P20.10: Risk of fetal loss in pregnancies undergoing mid-trimester amniocentesis after inconclusive chorionic villus sampling

Fetal loss rates after mid-trimester amniocentesis

Objective: Amniocentesis is an invasive cytogenic test traditionally associated with a 1/200 procedure–related pregnancy loss rate. Recent studies have questioned the validity of the traditionally stated rate. The purpose of this study was to document the results of second-trimester genetic amniocentesis performed at our perinatalogy clinic. Study Design: A retrospective review of all the amnio...

Amniocentesis and Chorionic Villus Sampling

Fetal loss rate after chorionic villus sampling and amniocentesis: an 11-year national registry study.

OBJECTIVE To assess the fetal loss rate following amniocentesis and chorionic villus sampling (CVS). METHODS This was a national registry-based cohort study, including all singleton pregnant women who had an amniocentesis (n = 32 852) or CVS (n = 31 355) in Denmark between 1996 and 2006. Personal registration numbers of women having had an amniocentesis or a CVS were retrieved from the Danish...

Mid-trimester amniocentesis fetal loss rate.

OBJECTIVE To determine the postprocedure loss rate for mid-trimester genetic amniocentesis. OUTCOME Reduction of benign biopsy rates. BENEFITS To provide better advice for women about the risks and benefits of mid-trimester genetic amniocentesis, and to ensure that women are given sufficient information/counselling to make a decision about screening. SUMMARY STATEMENT The risk of postproc...
