ReviewNonabortal pregnancy complications of chorionic villous sampling.
First trimester screening for genetic diseases has become the predominant tool for selecting higher risk women in developed countries. As a consequence, chorionic villous sampling (CVS) is considered the most effective method for early diagnosis. The purpose of this review is to report recent updates related to CVS complications. ⋯ Currently CVS is the gold standard method of first trimester prenatal diagnosis. Because it will likely be in higher demand in the next years, knowledge of the associated complications and their frequency is worth noting for both physicians and patients. Recent data have clarified some controversies and speculations but the magnitude of the association between CVS and fetal and obstetrical complications is still unclear.
