Abstract
We retrospectively studied 85 patients with angiographically demonstrable critical carotid stenosis. None suffered either immediate or delayed complications after angiography. In patients with critical stenosis of the carotid artery, the benefits of cerebral angiography clearly outweigh the small potential risk when the procedure is performed with meticulous attention to technical detail.
