What are the hazards of pregnancy with uterine fibroids? What are the effects of pregnancy with uterine fibroids on pregnancy

Menstrual changes, if your normal menstrual cycle changes, increased menstrual blood volume, prolonged menstruation and irregular menstruation need to be considered. The combination of pregnancy and uterine fibroids can have an adverse effect on fertility. In early pregnancy, it can cause miscarriage, especially for submucosal uterine fibroids. In the second and third trimesters, in addition to the effect of uterine fibroids on pregnancy, the effect of pregnancy on uterine fibroids also needs to be considered.

There are three types of changes in pregnancy with uterine fibroids: enlargement, no change, shrinkage or disappearance. In most cases, it is not difficult to understand that uterine fibroids will gradually increase with the increase of gestational weeks. Since the blood supply to the uterus will increase significantly after pregnancy, estrogen and progesterone can promote the growth of uterine fibroids, so ultrasound examinations after pregnancy will find that the fibroids will increase. During the growth of uterine fibroids, a small number of patients cannot keep up with the blood supply due to the rapid growth rate, resulting in ischemia and necrotic degeneration of the fibroids. The more common degenerations are cystic degeneration and red degeneration. Cystic degeneration refers to necrosis, liquefaction, and cystic tissue of the fibroid tissue, generally without obvious symptoms. Red degeneration is due to the rapid change in the volume of the fibroids, rupture of blood vessels, bleeding, and diffusion of blood into the tissue. The clinical manifestations are acute abdominal pain and fever. Examinations often reveal an increase in the volume of the fibroids. Some patients will experience a reduction or even disappearance of uterine fibroids after pregnancy. This is mainly due to necrotic degeneration, rupture of blood vessels, bleeding, and diffusion of blood into the tissue of the fibroids. The clinical manifestations are acute abdominal pain and fever. Examinations often reveal an increase in the volume of the fibroids.

If the pregnancy is complicated by uterine fibroids that are not large and do not block the birth canal, vaginal delivery is possible. Just pay attention to the contraction of the uterus after delivery. Sometimes uterine fibroids can affect uterine contractions and cause postpartum hemorrhage. However, if the fibroids block the birth canal and require a cesarean section, it is generally not recommended to remove the uterine fibroids at the same time during a cesarean section. Of course, if the fibroids are located under the uterine incision, or most of them are located under the serosa, the fibroids can also be removed. When the amount of amniotic fluid is normal, the growth and development of the fetus will always maintain a certain space, and the fibroids will not directly compress the fetus and cause deformities.

In short, the treatment principles for pregnancy complicated by uterine fibroids are generally observation and conservative treatment. After delivery, the location and size of the uterine fibroids should be re-evaluated to decide whether to perform surgical treatment.
