How CVS is done:
In CVS, doctors remove a small portion of placenta tissue from the uterus. This sample then sent to the laboratory for further testing. It involves two steps:
- A thin tube is inserted into the vagina to get placenta tissue. The doctor uses ultrasound images for guiding the catheter to the spot.
- In another way, a needle is inserted through the abdomen and then this needle takes placenta tissue from the uterus. As the same as the previous step, ultrasound is used to guide the needle.
