Moyamoya Disease in Childs and Adults: A Review of Surgical Treatment

Quintana LM*

Moyamoya Disease is a chronic, cerebrovascular occlusive disease, in which the terminal portions of the intracranial internal carotid arteries and the initial segments of the middle and anterior cerebral arteries progressively become narrowed or occluded. Due to this phenomenon, reduced blood flow to the brain is produced, and tiny collateral vessels at the base of the brain enlarge to become collateral pathways. These vessels are called “Moyamoya vessels” because the angiographic appearance of these vessels resemble the “cloud” or “puff” of cigarette smoke, which is described as “moya-moya” in the Japanese language; also moya-moya is the Japanese word to describe a hazy appearance or an unclear idea about something.
