Can uterine fibroids cause fetal arrest?

Uterine fibroids usually do not directly cause fetal arrest, but in certain circumstances they may increase the risk of fetal arrest. The treatment of uterine fibroids mainly includes factors such as location of fibroids, size of fibroids, hormonal changes during pregnancy, placental function, complications and other factors.

1. Location of fibroids

When uterine fibroids are located under the mucosa or between the muscle walls and close to the uterine cavity, they may occupy the embryo implantation space or distort the shape of the uterine cavity. This condition may interfere with the blood supply to the placenta, resulting in restricted fetal development. During pregnancy, it is necessary to closely monitor the growth rate of fibroids and fetal development. If necessary, use progesterone capsules and other drugs to stabilize the uterine environment under the guidance of a doctor.

2. Fibroid size

Fibroids with a diameter of more than 5 cm may develop red degeneration due to estrogen stimulation during pregnancy, causing severe abdominal pain and uterine contractions. Acute painful stimulation may induce uterine contractions and increase the risk of miscarriage. Acetaminophen tablets are commonly used clinically to relieve pain. In severe cases, hospitalization is required for miscarriage treatment.

3. Hormonal changes during pregnancy

Rising estrogen levels during pregnancy can promote the rapid growth of fibroids, and large fibroids may compress the fallopian tubes or cause deformation of the uterine cavity. This condition may prevent the embryo from implanting properly or limit the fetal movement space. After evaluation, your doctor may recommend the use of dydrogesterone tablets to regulate hormone levels, as well as regular ultrasound examinations.

4. Placenta function

If fibroids are located at the placental attachment site, they may affect blood and nutrient exchange between mother and fetus. Placental insufficiency may lead to fetal growth retardation or even fetal arrest. Salvia miltiorrhiza and ligustrazine injection can be used to improve uterine blood flow. Fetal heart rate monitoring and ultrasound Doppler examination need to be strengthened during pregnancy.

5. Complications

When fibroids are combined with adenomyosis or endometriosis, the uterine cavity environment is more prone to abnormal contraction and inflammatory reactions. These pathological changes may destroy the pregnancy maintenance mechanism. At this time, it is necessary to use aspirin enteric-coated tablets for anticoagulation and cefaclor dispersible tablets for anti-infection.

Before preparing for pregnancy, the condition of fibroids should be assessed through ultrasound, and changes in fibroids should be reviewed every 4 weeks during the first trimester, and strenuous exercise and heavy physical labor should be avoided. Maintain a balanced diet and supplement with folic acid, consume an appropriate amount of high-quality protein such as fish and eggs every day, and ensure a supply of fresh vegetables and fruits. If you have persistent abdominal pain or vaginal bleeding, you need to seek medical treatment immediately. If necessary, an individualized treatment plan can be developed under the joint guidance of an obstetrician and a gynecologist.
