[Curative effect of surgery on moyamoya disease: an analysis of 47 patients].

OBJECTIVE: To evaluate the effect of surgery on 47 patients with moyamoya disease by retrospective analysis.
 Methods: A total of 47 patients with moyamoya disease were enrolled from August, 2010 to According to the improved treatment in August, 2013, all cases were divided into two groups: a pre-improved group and a post-improved group. According to different surgical methods, they were divided into two subgroups: an indirect revascularization subgroup and a combined revascularization subgroup.
 Results: The cerebral ischemia in 77.4% of patients was relieved after the surgery. There was significant difference in outcomes of patients between the pre-improved group and the post-improved group (P 0.05).
 Conclusion: Surgical treatment can improve the outcomes of patients with moyamoya disease, but there is no significant difference in surgical effects between indirect and combined revascularization.
