Chorionic villi sampling: Women's attitudes

American Journal of Medical Genetics, 1985
AbstractTo determine the acceptability of chorionic villi sampling (CVS) to women eligible for prenatal diagnosis, we undertook a survey to identify aspects of this new procedure that made it more or less preferable than amniocentesis. All women ≥ 35 years scheduled for amniocentesis were asked to read some detailed descriptive material about ...

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.

Uncommon chromosomal mosaicism in chorionic villi

Prenatal Diagnosis, 1991
AbstractThree cases of unusual chromosomal mosaicism are reported for which the cytogenetic data show inconsistent findings between CVS and AC or fetal tissue, and which cannot be explained simply by non‐disjunction. For case 1, in CVS the karyotype was 46,XY, whereas lymphocytes and fibroblasts revealed 69,XXY.

Cell cycle studies in chorionic villi

Human Genetics, 1988
We have studied the cell cycle of cells obtained from chorionic villi in direct and culture preparations by incorporation of the thymidine analogue BrdU to produce late-labelling or sister chromatid differentiation patterns. We have, therefore, been able to estimate the duration of the cell cycle and, more specifically, the length of some of its phases.

Immunocytochemistry of human chorionic gonadotropin in human chorionic villi

American Journal of Obstetrics and Gynecology, 1987
The immunocytochemical localization of human chorionic gonadotropin was investigated in chorionic villi from the seventh to twelfth week of gestation. By the light microscopic peroxidase-antiperoxidase technique, positive reactions of human chorionic gonadotropin were found exclusively in the syncytiotrophoblast.

Discrepancies in cytogenetic findings in chorionic villi

The Journal of Maternal‐Fetal Medicine, 1997
We present a database and a review of published literature on discrepancies in chorionic villus (CV) diagnostic findings. The review includes 457 cases of discrepancies between CV findings (direct, culture, or both) and the fetus. One hundred and one cases reported normal by CV direct harvest included 30 with abnormal or mosaic abnormal fetal karyotype

Alkaline Phosphatase Expression in Human Chorionic Villi

Pathobiology, 1987
The physicochemical properties and electrophoretic mobility of different isoforms of alkaline phosphatase were studied in chorionic villi. Based on selective inactivation and inhibition studies (thermal stability, inactivation by urea, EDTA and L(+)ascorbic acid and <i>L</i>-amino acid inhibition), evidence was obtained for the existence of

Chromosomal Abnormalities in Ectopic Pregnancy Chorionic Villi

Journal of the Society for Gynecologic Investigation, 1998
To evaluate the incidence of chromosomal abnormalities in ectopic pregnancy chorionic villi.A prospective study of patients with the diagnosis of ectopic pregnancy was conducted, with chorionic villi obtained at the time of surgical therapy cultured and analyzed for karyotype.

Freezing of Chorionic Villi

1985
First trimester chorion biopsy is becoming more common in prenatal diagnosis. A simple method for storing chorionic villi in liquid nitrogen allows direct chromosomal preparation and the cultivation of chorionic villi cells to be performed at a later date.

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.
