What potential risks or complications are associated with chorionic villus sampling and how do these risks compare to other prenatal diagnostic tests in terms of accuracy and safety?
1. Chorionic villus sampling (CVS) can lead to miscarriage, infection, or inaccurate results. It’s more invasive than ultrasound but can detect abnormalities earlier than amniocentesis.
2. CVS risks include a 0.5-1% chance of miscarriage and rare cases of limb defects. It offers earlier results than amniocentesis, but with slightly higher risk.
3. Potential complications of CVS include miscarriage, infection, and Rh sensitization. It is more accurate than ultrasound for genetic disorders but carries a higher risk than non-invasive tests.
1. Chorionic villus sampling (CVS) risks include miscarriage (0.5-1%), infection, and limb defects. Compared to amniocentesis, CVS is done earlier but has a slightly higher miscarriage risk.
2. CVS can cause miscarriage, infection, or rare birth defects. Its miscarriage rate is higher than non-invasive tests like NIPT, but it provides earlier results than amniocentesis.
3. Potential complications of CVS include miscarriage (<1%), rh sensitization, and limb deformities. It's riskier than NIPT but similar to amniocentesis in terms of early diagnostic accuracy.
