Chorionic

1. Who needs to be done chorionic sampling inspection? Not all pregnant women need to do chorionic sampling inspection, the following can recommend this method. ● older than 35-year-old pregnant women, would like to know as soon as possible whether there is a fetal chromosomal abnormalities; ● Health and the deformed babies of pregnant women; ● family history of genetic disease in pregnant women. 2. How do chorionic sampling inspection? Choriocarcinoma is a sampling checks taken from the pregnant uterus some of the placental tissue examination. First ultrasound examination determined gestational age and fetal placental location, and then determine the location of the placenta, select sampling method. One is through the vagina, cervix insert a thin flexible catheter is to the development of the placenta (the cervical approach), and the other is a needle inserted through the abdomen to the placenta (the abdominal method), in a small number of villi for analysis. A method previously used. 3. Chorionic sampling inspection best time to do what? Chorionic sampling inspection best time for pregnancy 9 to 12 weeks. In the early stages of pregnancy can check sampling inspection is chorionic advantages. 4. When pregnant women do not chorionic sampling inspection? ● period from the end of the day when, more than 12 weeks gestational age of any pregnant women; ● exist when vaginal infection; ● abnormal uterine shape, such as uterine fibroids or with dual-angle uterus; ● When severe vaginal bleeding. 5. Chorionic sampling inspection of pregnant women affected? Chorionic sampling inspection is a traumatic examination. If the operation correctly, chorionic sampling inspection is safe. About 0.6% to 2.9% of pregnant women in the chorionic sampling, possible uterine cramps, vaginal bleeding a little. These symptoms lasted a short time, without adverse effects on pregnancy. Others can be dangerous: fetal membranes rupture, and did not get the analysis of placental tissue. Rh negative pregnant women to Rh globulin injections to prevent Rh blood group incompatibility problems. 6. Chorionic sampling inspection, will affect fetal development? Not. Because clinical villus cells extracted from embryos outer beam. Beam, a matrix, with the pregnancy and chorionic villus cells in the growth of progressive degradation, so early diagnosis of fetal development from villi have no impact. Recently there have been reported in the literature but, chorionic sampling inspection and fetal deformity shortened limbs in a certain relationship. 7. Chorionic sampling up with the amniotic puncture the advantages? Early in a prenatal diagnosis of fetal genetic and biochemical aspects of the anomaly is chorionic sampling inspection of the main advantages. Chorionic comparable sampling inspection checks amniotic puncture early 4-6 weeks. Some women choose to check the reasons for this is they want to know the results as soon as possible in order to make the decision of the pregnancy. 8. Chorionic inadequacies of the sampling inspection? Chorionic sampling inspection can not detect certain congenital malformations such as neural tube defects, congenital heart disease, as well as fetal lung maturity. A very small number of cases, the results of human chorionic sampling inspection is not true fetal chromosome map, it checks to the placenta chromosome abnormality, and did not reflect their own fetus. These cases of the unusual circumstances, we need to do further checks. 9. Do chorionic sampling inspection, what are the uncomfortable feeling? Cervical used by the sampling method, and often have the feeling uterine cramps, and that's it. The whole operation without anesthesia. 10. Villus sampling can be used for any inspection? ● fetal chromosome analysis: In determining the normal chromosome sequencing and the sex of the foetus, and Down syndrome chromosome disorder can be diagnosed. ● DNA research: only done when necessary. Through DNA analysis to diagnose certain diseases, such as cystic fibrosis and muscular dystrophy disease. Villus sampling before genetic counseling can be related to family history information, in this way we can on the prenatal diagnosis of some of the issues for discussion. 11. Chorionic sampling inspection and analysis of fetal chromosomal accuracy rate? Chorionic sampling inspection accuracy rate is relatively high, up to 99%. But very few cases, sometimes also called for further do amniotic puncture.
