A New Stepwise Molecular Work-Up After Chorionic Villi Sampling in Women With an Early Pregnancy Loss [PDF]

Frontiers in Genetics, 2021
Objective: To explore the use of a new molecular work-up based on the stepwise use of Quantitative Fluorescence PCR (QF-PCR) extended to eight chromosomes and single nucleotide polymorphism array (SNP-array) in chorionic villi obtained by chorionic villi

To guide or not to guide: A randomized study on the use of needle guide for chorionic villus sampling training [PDF]

Acta Obstetricia et Gynecologica Scandinavica
Introduction Chorionic villus sampling (CVS) is an invasive prenatal diagnostic procedure used to detect fetal genetic anomalies. CVS is increasingly replaced by noninvasive prenatal testing (NIPT).

Chorionic Villi Sampling [PDF]

Journal of Medical Genetics, 1987
The cytogenetic findings were analysed in a series of 500 pregnancies in which chorionic villi sampling was performed. In all cases a direct method was used, karyotyping being successful in 481 cases (96.2%). The main indication for sampling was maternal age over 36 (412 cases; 82.4%).

Case report: Prenatal diagnosis of rare chromosome mosaicism: discordant results between chorionic villi and amniotic fluid samples

Frontiers in Genetics, 2023
Objective: We described a unique case of near-negative chromosome mosaicism in chorionic villi but complete monosomy X in amniotic fluid.Methods: Chorionic villus sampling and amniocentesis were performed separately in the first and second trimesters ...

Discordant structural chromosomal aberrations in chorionic villi and amniotic fluid leading to a formation of an isochromosome 21: a case report

Molecular Cytogenetics, 2021
Background Fetoplacental discrepancies occur in approximately 1–2% of analyzed prenatal cases. They are typically due to confined placental mosaicism, where an aberration is observed in the placental cells but not found in the fetal cells.

Case Report: How whole-genome sequencing-based cell-free DNA prenatal testing can help identify a marker mhromosome

Frontiers in Genetics, 2022
A supernumerary marker chromosome (SMC) is a structurally abnormal chromosome that cannot be characterized by conventional banding cytogenetics. Marker chromosomes are present in 0.075% of prenatal cases.

Examination and Sampling of Chorionic Villi for the Diagnosis of Beta-Thalassemia Major in the First Trimester of Pregnancy in Southwestern Iran [PDF]

Armaghane Danesh Bimonthly Journal, 2023
Background & aim: Beta thalassemia is one of the most common hereditary diseases in Iran. The birth of a child with thalassemia causes many social and economic problems for parents and the health care system.

Evidence for contamination as the origin for bacteria found in human placenta rather than a microbiota.

PLoS ONE, 2020
Until recently the in utero environment of pregnant women was considered sterile. Recent high-sensitivity molecular techniques and high-throughput sequencing lead to some evidence for a low-biomass microbiome associated with the healthy placenta.

Diagnostic Test On Modified Score Of Cesarean Section History In Placenta Accreta Index In Predicting Placenta Accreta Diagnosis In Rsup Dr M Djamil

Andalas Obstetrics and Gynecology Journal, 2021
Introduction : Placenta accreta is defined as abnormal implantation of placenta villi which invades myometrium without the presence of decidua bacalis resulting in placenta that is difficult to remove.

Pregnancy Outcome of Chorionic Villus Sampling on 260 Couples with Beta- Thalassemia Trait in North of Iran [PDF]

Acta Medica Iranica, 2010
"nChorionic villus sampling (CVS) is a new method and its true risk of fetal loss and complications is not still clearly determined. The objective of this study was to review the clinical pregnancy outcome of transabdominal CVS (TA-CVS) performed on
