Pregnancy after uterine fibroid surgery is more dangerous

Generally speaking, women with uterine fibroids can get pregnant if the diameter of the fibroids is less than 4 cm. However, if the diameter of the uterine fibroids exceeds 4 cm before pregnancy and grows during pregnancy, the chances of degeneration, miscarriage, and premature birth will increase; or if the diameter of the fibroids is less than 4 cm, but the growth location is not good, such as in the uterine cavity, on the cervix, or compressing the fallopian tubes and affecting infertility, it is best to have surgery to remove the fibroids before getting pregnant. People who have undergone traumatic surgeries such as myomectomy or cesarean section may have scars on their uterus, which is medically called a scarred uterus. People with a scarred uterus must be careful during pregnancy and childbirth.

As we all know, after a woman becomes pregnant, her uterus gradually increases in size. By the time the fetus is full-term, it can even increase to 700 times its size during pregnancy. The uterine muscle fibers will also be stretched to hundreds of times until delivery, and the fetus will be delivered by strong contractions of the uterus. A normal uterus is capable of these heavy tasks, but for a scarred uterus, the uterus is relatively weak due to the reduced elasticity and toughness of local tissues and increased fragility. If pregnancy begins before the uterine wound has fully grown, as the fetus grows and develops in the uterus, the uterine scar may rupture due to excessive tension on the uterine wall, seriously endangering the safety of mother and baby.

It is recommended that patients with scarred uterus adhere to contraception and consider pregnancy 2 to 3 years after surgery. It is best to go to the hospital for a careful examination before pregnancy to ensure that the body is in good condition and the scar has healed well. Regular prenatal examinations should be performed during pregnancy. If conditions permit, hospitalization can be performed two weeks before the expected date of delivery.

The delivery method for patients with scarred uterus depends on the specific situation. If the pregnant woman is in good physical condition, the scar heals well, the thickness is within the normal range, and the fetal position and birth canal are normal, natural delivery can be attempted, otherwise a cesarean section should be performed.
