Aortic valve replacement in a patient with a brain tumor

We report a case of aortic stenosis with a brain tumor in a 67-year-old man. Although he showed no clinical neurological abnormality, a computed tomography scan revealed a brain tumor. We performed aortic valve replacement under several management techniques to avoid cerebral injury. Two biochemical markers for brain injury, S-100beta and neuron-specific enolase, were measured perioperatively. The postoperative course was uneventful without neurological complication, and the biochemical markers were within the control ranges.
