Monitoring of Aorto-Coronary Bypass Graft Flow
Since the report of Johnson et al  in 1969 about the successful placement of saphenous in the distal segments of coronary vessels in a large serie of patients with proximal coronary obstructive disease, this surgery has revolutionized the treatment of such patients. Although the effects of this operative procedure on survival in various patients subgroups remains controversial [2, 3], there is evidence that this technique improves myocardial perfusion and the symptomatic status of the patient [2, 3].
