The surgical method was combined direct and indirect bypass. The cumulative probability of the primary end point (all stroke and deaths from surgery through 30 days after surgery and ipsilateral recurrent hemorrhage afterward) was analyzed. The angiographic outcome was measured by the following parameters: bypass patency, reduction of basal MMD vessels, improved degree of dilation, and branch extension of the anterior choroidal and posterior communicating arteries (AChA-PCoA).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of the 113 enrolled cases, CT scans revealed pure intraventricular hemorrhage (IVH) in 63 cases (55.7%), pure intracranial hemorrhage (ICH) in 14 cases (12.4%), and ICH with IVH in 36 cases (31.9%). In 74 of 113 hemorrhagic hemispheres (65.5%), the AChA-PCoA was extremely dilated with extensive branches beyond the choroidal fissure. A total of 114 surgeries were performed. No patient suffered ischemic or hemorrhagic stroke through 30 days after surgery. Ipsilateral rebleeding occurred in 5 patients, 4 of whom died of the rebleeding event. The cumulative probability of the primary end point was 0% at 1 year and 1.9% at 2 years. The annual rebleeding rate was 1.87%\/person\/year. The improvement in AChA-PCoA extension was observed in 75 of 107 operated hemispheres (70.1%), which was higher than that in 7 of 105 unoperated hemispheres (35.2%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Revascularization may provide a benefit over conservative therapy for hemorrhagic MMD patients.
