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...

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.

Mid-trimester genetic amniocentesis in twin pregnancy and the risk of fetal loss.

OBJECTIVE To assess the rate of fetal losses in twin pregnancies undergoing genetic mid-trimester amniocentesis. METHODS In the first part of this investigation, a retrospective cohort study compared a group of women . 32 years old with twin pregnancies who underwent amniocentesis with a similar group unexposed to amniocentesis. Data were compiled from January 1990 to March 2004 for patients ...

Pregnancy loss rates after midtrimester amniocentesis.

OBJECTIVE The purpose of this study was to quantify the contemporary procedure-related loss rate after midtrimester amniocentesis using a database generated from patients who were recruited to the First And Second Trimester Evaluation of Risk for Aneuploidy trial. METHODS A total of 35,003 unselected patients from the general population with viable singleton pregnancies were enrolled in the F...
