Chorionic Villus Sampling (CVS)
Chorionic Villus Sampling (CVS)
Sampling from the placenta is performed for prenatal diagnosis. This sample is taken from the placenta, which shares genetic information with the fetus. By analyzing it, the detection of genetic disorders becomes possible.
Fetal Placenta
In the past, surgery was the only treatment option for hemangiomas, which was often not feasible in most cases. Today, with the use of minimally invasive endovascular treatments, it is possible to block the blood vessels supplying the hemangioma. As a result, the hemangioma becomes inactive, transforms into non-viable tissue, and eventually shrinks significantly.
Advantages of Embolization
This procedure is performed without anesthesia and has significantly fewer complications compared to surgery.
The patient’s return to normal daily life occurs in the shortest possible time.
This procedure involves minimal bleeding compared to surgery.
The recurrence rate is very low.
Method of Performing Fetal Placental Sampling
Sampling from the fetal placenta at this center is performed through the abdominal skin. First, the fetal heartbeat is assessed using ultrasound, followed by determining the position and thickness of the placenta. Under ultrasound guidance, a specialized sampling needle is inserted into the placenta, and the sample is collected.
The sampling procedure is performed without general anesthesia and solely with local anesthesia. The sensation of local anesthesia is similar to that of a muscular injection and is easily tolerable.
Intervention Clinics
The interventional clinics at pardis noor comprehensive imaging centers utilize advanced equipment and a specialized team to provide precise and highly safe minimally invasive medical treatments.
Sampling does not cause harm to the fetus.
Sampling from the placenta is performed by a skilled and experienced specialist. Since the needle is inserted solely into the placenta, it will never cause direct harm to the fetus.
Following chorionic villus sampling (CVS), there is a risk of miscarriage, which varies between 2% and 4% in different centers worldwide. However, based on the evaluation of patients at this center, the miscarriage rate has been less than 2%, which is lower compared to international centers.
Post-Sampling Complications
Spotting, bleeding, or discharge may occur following the sampling procedure. These symptoms usually resolve on their own and do not require any specific medication.
In individuals with no history of miscarriage or bleeding, 24 hours of rest at home is required after sampling. However, those with a history of miscarriage or bleeding require extended rest.
Number of sampling sessions
In most cases, an adequate sample of the placenta is obtained in a single session. However, in some instances, due to insufficient placental tissue, the presence of maternal tissue in the sample, or questionable test results, a repeat sampling may be required.
Necessary Preparations for Sampling
Removing unwanted hair from the uterine area
Carrying a laboratory referral letter.
The presence of a companion is required for administrative procedures.
Fasting and Medication Discontinuation: It is recommended to have a light breakfast on the morning of the sample collection. If you are taking any specific medication prescribed by your physician, continue taking your medication as usual on the day of the sample collection. There is no need to discontinue your medication.

Frequently Asked Questions
What is the most appropriate gestational age for sampling the placenta?
The most appropriate time for sampling the fetal placenta is between the 10th and 12th weeks of pregnancy. Sampling is not recommended before the 10th week of gestation, as it increases the risk of miscarriage.
