Risk of miscarriage
in CVS in about 0.5 - 1%. Apart from a risk of miscarriage, there is a risk of infection and amniotic fluid
leakage. The resulting amniotic fluid leak can develop into a condition known as oligohydramnios
which is low amniotic fluid level. If the resulting oligohydramnios is not treated and the amniotic fluid continues to leak it can result in the baby developing hypoplastic lungs (underdeveloped lungs).
Additionally, there is also mild risk of Limb Reduction Defects associated with CVS, especially if the procedure is carried out in earlier terms (before 12th week of pregnancy
It is important after having CVS that the OB/GYN follow the patient closely to ensure the patient does not develop infection.
