Does avoidance of cardiopulmonary bypass decrease the incidence of stroke in diabetics undergoing coronary surgery?

Background: The adverse effects of diabetes mellitus on the coronary circulation and the higher incidence of cardiovascular events in diabetic patients are well documented [Johnson 1982]. Improvements in myocardial protection, revascularization techniques, and anesthetic management have had favorable impacts on coronary artery bypass grafting (CABG) outcome in diabetic patients. Despite that, diabetic patients are significantly more likely to have a prior history of myocardial infarction, congestive heart failure, peripheral vascular disease, and hypertension, as well as having a significantly greater baseline serum creatinine.

The innominate artery as an inflow site in coronary reoperations without cardiopulmonary bypass.

The innominate artery was used as an inflow site in 20 patients undergoing redo coronary operations without cardiopulmonary bypass. This technique was adopted when extensive adhesions and old patent grafts were present, to avoid dissection of the ascending aorta and eliminate the risk of graft injury or embolization. This strategy considerably facilitated construction of proximal anastomoses and was associated with favorable perioperative outcomes.
