[Aortic arch replacement placing priority on cardiac and cerebral reperfusion].
In this report, aortic arch replacement was performed successfully in 2 cases with our modified method placing priority on the cardiac and cerebral reperfusion, resulting in no postoperative cardiac or neurological complication. One was a 63-year-old man with old cerebral infarction and ischemic heart disease, and the other was a 72-year-old man with severe stenosis of the left common carotid arteries. Our method is similar to so-called "arch first technique". First, the ascending aorta is clamped and proximal anastomosis is accomplished during core cooling, followed by reconstruction of the brachiocephalic arteries under deep hypothermic circulatory arrest. Then perfusion of the heart and brain is restarted, while distal anastomosis is performed. It was proved that the method had several possible advantages such as minimized duration of brain ischemia and deep hypothermia, and elimination of direct cannulation to the branches of the aortic arch and a separate perfusion circuit for the brain.
