Evolving Selective Cerebral Perfusion for Aortic Arch Replacement: High Flow Rate With Moderate Hypothermic Circulatory Arrest

The rate of postoperative neurologic events did not increase with use of higher temperature. The temperature during HCA could be safely increased to 28°C with high SCP flow rate. Use of moderate HCA with SCP during aortic arch replacement permits radical reconstruction of the aortic arch and can avoid the need for deep hypothermia.
