The presence of dorsonuchal edema is a sonographic soft marker that indicates a chromosomal peculiarity and / or an organic malformation in the child.

• Down syndrome (trisomy 21)
• Patau syndrome (trisomy 13)
• Edwards syndrome (trisomy 18)
• Turner Syndrome (Monosomy X)
• Triploidy

The dorsonuchal edema is listed in the maternity record under the heading "Ultrasound documentation". A possible presence will be checked in the course of maternity care in the period between the 9th and 12th week of pregnancy .
