Neural Tube Defects

Neuralrörsdefekter

Svensk definition

Medfödda missbildningar av det centrala nervsystemet och angränsande vävnadsstrukturer som beror på ofullständig tillslutning av neuralröret under graviditetens första trimester, vanligen under dagarna 19-29. Ektodermala och mesodermala missbildningar (främst av skallen och ryggkotorna) kan uppkomma som en följd av bristande tillslutning av neuralröret.

Engelsk definition

Congenital malformations of the central nervous system and adjacent structures related to defective neural tube closure during the first trimester of pregnancy generally occurring between days 18-29 of gestation. Ectodermal and mesodermal malformations (mainly involving the skull and vertebrae) may occur as a result of defects of neural tube closure. (From Joynt, Clinical Neurology, 1992, Ch55, pp31-41)
