Pregnancy causes unpredictable harm, and affects reproductive health for women if not detected and treated well. Egg pregnancy is divided into two types, complete and partial egg pregnancy.

1. What is a partial egg pregnancy?

The placenta is responsible for nourishing the fetus during pregnancy. When the placenta overproduces, it grows uncontrollably to form cysts that look like eggs or bunches of grapes, so it's called an ovum.
There are 2 types of ovum pregnancy: full ovum and partial ovum. In which, incomplete ovum, also known as partial or partial ovum pregnancy, abnormal embryo, amniotic membrane, fetus may be alive or dead, and edematous placental spines.
Partial egg pregnancy with fertilization between 1 egg and 2 sperm. In this case, although the genetic information is complete, the zygote is not normal, causing an ectopic pregnancy with an abnormal embryo
Usually, partial ovum pregnancy is easy to happen, the risk is low, so after Treatment can go well.

2. Diagnosis of partial ovum pregnancy

Initially, pregnant women also have the same symptoms as a normal pregnancy. However, people who are pregnant often have very heavy morning sickness, vomiting a lot, and people are thin and pale. Some women also have edema and high blood pressure. Pregnant women will have vaginal bleeding, usually black or dark red, persistent between the 6th and 16th weeks of pregnancy. Another typical symptom of partial ovulatory pregnancy is the uterus of the pregnant woman is too large, disproportionate to the gestational age.
When there are these signs, pregnant women should visit a medical facility to know exactly if they have an ovum and whether it is a full or partial ovum.
Here, doctors will use ultrasound and test HCG levels to diagnose partial pregnancy, the accuracy of this diagnosis is 90% because it can be confused with threatened miscarriage or stillbirth. And HCG is a substance secreted by trophoblasts, and excreted in the urine of the mother, so the value may change depending on the time of testing.
To definitively diagnose ectopic pregnancy, it is necessary to rely on pathological anatomy ie curettage to remove tissue in the uterus for testing. The HCG value is one of the values ​​used to classify high-risk pregnancies. High risk means that the disease can progress to a trophoblastic cancer that requires treatment and long-term follow-up.

3. Is partial egg pregnancy dangerous?

Partial egg pregnancy in particular and ovum pregnancy in general, if not detected and treated early, will lead to many dangerous complications for pregnant women such as blood loss, malnutrition, bleeding during pregnancy or due to pregnancy. penetrates deep into the uterus causing severe intra-abdominal bleeding.
About 80% of pregnancies after curettage go well. In the remaining 20% ​​of cases, the pregnancy turns into malignant cancer and quickly metastasizes to other parts of the body, with a very high mortality rate.

4. Treatment and prevention of partial pregnancy

When you are pregnant, the usual treatment is to dilate the cervix to cure and remove the fetus from the uterus. This needs to be done early to avoid miscarriage or development of malignancy. After abortion, pregnant women continue to be monitored and tested for HCG levels every week until negative three times in a row, then once a month for 6 months. During the follow-up period should not become pregnant. In case, after partial ovum abortion, the HCG levels decrease well, after 6 months of stabilizing, it is possible to get pregnant again.
Pregnancy is a dangerous obstetric disease, with many risks of complications, so every woman needs to have certain knowledge about it to prevent it. Eating well is very important during childbearing years.
Besides, mothers need to practice family planning, do not have too many children, and give birth close together, should not give birth when they are over 35 years old. In addition, when planning a pregnancy, mothers should visit a doctor to check the risk as well as the possibility of pregnancy to take early prevention measures.
