Periprocedural stroke and cardiac catheterization.

Case presentation: During cardiac catheterization, a 65-year-old man suddenly complained of nuchal pain, vertigo, and nausea and rapidly became unconscious, presumably from a stroke. The operator was unsure what type of imaging and management should be undertaken in this infrequent clinical setting. He paged the neurologist, asking him to urgently provide a strategy for diagnosis and management.
