Chorionic Villi Sampling

1999
Since the mid 80s chorionic villi sampling (CVS) has become an important and powerful procedure in prenatal diagnosis. In this chapter, the abbreviation CVS is used in the common, broader sense including also the analysis of the extracted tissue.

Chorion Villi Sampling (CVS)

1994
Die Technik der Chorionzottenbiopsie (CVS) wurde in der VR China und in der Sowjetunion entwickelt (218). Das Konzept hierzu stammt schon aus dem Jahre 1968 (307, 638). Unter Verwendung von Aspirationskathetern oder — kanulen sowie Biopsiezangen last sich im I. Trimester zwischen der 7. und 12.

Identification of trophoblast in chorionic villi biopsy samples

Human Genetics, 1986
We have investigated a test for rapid discrimination between foetal and maternal origin of chorionic villi biopsy samples. A monoclonal antibody named H315 reacting against a specific antigen present on the surface of foetal trophoblastic cells, plus a double-colour staining technique (FITC + PI), have been used for the identification of foetal cells ...

Chorionic villi sampling: Laboratory experience with 4,000 consecutive cases

American Journal of Medical Genetics, 1994
AbstractExperience with 4,000 consecutive CVS cases shows that 1) the combination of both the direct and culture methods greatly reduces false diagnoses and maternal cell contamination; 2) the time interval between the sampling procedure and processing of villus specimens influences the quality of direct preparations; 3) maternal cell contamination ...

Prenatal diagnosis of genetic disease by chorionic villi sampling

The Indian Journal of Pediatrics, 1986
Chorionic villi sampling at week 9–11 of gestation is increasingly applied as a new method in prenatal diagnosis of genetic disorders. Cytogenetical, biochemical or recombinant DNA methods have been used successfully in more than 6000 pregnancies at risk.

Fetal mortality at the time of chorionic villi sampling

Human Genetics, 1984
To estimate the background fetal loss rates among women who might be candidates for chorionic villi sampling (CVS) for prenatal diagnosis, we examined the frequency of spontaneous abortion and of non-viable fetuses in two groups of women thought to be pregnant at 8-12 weeks' gestation.

First trimester chorionic villi sampling and direct chromosome preparations

Clinical Genetics, 1986
Chorionic villi sampling was performed on 52 patients prior to elective termination of their pregnancies. Villi were obtained in 42, and direct chromosome preparations were successful in 41 of them. The use of a mixture of 0.075 M potassium chloride and 1% sodium citrate in the ratio of 2:1 for hypotonic treatment and 40% acetic acid for cell dispersal
