, Dysraphisme spinal : Corrélation pré et post-natale 78% des cas avec une marge d'erreur d'une vertèbre, et 96% des cas avec une marge d'erreur de deux vertèbres, contre respectivement 26%, 66% et 80% pour les échographistes non experts. L'étude montrait également que la performance des opérateurs pour situer le niveau lésionnel augmentait au fur et à mesure du déroulement de l'étude, que ce soit pour les experts ou pour les non-experts (22)

, publiée en 2009 et portant sur 41 foetus, retrouvait une corrélation entre les niveaux lésionnels échographiques et post-nataux dans 50% des cas entre, 1997.

É. Dans-notre, des anomalies associées étaient présentes chez 32,7% des foetus à l'examen post-natal. Ce résultat est plus élevé que celui retrouvé dans la littérature, qui est de l'ordre de 15 à 20% (27)

, Le taux de détection échographique des anomalies associées était de 58,8%. Ce résultat est inférieur à celui retrouvé dans la littérature, AFTN hautes situées, avec un niveau lésionnel supérieur au-dessus de L3, qui sont plus fréquemment associées à d'autres malformations

, De nouvelles technologies telles que l'IRM foetale et l'échographie 3D ont montré un certain intérêt dans le diagnostic, l'évaluation pronostique et la prise en charge des AFTN

L. 'étude-rétrospective-d'-appasamy, comparait les performances de l'échographie à celles de l'IRM foetale dans le cadre des dysraphismes spinaux, le niveau lésionnel échographique était corrélé à celui retrouvé en post-natal dans 8 cas sur 12, 2006.
