Compared to deep hypothermia, mild and moderate hypothermia were associated with lower mortality (mild vs. deep: odds ratio [OR] 0.50; 95% confidence interval (CI) 0.29\u20130.87, moderate vs. deep: OR 0.68; 95% CI 0.54\u20130.86). In addition, mild hypothermia was associated with lower stroke (OR 0.50; 95% CI 0.28\u20130.89), AKI (OR 0.36; 95% CI 0.15\u20130.88) and postoperative bleeding (OR 0.55; 95% CI 0.31\u20130.97) compared to deep hypothermia. There was no significant difference between mild and moderate hypothermia in mortality, AKI or bleeding occurrence, while mild hypothermia was associated with shorter operative time and hospital stay. There was no significant difference in TIA rate among three groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Mild hypothermia was associated with overall more favorable clinical outcomes with comparable neurological complications compared to deep hypothermia.
