Clinically Relevant Anatomy[edit | edit source]
Moyamoya Disease is a disorder of some of the blood vessels in the brain: the internal carotid arteries, and the arteries which branch from them. It is a rare cause of Stroke and TIAs.
It can also be referred to as Progressive Intracranial Occlusive Arteropathy, or Progressive Intracranial Arterial Occlusion.
Mechanism of Injury / Pathological Process
[edit | edit source]
The affected arteries become increasingly constricted with time, and a collateral circulation develops around the constricted arteries to compensate for the blockages. The condition is an idiopathic, non-inflammatory, non-atherosclerotic progressive vaso-occlusive disease involving the terminal supraclinoid internal carotid arteries and circle of Willis.
Clinical Presentation[edit | edit source]
The patient often presents either in childhood, aged around 5 years, or in adults in their 30s or 40s.
