The diagnostic accuracy of three-dimensional constructive interference in steady state (CISS) magnetic resonance (MR) imaging was evaluated for the assessment of idiopathic moyamoya disease. Six consecutive patients underwent MR angiography, CISS imaging, and digital subtraction angiography. MR angiography and CISS imaging visualization of the steno-occlusive changes in the distal internal caro...

Moyamoya disease is a rare cerebrovascular disorder, characterised by progressive stenosis and/or occlusion of the intracranial internal carotid artery and its proximal branches with the development of a basal collateral network. Moyamoya disease has a high prevalence in Asia, particularly in Japan, Korea and China. Ischemic events and intracranial bleeding are the most common clinical manifest...

Moyamoya disease usually manifests as ischemic events in childhood, and as more severe hemorrhagic events, including intraventricular hemorrhage, in adults. Recently, the indication for neuroendoscopic surgery has been extended to cast-formation intraventricular hematomas. However, detailed information about the use of neuroendoscopic surgery for the treatment of intraventricular hemorrhage ass...

Moyamoya disease has been associated with renal artery stenosis, cerebral hemorrhage, and multiple cranial traumas. We report a unique case of moyamoya disease associated with polycystic kidney disease and eosinophilic granuloma. Although the etiology of moyamoya disease is unknown, a familial pattern of occurrence has been documented. Of particular importance is its presentation with polycysti...

Background and purpose: Moyamoya angiopathy (MA) is a progressive cerebrovascular disease with poorly understood pathophysiology. It mainly characterized by bilateral stenosis of the terminal intracranial part supraclinoid internal carotid arteries proximal parts middle anterior cerebral arteries. This results in early-onset ischemic or hemorrhagic strokes. The may be idiopathic (known as disea...

BACKGROUND AND PURPOSE Moyamoya disease is characterized by chronic stenoocclusive vasculopathy involving the distal supraclinoid internal carotid arteries and presents with ischemic or hemorrhagic symptoms. We review advances in the understanding and management of moyamoya disease. SUMMARY OF REVIEW Cerebral revascularization, either direct or indirect, is the cornerstone of treatment for mo...

BACKGROUND AND PURPOSE Clinical features and pathophysiology of postoperative hyperperfusion in moyamoya disease are still unclear. This study was aimed to clarify the incidence and time course of postoperative hyperperfusion and to determine the independent predictors of postoperative hyperperfusion in moyamoya disease. METHODS This prospective study included 41 patients who underwent surgic...
