OP01.24: Feasibility, accuracy and safety of late chorionic villus sampling: a report of 5,000 cases
There is extensive evidence that effective screening for major chromosomal abnormalities can be provided in the first trimester of pregnancy. Randomized studies have established that the risk of miscarriage from chorionic villus sampling in the first trimester is the same as for amniocentesis in the second trimester. Prospective studies have demonstrated that screening by a combination of fetal...
Patients with ataxia telangiectasia (AT) syndrome exhibit a high level of spontaneous chromosome aberrations, with hypersensitivity to gamma radiation and radiomimetic chemicals at the chromosomal and cellular level. Previously pregnancies at risk for AT have been screened solely by analysis of amniotic fluid samples. In this report we describe a cytogenetic approach to the prenatal diagnosis o...
