Disclosed is an apparatus and method for reducing secondary brain injury. The apparatus includes a brain-cooling probe and a control console. The brain-cooling probe cools the brain to prevent secondary injury by cooling the cerebrospinal fluid within one or more brain ventricles. The brain-cooling probe withdraws a small amount of cerebrospinal fluid from a ventricle into a cooling chamber located ex-vivo in close proximity to the head. After the cerebrospinal fluid is cooled it is then reintroduced back into the ventricle. This process is repeated in a cyclical or continuous manner in order to achieve and maintain a predetermined brain ventricle temperature lower than normal body temperature. The apparatus and method disclosed provides effective brain ventricle cooling without the need to introduce extra-corporeal fluids into the brain.
