Selective therapeutic cooling is a promising technique for reducing final infarct volume and improving outcomes in ischemic stroke, especially as research regarding brain reperfusion continues to be explored. A recent study provided promising results on the safety and feasibility of selective therapeutic hypothermia via a closed-loop cooling catheter system for intra-carotid blood cooling in an ovine stroke model, but they failed to find efficacy of this method in this model. It is a major step forward from bench to bed side, but enhancing benefits of selective therapeutic cooling may need to take into account a more targeted induction of brain hypothermia and should mitigate potential side effects related to inducing hypothermia.
