Occlusions bilatérales de la carotide interne associée à une circulation de suppléance cortico-corticale, transdurale, et du type "moya-moya" chez l'enfant noir

Five cases of black Senegalese children aged from 8 to 16 years are reported. In each case bilateral obstruction or stenosis of the internal carotid arteries was demonstrated with a basal leash of vessels (the "rete mirabile" or "moya-moya" of the Japanese authors) and with cortico-cortical and transdural anastomoses. An aetiopathogenetic study of these cases and of those reported in the literature has shown that this syndrome is not confined to the Japanese and that it is a disorder of the cerebral circulation which may result from diverse causes, including congenital anomalies of the vessels, neonatal anoxia, specific or non-specific arteritis, various infections and various cardiac abnormalities. © 1972.
