Vaginosonographic guided chorionic villi needle biopsy (transvaginal chorionic villi sampling)

European Journal of Obstetrics & Gynecology and Reproductive Biology, 1986
Abstract A new obstetric approach to chorionic villi sampling in the first trimester using a transvaginal technique is described.

Intravascular Hematopoiesis in Chorionic Villi

American Journal of Clinical Pathology, 1983
Mitotic figures can be found in the immature blood cells in the fetal vessels of placental tissue in abortion specimens. Intravascular mitoses were noted only in the absence of degenerative changes and during the first trimester of gestation. This finding suggests that the vascular component is a normal site of hematopoiesis during this stage of ...

Hexokinase in human chorionic villi

Early Human Development, 1985
The level, intracellular distribution, and isozymic pattern of hexokinase (EC 2.7.1.1) were determined on human chorionic villi obtained by trophoblast biopsy in the first trimester of pregnancy. About 50% of total hexokinase activity was found to be particle-bound and 96% of this in the overt form (i.e.

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
