During pregnancy, some women must undergo amniocentesis. Some women do not need to do it when they are pregnant. Amniotic fluid puncture is also a relatively dangerous surgery. If the puncture is not successful, it may affect the health of the fetus and even lead to miscarriage. What is amniocentesis surgery? What can be detected by amniocentesis?
Amniotic fluid puncture can not only detect Down syndrome, but also check whether the fetus is deformed, whether the limbs, body organs, etc. are fully developed, and can also check the maturity of the fetus. Amniotic fluid aspiration can also be used for paternity testing. By extracting amniotic fluid from the uterus, fetal DNA cells can be extracted for paternity testing.
Amniotic fluid puncture carries certain risks, as it may cause miscarriage, amniotic fluid leakage, and other situations. Amniotic fluid aspiration examination is a method of prenatal diagnosis that is generally suitable for mid-term pregnancy. In order to minimize miscarriage after amniocentesis, doctors will inquire about the medical history in detail and conduct necessary preoperative examinations before the puncture.
Amniotic fluid puncture is mainly guided by ultrasound to insert a slender needle through the pregnant woman's abdomen and uterine wall, and then enter the amniotic fluid cavity to extract some amniotic fluid. Therefore, amniocentesis needs to be performed under the guidance of ultrasound. It is best to do amniocentesis between 16 and 20 weeks in advance.
