[Recent advances in prenatal diagnostics].
During the last years, technical improvements have increased the possibilities in prenatal ultrasound. During the eighties and nineties, fetal malformations were increasingly detected and specified. Since a few years, the measurement of the fetal nuchal translucency between 11 and 14 weeks of gestation has been implemented to calculate the individual risk, in combination with most recent biochemical markers. Today, the sonographic measurement of the nuchal translucency is regarded as a valuable screening tool for chromosomal anomalies in prenatal medicine. Beside standardized examinations, a profound information and counseling of the pregnant women should be emphasized. With the improvement of the specific maternal risk calculation, using the sonographic measurement of the nuchal translucency, the biochemical markers and the maternal age, unnecessary invasive examinations may be prevented and their overall number can significantly be reduced. The same trend is seen in the whole field of prenatal medicine, illustrated by the detection of the fetal rhesus D status from the maternal blood and the use of Doppler ultrasound in the management of fetal anemia.
