Moyamoya disease is a chronic cerebrovascular disease with unknown etiology characterized by steno-occlusive changes at the terminal portion of the internal carotid artery and an abnormal vascular network at the base of the brain. Increasing evidence suggests that surgical revascularization such as direct extracranial-intracranial bypass has potential roles not only for preventing ischemic stroke, but also for reducing the risk of re-bleeding in adult patients with hemorrhagic-onset. Based on these observations, we performed direct/indirect combined revascularization surgery for eleven affected hemispheres of ten adult patients presenting with intracranial hemorrhage. The results of revascularization surgeries were favorable in all patients, and no patient suffered cerebrovascular event during the follow-up period.
