Intracranial artery stenosis Overview. . What is intracranial artery stenosis? Intracranial stenosis is a narrowing of the arteries inside the brain. . The scalp artery now supplies blood to the brain and bypasses the blocked vessel (see Cerebral Bypass Surgery). Complications from bypass can include stroke, vasospasm, and clotting in the donor vessel.

. including microsurgical clipping using temporary vessel occlusion with mild hypothermia, endovascular coiling and stenting, . Other surgical procedures sometimes performed for revascularization include EDAS (encephalo-duro-arterio-synangiosis), EMS (encephalo-myo-synangiosis) . This often results from rupture of an intracranial aneurysm (see above).

Cerebral bypass surgery Overview. . If you have good collateral blood vessels, the other arteries send enough blood to the brain so there is no change in brain function. The balloon is usually left in place for 30 minutes, then deflated and removed. If you lack collateral connections and not enough blood gets to the brain, you may develop weakness in an arm, or difficulty speaking. . For carotid artery occlusion, .

Although the death rate from stroke has more than halved since 1980 in common with other forms of cardiovascular disease, .

Vascular occlusion. Vascular occlusion is a blockage of a blood vessel, usually with a clot . This can be to reduce pressure on aneurysms (weakened blood vessels) or to restrict a haemorrhage. It can also be used to reduce blood supply to tumours or growths in the body, and therefore restrict their development. Occlusion can be carried out using a ligature; by implanting small coils which stimulate the formation of clots; .

Approximately 80% of all strokes are ischemic (due to occlusion of a vessel). Atherothrombotic occlusion, . While the pathophysiology of atherothrombosis is similar to the pathophysiology of occlusion in many other vascular beds, . Hemorrhagic cerebrovascular disease. Intracranial hemorrhage falls into two major categories: (1) spontaneous hemorrhage .
