Events of transient ischemic attack, new infarction, and hemorrhage were included. The Kaplan-Meier risk of stroke was calculated.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>RESULTS<\/jats:title>\n<jats:p>\u2002The mean (\u00b1 SD) patient age was 26 \u00b1 13 years (range 2\u201367 years), and the female\/male ratio was 0.9:1. There were 332 cases of ischemia and 196 hemorrhages. Adults had a higher rate of bleeding than children (50.7% vs 14.0%, respectively; p &lt; 0.001). One hundred twenty-two patients were treated conservatively, and 406 patients underwent revascularization procedures. Of 528 patients, 331 (62.7%) had at least 1 year of follow-up (median 39.5 months) and data from these patients were analyzed. Rebleeding and mortality rates in patients with hemorrhagic MMD (n = 104) were higher than in those with ischemic MMD (n = 227) (26.9% vs 2.2% [p &lt; 0.001] and 4.8% vs 0.4% [p &lt; 0.05], respectively). Twenty-five of 60 (41.7%) conservatively treated patients and 8 of 271 (2.9%) surgically treated patients experienced rebleeding events, a difference that was significant in the Kaplan-Meier curve of rebleeding (p &lt; 0.01). An improvement in perfusion was found in 164 of 224 (73.2%) surgically treated patients 1 month after discharge. However, there was no significant difference in the rate of ischemic events in the surgical and conservative groups (18.8% and 28.3%, respectively; p = 0.09). Among the 104 hemorrhagic cases, rebleeding attacks were observed in 25 patients in the nonsurgical group (n = 60) and 3 patients in the surgical group (n = 44) (41.7% and 6.8%, respectively; OR 9.7 [95% CI 2.7\u201335.0]; p &lt; 0.01).<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>CONCLUSIONS<\/jats:title>\n<jats:p>\u2002There was no difference in the sex distribution of Chinese patients with MMD. Patients with hemorrhagic MMD had a much higher rate of rebleeding and poorer prognosis than those with the ischemic type. Surgical revascularization procedures can improve cerebral perfusion and have a positive impact in preventing rebleeding in patients with hemorrhagic MMD.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2014.10.jns132369","type":"journal-article","created":{"date-parts":[[2014,11,25]],"date-time":"2014-11-25T20:51:31Z","timestamp":1416948691000},"page":"392-399","source":"Crossref","is-referenced-by-count":112,"title":["Clinical features and long-term outcomes of moyamoya disease: a single-center experience with 528 cases in China"],"prefix":"10.3171","volume":"122","author":[{"given":"Xing-ju","family":"Liu","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Beijing Tiantan Hospital, Capital Medical University, Beijing, China;
