In prenatal diagnosis, dorsonuchal edema is a pronounced accumulation of fluid that occurs on large parts of the back (= dorsal ) as well as in the back of the head and neck (= nuchal ) of the unborn child. In ultrasound a pronounced is edema visible through the neck and back skin of the child is clearly distinct from the body. It differs from a neck transparency by a "broadening" of more than 3 mm.
The presence of dorsonuchal edema is a sonographic soft marker that indicates a chromosomal peculiarity and / or an organic malformation in the child.
It often occurs in children with:
- general diseases or malformations in the area of the cardiovascular or lymphovascular system (e.g. heart defects )
- 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 .
