Other Potential Risks of Chorionic Villus Sampling
Chorionic villus sampling (CVS) is generally considered a safe procedure. However, like any medical intervention, there are potential risks that should be taken into consideration.
One of the rare risks associated with CVS is the possibility of miscarriage. While some sources previously suggested that the risk could be as high as two percent, recent studies have found that the risk of miscarriage directly resulting from CVS is as low as 0.22 percent. It is important to note that the risk may vary depending on individual circumstances and the expertise of the healthcare provider performing the procedure.
Older studies have also indicated that CVS could potentially lead to defects in the baby’s fingers and toes. However, modern research suggests that this is only a concern if the procedure is performed before the tenth week of pregnancy. Therefore, it is crucial for healthcare providers to carefully assess the gestational age before conducting CVS to minimize this risk.
In addition, although uncommon, there have been reports of women developing uterine infections after undergoing CVS. This highlights the importance of proper sterilization techniques and post-procedure care to reduce the likelihood of such infections.
It is essential for expectant mothers considering CVS to thoroughly discuss the potential risks and benefits with their healthcare provider to make an informed decision.
The Process of the Actual Test
Prior to undergoing the test, patients are provided with detailed information about the procedure and any potential risks by their doctor. In most cases, patients are required to sign a consent form. To ensure better accessibility, physicians may request certain women to have a full bladder before the test, especially if the uterus and placenta’s location are a concern. The test commences with the patient lying down on an examination table, positioning their hands behind their head. An ultrasound is conducted by a technician to initiate the procedure. Subsequently, depending on the location of the placenta, the doctor will proceed with the test either by entering through the cervix or through the abdominal wall.
