The word cerebrovascular is made up of two parts – “cerebro” which refers to the large part of the brain, and “vascular” which refers to arteries and veins.
Cerebrovascular disease refers to any and all disorders wherein a part of the brain is affected (whether temporary or permanent) by bleeding or ischemia with cerebral blood vessels being involved. It may include carotid, vertebral and intracranial stenosis, aneurysms, strokes and vascular malformations.
Restrictions in blood flow may occur from vessel narrowing (stenosis), clot formation (thrombosis), blockage (embolism), or blood vessel rupture (hemorrhage). Lack of sufficient blood flow (ischemia) affects brain tissue and may cause a stroke.
Treatment: Treatment is cerebral revascularisation using a STA-MCA bypass or a high-flow bypass in selected cases.
