Embolie Pulmonaire Aigue : Etude Epidemiologique Et Tomodensitometrique
Mots-clés :
Embolie pulmonaire aiguë, scanner multicoupeRésumé
Prérequis: l’embolie pulmonaire aiguë est une pathologie fréquente et grave nécessitant un diagnostic positif de certitude rapide.
Buts : Evaluer la prévalence de l’embolie pulmonaire aiguë et calculer la sensibilité et la spécificité du scanner multicoupe pour le diagnostic positif de l’embolie pulmonaire aiguë dans un hôpital spécialisé en pathologies cardio-thoraciques.
Méthodes : il s’agit d’une étude prospective, menée à l’hôpital Abderrahmène Mami de l’Ariana, ayant inclus 200 patients consécutifs suspects d’embolie pulmonaire aiguë et explorés par un angioscanner pulmonaire multicoupe (16 coupes).
Résultats : La prévalence de l’embolie pulmonaire aiguë a été calculée à 37,5%. Le scanner multicoupe a permis de réaliser un diagnostic alternatif chez 46 patients (40%). La sensibilité et la spécificité du scanner multicoupe ont été calculées respectivement à 89.6% et 100%,
Conclusion : La prévalence de l’embolie pulmonaire aiguë, dans un hôpital spécialisé en pathologies cardio-thoraciques, est supérieure à celle retrouvée dans les hôpitaux généraux. La sensibilité et la spécificité élevées du scanner multicoupe en font l’examen de référence pour le diagnostic de l’embolie pulmonaire aiguë.
