Intrauterine embryo arrest

Intrauterine pregnancy refers to the development of a fertilized egg in the uterus, which is a normal pregnancy. "Early pregnancy" refers to the "early pregnancy" stage of pregnancy, generally the period between 0-3 months of pregnancy. Intrauterine embryo arrest is definitely a huge blow to an expectant mother. Therefore, it is necessary to understand this symptom in time. Early pregnancy embryonic arrest can be avoided through treatment. Regarding intrauterine early pregnancy embryo arrest, we have the following introduction:

1. Overview

Fetal arrest refers to embryonic arrest, which is a stage of miscarriage. Ultrasound reveals that the gestational sac is underdeveloped or does not grow after 1 to 2 weeks of observation, or the fetal heartbeat disappears. With the advent of ultrasound examination, the time for clinical diagnosis of miscarriage can be significantly earlier than in the past, and it can usually be diagnosed even before the patient has symptoms of vaginal bleeding or abdominal pain. The main clinical manifestations are the disappearance of pregnancy reactions, and vaginal bleeding and abdominal pain may occur but not necessarily. Even if vaginal bleeding and abdominal pain occur later, it is still customarily called fetal arrest. The death of a fetus in the uterus after 20 weeks of pregnancy is called stillbirth.

2. Reasons

Approximately 50% of embryonic arrests occur due to chromosomal abnormalities in the embryo. It may occur when there are major risk factors for fetal arrest, including the older age of the fetus's parents, uterine malformations of the pregnant woman, pelvic infections and immune diseases; weak risk factors include previous history of spontaneous abortion, infertility and assisted reproduction, use of medications during pregnancy, exposure to caffeine/smoking/alcohol during pregnancy, obesity, and hypothyroidism.

Symptoms

1. Menopause

For women with regular menstruation, they still do not have menstruation after the usual menstrual date. For women with irregular menstruation, it is not easy to determine whether they have menopause.

2. Vaginal bleeding

There may be no bleeding; a small amount of bleeding with or without blood clots; the embryo continues to develop and may cause incomplete abortion, inevitable abortion, and heavy vaginal bleeding with or without tissue during complete abortion.

3. Abdominal pain

There may be no abdominal pain or mild lower abdominal pain or back pain; if the embryo continues to develop after arrest, inevitable miscarriage or incomplete miscarriage may occur, with paroxysmal lower abdominal pain; complete miscarriage is manifested by severe abdominal pain in a short period of time, which is quickly relieved after the embryonic tissue is completely expelled.
