ABSTRACT

Etudier les facteurs pronostiques scannographiques de l'otospongiose en corrélant les résultats audiométriques post opératoires aux données scannographiques préopératoires. Méthodes: Nous avons mené une étude rétrospective, descriptive et analytique entre Janvier 2013 et Décembre 2018. Elle a inclus 50 patients soit 54 oreilles opérées pour otospongiose, explorés en préopératoire par une tomodensitométrie (TDM) des rochers et en postopératoire par des audiogrammes. Les critères de succès fonctionnel étaient un rinne résiduel postopératoire (RRPO) ≤10 dB et une réserve cochléaire (RC) ≤0. Résultats: La sensibilité de la TDM pour le diagnostic d'otospongiose était de 94% et le type II de la classification de Veillon était le plus fréquent (41%). La confrontation des données de la TDM préopératoire aux résultats audiométriques a permis d'identifier comme facteurs tomodensitométriques de bon pronostic audiométrique: les stades radiologiques localisés type I et II de Veillon et l'absence d'effraction endostée. L'absence d'atteinte de la fenêtre ronde ainsi que l'absence de variantes anatomiques étaient corrélées à un meilleur taux de fermeture du rinne en postopératoire. L'étude multivariée n'a pas retenu de facteurs scannographiques indépendants de succès fonctionnel. Conclusion: D'après notre étude, il s'avère que la tomodensitométrie des rochers préopératoire ne prédit pas le résultat audiométrique de la chirurgie de l'otospongiose. Néanmoins, elle reste indispensable pour la confirmation diagnostique, la classification de la maladie et la détection des anomalies associées.

ABSTRACT

Hepatobiliary surgery through laparoscopic approach is becoming a routine. Knowledge of extrahepatic arterial tree is essential for surgical and imaging procedures. Anatomical complexity is expected since the liver is developed by mergingof lobules with its separate blood supply. This makes a wide range of variations in the pattern of vascular arrangement and so reinforces the need for an accurate understanding of full spectrum of variations. This study aimed to investigate the variations in origin and distribution of extrahepatic arterial supply. Fifty volunteers (32 males and 18 females) aged 20­70 years were randomly recruited from the department of CT scan in Al Amal Hospital, Khartoum North, Sudan. The patients were already candidates for CT angiography with contrast for conditions other than hepatobiliary diseases. The reported data is related to those who accepted to participate in the study. Patients with history of hepatobiliary disease were excluded. 3D views of the scans were treated and the extrahepatic arterial tree was traced in a computer-based software. Key findings suggest that Michel's classification was considered the standard template for description ­ 76% of them showed Michel's type I classification. Types III and V constituted about 2%. About 4% of the cases were represented by types VI and IX. Other types of variations constituted about 12%. To conclude, although type I classification which describes the textbook pattern of hepatic artery distribution was significantly detected among the Sudanese population, other variants were to be considered since they are related to major arteries like aorta and superior mesenteric.

ABSTRACT

The diagnostic challenges in an 11 year old boy with a swollen forearm in a resource limited country; Nigeria; is discussed; with a brief review of literature of the causes of forearm swelling in a child and vascular malformations. This case is presented because of the rarity of arteriovenous malformation and the difficulty in making a diagnosis due to its low level of suspicion as a differential diagnosis. In this country where there is paucity of vascular surgeons; the challenges of management of arteriovenous malformations and the various imaging modalities are discussed
