title: [Cerebral artery bypass surgery].
abstract: Cerebral artery bypass surgery makes it possible to improve or replace cerebral circulation by bringing blood flow from extracranial arteries into the cerebral arteries or by creating new flow routes between cerebral arteries. Cerebral artery bypass operations play an important role in the treatment of the rare moyamoya disease causing cerebral artery stenosis and disturbances of the cerebral circulation and in the treatment of cerebral aneurysms that are unamenable to treatment with traditional microsurgical or endovascular techniques. Compared with conservative therapy, bypass surgery does, however, not seem beneficial in the prevention of strokes and hemodynamic disturbances of the cerebral circulation associated with atherosclerotic occlusion of the carotid artery.
