Abstract
Nonhemispheric transient ischemic attacks (TIA) occur as a result of diminished flow to the basilar artery and its branches. The importance of the 4 major sources of blood supply was emphasized. Angiographic evaluation of 1700 patients with cerebral symptoms revealed significant subclavian or vertebral stenosis in 244. Since 1972 a direct anastomosis to the adjacent common carotid artery is the selected operative procedure to restore flow to distal arteries. Exposure and completion of the anastomosis requires only a supraclavicular approach and can be performed safely. No deaths or neurological deficits as a result of interruption of cerebral flow occurred. Complications were minor.
