To investigate the relationship between cerebral ischemia and cerebral hemorrhage in the patients suffered from moyamoya disease. Method: A total of 32 patients with moyamoya disease were involved in our study, in which, al the patients were undergone computed tomography angiography and CT scan, and confirmed by DSA . Analysed retrospective of Suzuki hierarchical among of Cerebral ischemia,cerebral hemorrhage and cranial CT scan did not show abnormalities. The quantity of Ⅰ stage (9/31、29.0%)is the most one with cerebral ischemia in the patients suffered from moyamoya disease, and the second one is Ⅵ stage(6/31、19.4%);The quantity of Ⅲ stage (8/21、38.1%) is the most one with cerebral hemorrhage in the patients suffered from moyamoya disease, and the second one is Ⅱ stage (6/21、28.6%).Conclution: Cerebral ischemia and cerebral hemorrhage are associated with Suzuki hierarchical in moyamoya patients.Most patients with cerebral ischemia are in Ⅰ stage、Ⅳ stage、Ⅴ stage and Ⅵ stage; most patients with cerebral hemorrhage are in Ⅱ stage、Ⅲ stage.
