Question 1

should i have cvs or amniocentesis?

Accepted Answer

Maybe: CVS and amniocentesis are tests that some patients will choose to have to help get a diagnosis. They allow testing of the baby's genes and help diagnosis genetic defects. These tests are not done routinely on everyone but rather on those who are at high risk for genetic diseases. Age > 35 or an abnormal blood test for Down syndrome would be examples of those who might consider this.

Question 2

why is it important to do cvs or amniocentesis?

Accepted Answer

Personal decision: Both tests are 100% accurate in determining whether or not the baby has chromosomal problems like down's syndrome.  Women over 40 have a 1 in 20 risk of this.  Some people would terminate the pregnancy if they knew the baby had a chromosomal problem.  The cvs gives you info earlier than the amnio but has a higher miscarriage rate.

Question 3

is a cvs a higher risk procedure than amniocentesis?

Accepted Answer

No: Amniocentesis is usually offered between 15-20 weeks, with a pregnancy loss rate of about 1 in 300-500.  Chorionic villus sampling (cvs) is offered after 9 weeks.  The pregnancy loss rate appears to be about the same as amniocentesis.  There are additional fetal risks if it is performed before 7 weeks.  The benefit of cvs is earlier detection, which allows for safer termination, if desired.

Question 4

how do i decide whether to have amniocentesis or cvs?

Accepted Answer

Personal decision: Your decision should be based on your age-related risk for chromosomal problems (higher the older you are), how important it is to you to get early information, and how much risk you are willing to take in finding out the information.  Generally cvs will give you information one month before an amnio but has a risk of miscarriage triple that of an amnio.

Question 5

are there risks involved in getting an amniocentesis or cvs?

Accepted Answer

Yes: Both have a risk of miscarriage.  The risk is about 4 times higher with a cvs than an amniocentesis.

Question 6

is it dangerous to have cvs or amniocentesis?

Accepted Answer

No: It is uncommon to have complications from amniocentesis or cvs.  There is a small increased risk for miscarriage from these procedures.  The physician who is performing the procedure can give their rates, usually less than 1% for an amniocentesis and 1% for cvs.

The acog website has a nice handout on these procedures.

Question 7

which of the two tests are better? or are recommended ? amniocentesis or cvs (chorionic villus sampling )? no past history of any health problems.

Accepted Answer

It depends.: CVS is generally thought to have a slightly higher miscarriage rate than amniocentesis, but this may not be the case everywhere. For mor e information check this link:

Question 8

chorionic villus sampling vs amniocentesis risk?

Accepted Answer

Risk: Risk of pregnancy loss with cvs and amniocentesis are equivalent. That's been shown by four different studies. In experienced hands the loss rate is something like 1 in 1600.

Question 9

someone here please explain the difference between chorionic villus sampling and amniocentesis?

Accepted Answer

CVS and Amnio: A cvs is done earlier in pregnancy and involves getting tissue from the placenta. An amniocentesis is done later in pregnancy. It involves getting amniotic fluid from the gestational sac. Chromosomal abnormalities can be found by both techniques. An amniocentesis can also check for neural tube defects. A genetic disease, such as cystic fibrosis can be diagnosed by either technique.

Question 10

how is cvs diagnosed?

Accepted Answer

CVS is Rare: Cyclical vomiting syndrome (cvs) is a diagnosis of exclusion. It is a rare problem. It has a very typical pattern of severe vomiting which lasts for less than 48 hours. In between episodes, people are totally fine. Attacks occur every few weeks or months. Acid reflux, gastroparesis, gallbladder and pancreas disease need to be excluded. Avoid marijuana - it has recently been implicated as a cause.
