Is amniocentesis related to the risk of fetal limb defects?

Amniocentesis is a procedure used in prenatal diagnosis to obtain amniotic fluid, which contains fetal cells and various substances, for genetic testing and other assessments. The association between amniocentesis and the risk of fetal limb defects is significant due to the potential for procedural complications, such as injury to the fetus or disruptions in the developing limb structures.

Research has indicated that while the overall risk is low, there is a documented increase in the incidence of limb deformities following amniocentesis, particularly in certain contexts or after multiple procedures. This has prompted further studies to assess the relationship more thoroughly, ultimately leading to the acceptance of this association in medical literature.

The acknowledgment of a connection underscores the importance of weighing the benefits and risks of amniocentesis when considering diagnosis options in pregnancy. Healthcare providers must provide information to expectant parents about the potential risks—including limb defects—while discussing testing options.
