2% had an experience of Chorionic villus
sampling among which 20% abortions were reported.

C, Hofbauer cells are closely packed and confluent in the stroma of this CD163-stained tertiary chorionic villus
How to perform transabdominal chorionic villus
sampling: a practical guideline.
DISCUSSION: Chorionic villus
sampling has emerged as the only safe invasive prenatal diagnostic procedure in the first trimester.
Currently, prenatal diagnosis of Wilson disease is performed by analyzing fetal cells collected by either chorionic villus
sampling or amniocentesis.
August 8 by aspiration cytologic type "Chiba" for amniocentesis and chorionic villus
sampling, are asked to send technical details, IFU if available and / or any other documentation showing the indication of use of the needle.
This new method of risk assessment has resulted in a shift to first trimester diagnostic testing by way of chorionic villus
sampling (CVS) in the high-risk group of women identified by screening with nuchal translucency and serum biochemistry, and also far less diagnostic testing, which itself carries a risk of miscarriage.
However, Dr Al Hejari revealed many still chose to undergo a Chorionic Villus
Sampling (CVS) test at around 11 weeks and then get an abortion if a hereditary disease was detected, often travelling abroad for the procedure - including to Saudi Arabia, Iran and Egypt.
To contain the spread of this fatal disease, his foundation also creating awareness amongst people and advised those families where already a thalassemia patients exist to do Chorionic villus
sampling (CVS) test after three months of pregnancy and if the test was positive the doctors advised for abortion.
But it identifies fewer chromosomal abnormalities than combination screening or the more invasive chorionic villus
sampling and amniocentesis.
The only definitive test involves chorionic villus
sampling and amniocentesis but that carries a risk of miscarriage.
Existing invasive diagnostic tests -- Chorionic villus
sampling (CVS) and amniocentesis, which use samples from the developing placenta, are still only 75-90 per cent accurate with a risk of miscarriage," he said.
Other existing methods for detecting the condition - which causes physical and learning disabilities and raises the risk of heart disease - are amniocentesis, in which a needle is inserted into the womb to remove amniotic fluid, and chorionic villus
sampling, whereby a piece of placenta is taken for genetic testing.
