Brain tissue perfusion during pulmonary endarterectomy - The impact of controlled regional cooling

< 40%) occurred in 22.2% of Aurora patients versus 77.8% of Controls (p = 0.030). Postoperative NSE levels were lower in the Aurora group; however, the difference did not reach statistical significance (p = 0.087).ConclusionDual-modality cooling combining extracorporeal hypothermia and targeted head-neck cooling improved intraoperative cerebral oxygenation and were associated with lower postoperative NSE levels; however, due to the limited sample size, no definitive conclusions regarding neuronal injury can be drawn.
