ReviewLocal brain hypothermia for neuroprotection in stroke treatment and aneurysm repair.
Hypothermia is well known to provide neuroprotection following various brain insults in experimental animals. Two recently completed clinical trials of whole body hypothermia in out-of-hospital cardiac arrest patients' demonstrated significantly improved survival rates and neurologic outcomes. These results provide new excitement and encouragement for clinical application of hypothermia in cerebrovascular disease. ⋯ Lastly, we review potential mechanisms through which hypothermia provides blood-brain barrier protection and reduces edema formation. Clearly, hypothermia has a bright future for cerebrovascular disease treatment if brain cooling can be delivered in a manner that does not compromise the patient or the neurosurgical and intensive care settings. Local brain cooling may be just that new treatment approach.
