Résumé
L’engagement est une notion mécanique essentielle dans le phénomène de la parturition et sa dépendance avec la possibilité d’un accouchement par les voies naturelles est certaine. L’approche clinique du diagnostic d’engagement est très subjective et soumise à des taux importants d’erreur par excès ou par défaut. L’échographie a déjà fait la preuve de son intérêt dans le diagnostic de variété de présentation et permet également de localiser des repères foetaux qui proposent d’évaluer ou d’extrapoler la hauteur de la présentation dans l’excavation pelvienne. Différentes techniques existent à ce jour.
Ce travail se propose de faire une analyse exhaustive de la littérature sur le sujet.
Même si des études complémentaires restent à faire, l’échographie transpérinéale avec mesure de la distance périnée-présentation apparaît extrêmement intéressante pour une utilisation large avant la pratique d’un accouchement assisté. Cette technique est simple, d’apprentissage aisé, ne nécessitant pas un matériel spécifique et est basée sur le même principe que la classification internationale du niveau de présentation dans l’excavation pelvienne (distance en cm par rapport à un repère maternel).
