Amniocentesis is a medical procedure used primarily in the prenatal diagnosis of genetic conditions. [1] It has other uses such as in the assessment of infection and fetal lung maturity. [ 2 ] Prenatal diagnostic testing, which includes amniocentesis, is necessary to conclusively diagnose the majority of genetic disorders, with amniocentesis ...
An amniocentesis is a procedure in which a sample of amniotic fluid is aspirated using a needle that is inserted into the abdomen guided by ultrasound. [1] The sample is then tested, and can help doctors diagnose genetic disorders, birth defects, or other fetal health problems.
Amniotic fluid is removed from the mother by an amniocentesis procedure, where a long needle is inserted through the abdomen into the amniotic sac, using ultrasound guidance such that the fetus is not harmed. Amniocentesis is a low risk procedure, with risk of pregnancy loss between 1 in 1,500 – 1 in 700 procedures.
Fetoscopy is an endoscopic procedure during pregnancy to allow surgical access to the fetus, the amniotic cavity, the umbilical cord, and the fetal side of the placenta.A small (3–4 mm) incision is made in the abdomen, and an endoscope is inserted through the abdominal wall and uterus into the amniotic cavity.
Prenatal diagnosis focuses on pursuing additional detailed information once a particular problem has been found, and can sometimes be more invasive. The most common screening procedures are routine ultrasounds, blood tests, and blood pressure measurement. Common diagnosis procedures include amniocentesis and chorionic villus sampling.
The procedure relies primarily on either a pair of curved forceps blades or a vacuum extractor that applies negative pressure inside the womb. The forceps are designed to reach the top of the fetal head and create the necessary traction to pull and rotate the baby out.
Assisted reproductive technology (ART) includes medical procedures used primarily to address infertility. This subject involves procedures such as in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), and cryopreservation of gametes and embryos, and the use of fertility medication.
An Intrauterine transfusion (IUT) is a procedure that provides blood to a fetus, most commonly through the umbilical cord. [1] [2] It is used in cases of severe fetal anemia, such as when fetal red blood cells are being destroyed by maternal antibodies, or parvovirus B19 infection, homozygous alpha-thalassemia, or twin-to-twin transfusion syndrome.
