Pregnancy Anomaly Scans
Pregnant women want to give birth to a healthy child without any structural problems. Society in general the risk of having a child with major malformations is 3-5%. Screening tests for fetal abnormalities by ultrasound and biochemical skills in terms of both the increased complexity of both physician and patient importance is growing. 11-14 of gestation. a routine ultrasound examination between weeks one of the most common indications are: evaluation of the embryo is alive, gestational age determination, the determination and the determination of the type of multiple pregnancies, depending on the measurement nuchal translucency, chromosomal anomaly in the baby making a call, 11-14. currently the diagnosis of fetal chromosomal anomalies between weeks ultrasound laboratory tests conducted in conjunction with the most important data that can be used in. Evaluation of fetal anomalies; technological developments, especially high-frequency transvaginal ultrasonography in the diagnosis of many serious fetal structural abnormalities, and 14 of gestation. the week before, are possible.
Assignment of pregnancy; pregnancy week by determination of the last menstrual period is generally an unreliable method. Women, only 40% reported that they were sure of last menstrual date. Even though they were sure of pregnancy compared with the findings of ultrasonography it has been seen more often than not have a full week. Prolonged pregnancy and higher gestational age compared to the last menstrual period be specified as the rate increases. Estimation of gestational age gestational age by last menstrual date and creates a predisposition to both random error of the determination are systematically higher. This situation is most likely late ovulation depends on. Determination and identification of the gestational sac before 6 weeks pregnancy according to the dimensions are made. Gestational age is related to the size of the gestational sac.
Binary Test; 11-14. there are some serum markers in the mother’s blood, look a week. These free beta-HCG and Papp-a. Free beta-HCG value has increased in infants with Down’s syndrome Papp-a Is determined as a lower value. Nuchal translucency, Papp-A and free beta-HCG levels, the detection rate calculated for Down syndrome when combined with close to 60%. Maternal age, nuchal translucency, Papp-A and free beta-HCG measurement scanning of these chromosomal abnormalities with detection rate up to 90% brings. Maternal age, gestational age, and nuchal translucency 11-14 of gestation by combining maternal serum markers. bilateral screening test between weeks shows us quite a long way.
Triple test; during the second 3 months in maternal blood free beta-HCG, AFP and estriol maternal age values of the proteins that is created with a combination of a diagnostic test is performed.
Amniocentesis; Fetal anomalies screening tests for risk is 1/270, in specific proportions, which gives this risk limit value, accordingly, the anomaly in the triple test or amniocentesis in pregnant women over the age of 35 the risk is greater than 1/270 of the structure of the chromosomes of the unborn baby puts another 100%. Under sterile conditions in the womb, where the baby was found approximately 20cc of amniotic fluid taken with a needle from the environment enetek is subject to review. In good hands the complication rate is quite low (2% to 0.2%) in this test which is the baby’s head on Down syndrome, including several anomalies are detected, but the decision on termination or continuation of pregnancy always belongs to the family, we just reveal pathologies that might yukumluyuz and to offer alternatives. The most important complication after amniocentesis that can be found that may affect the mother and the baby table and koryoamniyonit opening and the membrane is low. Any bleeding with a blood disorder in pregnant women during amniocentesis in case of the transaction post-conflict should be made to the PIN.
Chorionic villus sampling (CVS); Usually 10-13. the week between is performed. Can be performed through the cervix or the snow from the road. The placenta, which formed a kind from the piece. CVC complications is similar to amniocentesis. Advantage very early to recognize a fetus with malformations.
Cordocentesis; Often be suspicious of CVC or the results of amniocentesis, or in cases that should be taken for quick results is used to provide the blood cells of the fetus for genetic analysis. Fetal blood chromosome analysis usually results within 24 to 48 hours. If a blood sample is required fattah, metabolic, hematological tests, acid-base analysis, viral cultures and sent for immunological studies. Again, ultrasound-guided uterine by passing the blood from the veins of the baby to be taken technique. Cordocentesis amniocentesis is similar to many complications. Among other complications from the umbilical cord bleeding, or bleeding between the baby and a reduction in the heart rate of the baby is located. The baby is about the process of death by 1.4%. But the procedure may vary according to the baby’s condition and indications.
