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.

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.

The role of transvaginal sonography in chorionic villi sampling

Journal of Clinical Ultrasound, 1990
AbstractVaginosonography has the potential of improving not only accurate diagnosis preceeding chorionic villus sampling but also the sampling procedure itself. The vaginosonographic diagnostic landmarks of early pregnancies are the contact area between the amnion and the chorion, the insertion of the umbilical cord, the yolk sac and the decidua ...

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 ...

[Experience with chorionic villi sampling].

Orvosi hetilap, 1991
The authors discuss their experiences from 412 chorion villus samplings, (CVS), which they have done under four and a half years since 1985. They used eight types of instruments in performing their examinations and each instrument proved to be satisfactory in the gaining of chorion villus samples, suitable for further tests.

Investigations of chorionic villi after chorionic villus sampling (CVS)

Human Genetics, 1989
This report documents the first 262 cases of chorionic villus sampling (CVS) performed in parallel with cytogenetic and morphological investigations. Histomorphological examination of these CVS specimens gave suitable results in about 96% (251 cases). Of the latter, 201 samples (80.1%) exhibited villi and 176 (70.1%), maternal tissue.
