摘要: This study evaluated the prenatal diagnosis of Turner syndrome by ultrasound examination in an unselected population from all over Europe. Data 19 congenital malformation registries 11 European countries were analyzed. was diagnosed 125 cases (7.2%) a total 1,738 chromosome abnormalities. Sixty-seven percent detected prenatally due to presence defects. The most frequent anomalies cystic hygroma (59.5%) and hydrops fetalis (19%). karyotype 45,X (81.6%) followed different types mosaicism (16.8%). Significant differences defects (P = 0.0003) observed between karyotypes cases. Prenatal counseling for should take into account expectation milder phenotype. In 78.6% anomalies, pregnancy terminated. detection high this population.
