Évaluation de la pratique de l'amniocentèse sur le réseau sud-ouest francilien pendant l'année 2003

Our study has highlighted several practices of amniocentesis within the network. Overall, amniocentesis potentially induces 1.12% of fetal losses. Screening tests are currently used sequentially, which leads to an increase number of amniocentesis and to an increase number of losses of “a priori” healthy fetus. Only the use of a combined screening could lower the frequency of amniocentesis without decreasing the detection rate of chromosome abnormalities.
