[Experience with chorionic villi sampling].
Orvosi hetilap, 1991The 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.

The role of transvaginal sonography in chorionic villi sampling
Journal of Clinical Ultrasound, 1990AbstractVaginosonography 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 ...

Investigations of chorionic villi after chorionic villus sampling (CVS)
Human Genetics, 1989This 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.

[Chorionic villi sampling. Amniocentesis. Cordocentesis].
Revue francaise de gynecologie et d'obstetrique, 1990For early antenatal diagnosis, chorionic villus sampling (CVS) represents a valid alternative to early amniocentesis. It gives rapid results with minimal increase in risks (miscarriage about 1.5 p. cent). The indications of CVS are therefore likely to broaden. For late antenatal diagnosis, linked to an echographic or clinical anomaly, sampling of fetal

[Chorionic villi sampling and prenatal diagnosis].
Revue francaise de gynecologie et d'obstetrique, 1992The authors report their experience of 790 villous specimens taken either early (for 430 cases) or late (360 cases) between 10 and 37 weeks of amenorrhea (WA) using a transabdominal syringe. In the early choriocentesis cases, they conclude that use of the transabdominal route after 12.5 WA, regardless of the position of the chorion, makes it possible ...

[Sampling, culturing and karyotyping of chorionic villi].
Journal de gynecologie, obstetrique et biologie de la reproduction, 1984The authors report on 69 samples of chorionic villi taken from patients who were undergoing therapeutic termination of pregnancy. These samples were taken using small forceps which were guided by ultrasound. The reliability and the chances of culturing these villi in order to work out the caryotype of the fetus and to study the enzymes is discussed.

[Fetal chromosome abnormalities diagnosed by chorionic villi sampling].
Orvosi hetilap, 1993Chorionic villus sampling was performed for chromosome analysis in 387 cases during a 4-year-period. In 115 cases transcervical while in 272 cases transabdominal sampling was carried out. Chromosomal abnormalities were found in 25 cases (6.4%). Autosomal trisomies occurred in 17 cases, structural anomalies in 2 cases and sex chromosomal aberrations in ...

[Chorionic villi sampling. Results with the first 500 samples].
Journal de gynecologie, obstetrique et biologie de la reproduction, 1989531 chorionic villi forceps biopsies were carried out, to look for genetic diseases. Sampling was impossible in 24 cases (4.5%). The following indications were chosen: maternal age over 38 years: 361 cases; parental chromosome abnormality: 28 cases; previous history of chromosome abnormality: 21 cases; X-linked disease: 77 cases; metabolic disease: 32 ...
