Abstract
|
|
|
Purpose: To present our experiences in pseudomosaicism or maternal celi contamination in genetic mid-trimester amniocentesis confirmed through percuraneous umbilical blood sampling.
Methods: From 1992 to 1997, repeated cytogenetic evaluation with fetal cord blood was carried out in 14 cases showing mosaic patterns.
Results: We confirmed pseudomosaicsm in 12 cases (85.7%) by repeated cytohenetic evaluation, and also maternal cell contamination in 2 cases.
Conclusion: Repeated cytohenetic evaluation via percutaneous umbilical blood sampling was a rapid and useful method fof the confirmation of mosaicism resulted from genetic mid-trimester amnicentesis.
