RESUMO

Les artères digestives essentiellement le tronc cœliaque et l'artère mésentérique supérieure présentent plusieurs variantes anatomiques notamment au niveau de leur origine. L'objectif de cette étude était d'illustrer l'anatomie normale ainsi que les variantes anatomiques des artères digestives vues au scanner. Nous avons réalisé une étude transversale portant sur les scanners avec coupes abdominales sans et avec injection de produit de contraste iodé au temps artériel. Le tronc cœliaque et ses branches, l'artère mésentérique supérieure et l'artère mésentérique inférieure ont été étudiés. Nous avons collecté 155 patients. Plusieurs variantes anatomiques fréquentes et multiples ont été retrouvées, dont l'absence de tronc cœliaque (3 cas), le tronc hépato-splénique (12 cas), le tronc hépato-gastrique (2 cas), le tronc gastro-splénique (5 cas) et le tronc coeliacomésentérique (1 cas). Pour l'artère hépatique, il existait les types I (121 cas), II (13 cas), IV (1 cas), V (3 cas) et IX (3 cas) selon la classification de Michels, ainsi que d'autres variantes non classifiées (14 cas). Nous avons trouvé également une artère mésentérique moyenne reliant l'artère mésentérique supérieure de l'artère mésentérique inférieure. Cela justifie l'importance et la nécessité de la réalisation du scanner avant tout acte chirurgical impliquant les artères digestives

RESUMO

Spontaneous bilateral intraorbital hematoma is a rare complication of sickle cell disease in children. Imaging examinations are of paramount importance in the diagnosis and conditioning of the management processes in order to avoid complications that can compromise the visual function prognosis.

RESUMO

Arteria lusoria is a rare cause of dysphagia in which dysphagia due to esophageal compression. The upper GI endoscopy does not bring significant element that can orient the diagnosis. The injected thoracic CT scan remains the key examination for the diagnosis of dysphagia lusoria and to characterize the defective artery.

RESUMO

INTRODUCTION: Transcranial Doppler is an effective diagnostic tool to detect sickle cell children at risk for stroke. METHODS: We conducted a cross-sectional descriptive study of Malagasy children aged between 24 months and 15 years (group 1: 57 sickle cell diseases, group 2: 43 controls) to assess the cerebral artery velocimetry in the patient population. Transcranial doppler ultrasound with analysis of cerebral blood flow was performed in children of both groups. RESULTS: In subjects with sickle cell disease, the mean velocity (MV) in the middle cerebral artery was 100.9 ± 26.8 cm/s, pulsatility index (PI) was 0.73 ± 0.20, the difference between the right and left middle cerebral artery (MCA) was 19.8 ± 21.5 cm/s, anterior cerebral artery/middle cerebral artery flow velocity ratio (ACA / MCA) was 0.7 ± 0.2. In children without sickle cell disease, MV: 80.6 ± 19.3 cm/s, IP: 0.79 ± 0.14, ACMr: 17 ± 20.1 cm/s, ACA/ACM: 0,8 ± 0,2. The velocity in children with sickle cell disease was higher than in the control group. Velocities were correlated with hemoglobin and age but not with sex and mean corpuscular volume. CONCLUSION: Cerebral Circulation Speeds are higher in children with sickle cell disease and are influenced by hemoglobin levels and age.
