Can near infrared spectroscopy predict stroke in coronary artery by-pass graft?

Aim: Central nervous system may be affected after coronary artery by-pass graft (CABG) and carotid stenosis is an important risk factor. Near infrared spectroscopy (NIRS) used to measure the regional cerebral oxygen concentration (rScO2). The aim of this study determine relationship rScO2 in patients with lesion relation stroke changes.
 Material Method: who had cardiac bypass surgery were involved study. Demographic characteristics presence stenosis, collected from files. Bilateral rSO2 measurements performed by 2 sensors. RScO2 values are detected 5 minutes cross-clamp (XCL5), XCL30, XCL60, XCL90, XCL120 by-pass.
 Results: 57 (40 male mean age 62.54±13.08). 17 (29%) stenosis. levels statistically significantly decreased post-clamp 30 minutes. Three (5.2%). Two while one patient did not have. 
 Conclusion: irrespective degree cross-clamp. Cerebral perfusion follow-up during CPB NIRS a method that can for purpose.
