Figure 3From: Ischemia monitoring in off-pump coronary artery bypass surgery using intravascular near-infrared spectroscopyNIR spectra of a patient receiving a distal venous anastomosis to a diagonal branch prior to the LITA – LAD anastomosis. At 760 nm a slight increase (deoxy-hemoglobin) was registered. Decrease of the curve after completing the arterial anastomosis to the LAD with the LITA graft.Back to article page
