Elevated nuchal translucency, is it time to discuss the cut off?

Fetuses with NT between 95th and 99th percentile have an increased risk of pregnancy and postnatal adverse outcomes. According to our data it is reasonable to consider a lower cut of NT (NT > 95th percentile) for offering further investigations such as detailed ultrasound scan, fetal echocardiography and counseling where the option of performing fetal karyotype and CGH array should be discussed.
