In 44 pregnancies where chorionic villus sampling (CVS) had shown mosaicism, early amniocentesis using a filter technique was camed out with the purpose of clarifying the fetal karyotype and reducing the waiting time for a final karyotype. Since the filter technique increases the cell yield of the a

## Abstract Here we review a group of 82 patients who underwent both chorionic villus sampling (CVS) and amniocentesis in the same pregnancy during the period May 1984โMay 1988. A fetal loss rate of 2.5% is documented. This is not essentially different from the sum of fetal loss rates following eac
500 women with multiple pregnancies underwent amniocentesis or chorionic villus (CV) sampling at our department between January 1988 and July 1997. The aim of this retrospective study was to evaluate the laboratory aspects and the consequences of discordant results in these pregnancies in relation t
Up to now, no data are available comparing amniocentesis and chorionic villus sampling (CVS) using biopsy forceps. A series of 1313 consecutive women referred to our unit before 12 weeks of pregnancy for fetal cytogenetic analysis because of advanced maternal age, were randomized into CVS with the u
548 cell cultures and karyotypes obtained by early amniocentesis with filtration technique (EAF) at a mean gestational age of 12Y weeks were compared with 555 obtained by transabdominal chorionic villus sampling (CVS) at a mean gestational age of 11 weeks. The number of abnormal karyotypes, culture
