IN RECENT years cerebral angiography has been used extensively in the investigation of patients suffering from cerebrovascular disease and is now commonly used to select patients who may benefit from surgical treatment of stenosis of the carotid or cerebral arteries in their cervical course. In a study of the natural history of ischemic cerebrovascular disease, angiography has been performed in a number of patients. This communication examines the contribution made by angiography to the diagnostic problems of cerebrovascular disease and to the assessment of the prognosis.
