Fibroids during pregnancy can be treated conservatively until natural delivery, or whether the fibroid is removed intraoperatively during a cesarean section depends on the fibroid and the patient’s condition. The effect of fibroids on pregnancy and delivery is related to the type and size of the fibroid. Submucous fibroids may cause early miscarriage; when intermural fibroids are too large, miscarriage is usually caused by deformation of the uterine cavity or insufficient blood supply to the endometrium; low-positioned fibroids may hinder the descent of the fetus, resulting in abnormal fetal position and obstruction of the birth canal; and after the delivery of the fetus, it is easy to cause postpartum hemorrhage due to the difficulty of placenta expulsion or poor contraction of the uterus. During pregnancy and puerperium, fibroids are prone to red degeneration, which may manifest as severe abdominal pain, nausea, fever, etc. Conservative treatment is usually adopted to alleviate the symptoms, and most of the uterine fibroids in pregnancy can be delivered naturally, but we should be alert to the possibility of postpartum hemorrhage; cesarean section should be carried out when fibroids obstruct the descent of the fetus, and the operation should be based on the size of the fibroids, the location and the condition of the patient to decide whether to remove the fibroids at the same time. Fibroids detected during pregnancy should be treated promptly in regular hospitals and treated accordingly under the guidance of professional physicians.
