In which cases is it applied?*one. Chorionic villus sampling and amniocentesis are genetic prenatal diagnostic tests performed in early gestational weeks due to routine or second trimester screening tests during pregnancy follow-up and advances in ultrasonographic technologies. Therefore, cordocentesis is performed less frequently.
Cordocentesis can be applied if: • diagnosis of chromosomal disorders • blood diseases - anemia, thalassemia, sickle cell anemia, Rh incompatibility • infection • growth retardation
risks• The risk of miscarriage-related miscarriage is 1/50. The high rate of loss may result from the application of the procedure to impaired infants (growth retardation, anemia, hydrops) • vaginal bleeding • reduction of the baby's heart rate • infection
How to prepare?20-26. It should be applied in clinical conditions during the gestational weeks and in the hospital environment where emergency birth and neonatal intensive care unit facilities are available starting from the 26th gestational week. There is no need for a special preparation in the early period; Preliminary preparations for fasting and emergency delivery should be completed in late period applications.
During OperationAntibiotics are administered 30-60 minutes before the procedure to reduce the risk of infection. Skin is cleaned with antiseptic. Usually no anesthetic is required. A thin, long needle, accompanied by ultrasonography, passes through the skin, abdominal wall and uterus. Fetal blood is taken from the vein on the umbilical cord. During the procedure, the mother will be asked to lie still. The process will be completed in 2-5 minutes. Burning as the needle passes through the skin and cramping may be felt when entering the uterus.
After OperationFollowing cordocentesis, the baby's heart beats will be monitored by ultrasonography or birth monitor. Cramping and vaginal spotting may occur immediately after the procedure. It is recommended that the expectant mother rest on the day of the procedure. He can go back to his normal life the next day.
ResultChromosome analysis and infection tests result in 3-5 days. The doctor and genetic counselor will report your result in double detail.
