What Examinations Are Needed for Fetal Arrest?

In general, embryonic arrest refers to the cessation of embryonic development due to certain causes during early pregnancy, eventually leading to miscarriage. To evaluate embryonic arrest, the following examinations are usually recommended: endocrine testing, B-ultrasound scanning, blood HCG measurement, immunological testing, and genetic testing.

1. Endocrine Testing: This includes assessing thyroid function and levels of sex hormones (such as estrogen, progesterone, FSH, LH), to rule out hormonal imbalances as a cause of embryonic arrest.

2. B-ultrasound Examination: Using B-ultrasound to observe whether there is still fetal cardiac activity and fetal bud within the gestational sac. If symptoms such as vaginal bleeding and abdominal pain are present and ultrasound reveals no fetal heart or bud, embryonic arrest can be diagnosed.

3. Blood HCG Measurement: Measuring the level of human chorionic gonadotropin (hCG) in the blood. A continuously declining hCG level over several days can support the diagnosis of embryonic arrest.

4. Immunological Testing: Checking for the presence of anti-sperm antibodies, anti-endometrial antibodies, anti-phospholipid antibodies, etc., as abnormal immune responses may affect embryo implantation and development.

5. Genetic Testing: Chromosomal karyotyping for both partners to determine whether any chromosomal abnormalities exist, as these are a common cause of embryonic arrest.

Through the above examinations, doctors can gain a more comprehensive understanding of the causes of embryonic arrest, formulate individualized treatment plans, and help prevent similar situations in future pregnancies.
