title: Analysis of chromosomally normal spontaneous abortions after chorionic villus sampling.
abstract: Analysis of patients who spontaneously aborted chromosomally normal pregnancies following chorionic villus sampling (CVS) revealed an overall loss rate of 5.4% but a rate of only 3.2% if the procedure was performed between 9 and 12 menstrual weeks. There is preliminary evidence to suggest that a small but significant risk of infection is related to CVS.
