it will cause heavy bleeding. If rescue is not timely, some patients will need to have their uterus removed, and even their lives will be in danger.

Relevant data show that the chance of developing a scar pregnancy after a cesarean section is 5.3 times that of having no history of cesarean section. In obstetric cases where hysterectomy is required due to severe bleeding, 20% to 30% are related to scar pregnancy.

Once it is confirmed that the embryo has implanted in the uterine scar, the pregnancy should be terminated as soon as possible. However, since patients with scar pregnancy are often misdiagnosed as intrauterine pregnancy in the early stages, some private hospitals will blindly perform surgical or medical abortions on the mothers. In this case, the villi or placenta often cannot be completely separated and the blood vessels cannot be closed, leading to heavy bleeding.

Pregnant women must carefully choose the first delivery method and should not choose cesarean section easily; women who have undergone cesarean section should take contraceptive measures to prevent unwanted pregnancy; high-risk pregnant women with a history of cesarean section should undergo vaginal ultrasound examination in early pregnancy to determine the site of embryo attachment. If it is a scar pregnancy, the diagnosis should be made as soon as possible and the pregnancy should be terminated.
