AB  - A patient developed monocular blindness 23 minutes into a temporary balloon occlusion test of the carotid artery, on the side being tested. His vision returned to normal 1 minute after the balloon was deflated. The authors emphasize the importance of complete frequent neurologic examination during this kind of test.
