Deep Hypothermic Circulatory Arrest in Patients With High Cognitive Needs: Full Preservation of Cognitive Abilities

These data indicate that high-cognitive patients experienced very little cognitive change as a result of undergoing DHCA. Our assessment strongly supports the adequacy of straight DHCA as a cerebral protectant strategy during short- to moderate-duration circulatory arrest. We found excellent preservation of functional state and no difference from patients undergoing aortic surgery without DHCA.
