NCT02834065
In this study the investigator will randomize 273 subjects to deep (\<20°C), low (20.1°C-24°C), or moderate (24.1°C-28°C) hypothermia during aortic arch surgery with circulatory arrest. The primary purpose of this study is to determine the effect of deep vs low vs moderate hypothermia on neurocognitive function, brain functional connectivity, and leukocyte SUMOylation patterns after surgical circulatory arrest in participants.
NCT03921385
* To demonstrate the feasibility of integrating holographic technology as a heads-up display for navigated cranial and spinal neurosurgical procedures. This entails simply displaying the navigation screen currently used by Medtronic Stealth or Brainlab systems as a holographic image that can be positioned closer to the operative field. * To develop a systematic, efficient communication and registration process allowing holographic technology to be potentially utilized as a navigation tool in cranial and spinal neurosurgery. This entails developing software, optimizing connection parameters, and devising registration techniques incorporating line-of-sight fiducial markers to allow the holographic device to function as a navigation instrument.
