A Modified Portex Cannula for Chorionic Villi Sampling
1985Chorionic villi sampling (CVS) has several advantages which have been widely dis-cussed in the literature. Yet, one problem of this method is that we do not know exactly the procedure’s risk. It is very plausible that the more manipulation is needed to obtain a sufficient amount of chorionic villi for analysis, the higher the risk of an abortion will ...

[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 ...

Improved Echogenicity of the Catheter for Chorionic Villi Sampling
1985In the short time since the first successful direct chromosome analyses of chorionic villous material obtained at 8–11 weeks of pregnancy were reported from Italy (Si-moni et al. 1983), this method of first trimester diagnosis has attracted increasing interest in many different countries (Holzgreve et al. 1984). Developed at University College Hospital

[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 ...

[Chorionic villi sampling: experience of the initial 500 samples].
Revue medicale de Bruxelles, 1990We report our experience in first trimester antenatal diagnosis since 1984. Transcervical chorionic villus sampling (CVS) was performed in 498 pregnancies. The rate of abnormal pregnancies was 6%, the rate of chromosomal abnormalities (trisomy) in the indication group "maternal age" was 2%.
