Cerebral oxygenation levels during deep hypothermic selective cerebral perfusion were measured with near infrared spectro-scopy (NIRS) as a cerebral monitoring system for 4 patients with thoracic aortic aneurysm. The levels monitored with NIRS were almost stable in 3 of 4 patients. In the other 1 patient, the oxyhe-moglobin level which decreased at the onset of selective cerebral perfusion from right axillar artery increased with additional cerebral perfusion from left carotid artery. The relationship between oxy-hemoglobin level and cerebral perfusion rate had a good correlation in each patient. Cerebral oxy-genation monitoring with NIRS may be useful to establish optimal method of cerebral perfusion for patients with thoracic aortic aneurysm.
