Хромосомный микроматричный анализ абортивного материала

Study objective is to assess the prevalence and pattern of chromosomal abnormalities (CAs) in products of conception (POC) for the period from 2015 to 2019. Materials and Methods: 2201 samples of POC were studied by the chromosomal microarray analysis. Study Results: CAs were detected in 49.57% of cases, of which aneuploidy, including several chromosomal and mosaic forms, were detected in 79.65%, triploidy - 10.72%, other CAs with possible clinical significance - 8.62%, tetraploidy - 1.01%. Conclusion: chromosomal microarray analysis can be recommended as a routine method for searching of unbalanced CAs in POC.
