Chorionic Villus Sampling and missing fingers, missing toes and hemangiomas?
Pregnancy counselors offer Chorionic Villus Sampling as a way to determine whether a fetus is likely to have Downs Syndrome. CVS is an alternative to amniocentesis. Some prefer CVS to Amnio because CVS can be performed earlier in the pregnancy, typically at 10 to 12 weeks compared to 15 to 18 weeks. Whether to undergo chorionic villus sampling is a sensitive decision that should be made only after full consideration of the risks and benefits. I became familiar with the procedure as an attorney representing children born with missing fingers and missing toes and hemangiomas, which, we believed were caused by CVS procedures that occurred in Portland, Oregon.
Sometimes, patients and doctors consider procedures too lightly. In the case of CVS and Amnio, some counselors just tell the women, "at your age, you should probably have chorionic villus sampling or amniocentesis." But that should be just the start of the conversation, not a box to check on a consent form. Here are some of the things that the counselors should walk you through.
What is the benefit?
You must determine what are YOUR risks that YOUR baby will have Downs Syndrome or some other genetic anomaly that the test will identify. More importantly, what would you if the test showed an anomaly? The only purpose for any medical test to obtain information that you will act upon. If there are no actions you can or would take based upon the results, then don't take the test. Counselors should review this with you, I believe. CVS became popular because it offered results in the first trimester, which meant an abortion could then occur in the first trimester, if so desired.
What are the risks?
Medical knowledge changes rapidly. Early studies indicated a correlation between CVS and "transverse limb anomalies," which often meant missing fingers, missing toes, or other shortening of the limbs. Some later studies downplay the risk and some argue that the early bad results were due, in part, from performing CVS before the 10th week. Personally, I've noted a correlation between the gestational development and the injury. So, it is not surprising to me that later studies tend to find the limb defects more limited. Now that more tests occur at the 11 or 12 weeks, compared to 9 or 10 weeks, it makes sense that the fetus was more developed and less susceptible to injury.
Hemangiomas, which look like port wine stains on the skin, is another condition researchers and others have noticed among children born following chorionic villus sampling.
Of course, your pregnancy counselor should discuss with you the above risks, and all other risks, before you decide whether to go forward with the procedure.
If (1) your Oregon pregnancy counselor did not thoroughly cover the risks and benefits, (2) you would have decided against CVS if she had discussed these issues, and (3) your child suffered because of the poor counseling, then you should contact me, an Oregon attorney who has helped children injured because of bad counseling regarding chorionic villus sampling.
