What is a villus tissue biopsy?
Villus tissue is part of the body tissue of a pregnant child from which it can be clearly and accurately checked whether the entire fetus is genetically normal or abnormal, and because it is readily available, it is used as a means of prenatal diagnosis. To help the doctor know if the fetus is normal.
Who needs to have a villus tissue biopsy?
A woman who has had a child with a genetic disease has a certain chance of re-emerging hereditary disease. Therefore, the doctor will advise her to perform a villus tissue biopsy within 7 to 9 weeks of the first trimester of pregnancy. If the result is not normal, the pregnancy can be terminated in time within 3 months of pregnancy, and it is easier to terminate the pregnancy at this time.
Is there any risk of villus tissue biopsy?
This operation can be checked through the vagina or through the abdomen. The operation itself, pregnant women have no pain, only individual pregnant women may be aborted due to operational stimulation, or sometimes cause trauma, etc., doctors need to pay great attention, in the case of continuous improvement, these risks will gradually reduce.
Special recommendation: Does pelvic inflammatory disease affect fertility?
Pelvic inflammatory disease refers to the inflammation of the peritoneal surface in the pelvic cavity, which is caused by the spread and development of suppurative inflammation of the cervical canal, uterus and fallopian tube. Of course, it can also be caused by the spread of appendicitis and enteritis. When the inflammation is severe, an abscess can be formed between the uterus and the rectum. After the inflammation subsides, it can cause adhesion and change the relationship between the ovary and the fallopian tube, causing adhesion and closure of the umbrella of the fallopian tube, so that the capsule on the surface of the ovary thickens and hardens. The egg can not be discharged normally, or it can cause infertility because it affects the delivery function of the fallopian tube.
- Therefore, pelvic inflammatory disease must strive to be treated in the acute phase, the dose of antibiotics should be large, use antibiotics sensitive to bacteria, it is best to do bacterial sensitivity test. For the abscess that has been formed, the pus should be drained early and the cortisone drug should be used to reduce the adhesion. After the acute inflammation subsides, the tubal fluid should be used to prevent and treat the fallopian tube adhesion. For the infertility caused by the adhesion of chronic pelvic inflammatory disease, the fallopian tube can be repeatedly used for ventilation and ventilation, and the ineffective one should be used for adhesion surgery or fallopian tube. Forming surgery. Although the concept of prenatal care is very common, the news of births with congenital diseases or unhealthy babies is still heard. Is there any focus on prenatal care?
- Prenatal examinations should start around ten weeks of pregnancy, but in fact, it is best to go to the hospital two weeks after the menstruation has not come to determine whether you are pregnant. There are two purposes: if you confirm pregnancy, some things should be paid special attention. If medication should be used cautiously, some medical examinations such as X-ray examination should avoid and maintain regular diet and daily life. On the other hand, ultrasound examination can be used to confirm that the embryo is indeed implanted in the uterine cavity and understand the embryo. Developmental situation.
- If the embryo is not in the uterine cavity, there are two possibilities, one may be ectopic pregnancy, which is a very serious situation, which may endanger the safety of pregnant women; the other may be atrophy, that is, abnormal embryos, it is likely to abort At this time, the doctor can make a differential diagnosis to ensure the safety of the expectant mother. Only one ultrasound examination can be performed during the entire pregnancy process, which shows that this should not be enough.
- The first antenatal check-up is about ten weeks pregnant, and some blood and urine tests will be started to understand the basic physical condition of the pregnant woman, such as diabetes, kidney disease, or Mediterranean anemia.
- If the expectant mother has Mediterranean-type anemia, he should take a blood test for the prospective father as soon as possible to determine if he also has Mediterranean-type anemia. If both parents have it, one-fourth of the baby born in the future may have severe Mediterranean-type anemia. Special attention should be paid throughout the pregnancy. Should also pay attention to the possibility of having twins or even a baby? Ultrasound examination should be made at this time.
- For about 16 weeks of pregnancy, for older women over the age of 34, doctors generally recommend amniocentesis. If the fetus has chromosomal abnormalities such as Down's syndrome, it can be detected early. Up to now, this is the most accurate method for diagnosing fetal chromosomal abnormalities such as Down's syndrome, but it is not encouraged for every pregnant woman. Because amniocentesis is an invasive test, the abortion rate is about 100%. First, not too low.
However, pregnant women under the age of 34 may still have a baby with Down's syndrome. They can take blood for screening for Down's disease and screening for neural tube defects. Check for fetal type A fetal globulin or placental villus hormone in the mother's blood. In order to detect its abnormal probability, if the probability is high, it is recommended to perform amniocentesis. If the probability is not high, it can be observed by ultrasound. In addition, observing the proper placement of the fetus and the amount of amniotic fluid can also be used as a guide for the health of the fetus.
