Pränatale Diagnostik fetaler Neuralrohrdefekte

Neuralrohrdefekte zählen zu den frühesten und häufigsten strukturellen Fehlbildungsmanifestationen des Feten. Ein Neuralrohrverschluss kann dabei auf jeder Höhe der embryonalen Neuralplatte und in unterschiedlichem Ausmaß unterbleiben. Anenzephalie, Enzephalozele und Spina bifida sind die 3 Ausprägungen eines Neuralrohrdefektes. Jede dieser Formen zeigt in der Ultraschallbildgebung charakteristische Leitsymptome und weitere Hinweiszeichen.
