| Abstract | La maladie de Moya Moya est une maladie angiogenique, caracterisee par un retrecissement de l'artere carotide interne distale qui s'etend aux segments proximaux des arteres cerebrales moyennes et anterieures, induisant la formation de vaisseaux de suppleance. Ces derniers proviennent des collaterales parenchymateuses, perforantes, leptomeningees et autres anastomoses transdurales. Ces vaisseaux collateraux ont un aspect caracteristique a l'angiographie formant un nuage de fumee : reseau Moya Moya. Son etiologie reste encore mal elucidee et represente 10 a 15% des causes d'accidents vasculaires cerebraux (AVC), avec 2 pics d'âge ou l'atteinte est plus frequente: les enfants autour de 5 ans et les adultes autour de 40 ans. Son evolution peut etre lente avec des symptomes intermittents ou etre fulminante avec un declin neurologique rapide. Les donnees actuelles montrent l'importance du traitement chirurgical comme methode de reference pour la prise en charge du syndrome de Moya en particulier chez les patients avec des symptomes progressifs et recidivants.

These vessels come from the collateral parenchymal vessels, the perforating vessels, leptomeningeal vessels and other transdural anastomoses. These collateral vessels have a characteristic appearance on angiography, forming a cloud of smoke: net-like moyamoya. Its etiology is still poorly understood. Moyamoya disease accounts for 10-15% of the causes of stroke, with 2 age peaks at which its occurrence is more frequent: children around 5 years old and adults around 40 years old. Its evolution can be slow with intermittent symptoms or fulminant with fast neurological deterioration. The current data show the role of surgery as the gold standard for the treatment of moyamoya syndrome, in particular in patients with progressive and recurrent symptoms.
