Moyamoya Disease in Children and Its Surgical Treatment

Moyamoya disease is an unusual form of chronic cerebrovascular occlusive disease characterized usually by bilateral stenosis of distal internal carotid arteries and their vicinity, by a hazy network of collateral circulation at the base of the brain called moyamoya vessels and clinically by recurring hemispheric ischemic attacks in children. This disease was first reported by a Japanese neurosurgeon and many reports and studies on this disease have been published in Japan. We report here the recent progress in the diagnosis of the disease and introduce a newly developed operative procedure which we think is an ideal surgical method for treating this disease in children.
