Cranial Artery Bypass Neurosurgeons today are involved in many areas of general concern. One of these, occlusive cerebrovascular disease, is a prevalent and potentially devastating problem, and a great effort is under way to prevent or treat this disorder. Extracranial-intracranial arterial bypass to circumvent obstruction of the carotid and vertebral arteries in the neck or base of the skull has received wide attention. It involves the anastomosis of vessels of 1 to 2 mm in diameter from the scalp to vessels of similar diameter on the surface of the brain. When performed by experienced neurosurgeons using microsurgical technique, the operative mortality and morbidity are low (less than 5%).1 Typically, these small vessels can adequately perfuse brain areas made ischemic by proximal occlusive lesions. For example, proximal surgical occlusion of the middle cerebral artery to trap a distal giant aneurysm is often tolerated if a distal middle-cerebral arterial branch is
