PROLONGED HYPOTHERMIA IN REFRACTORY  INTRACRANIAL HYPERTENSION. REPORT OF ONE CASEThe use of hypothermia after cardiac arrest caused by ventricular fibrillation is a standard clinical practice, however its use for neuroprotection has been extended to other conditions. We report a 23 years old male with intracranial hypertension secondary to a parenchymal hematoma associated to acute hydrocephaly. An arterial malformation was found and embolized. Due to persistent intracranial hypertension, moderate hypothermia with a target temperature of 33°C was started. After 12 hours of hypothermia, intracranial pressure was controlled. After 13 days of hypothermia a definitive control of intracranial pressure was achieved. The patient was discharged 40 days after admission, remains with a mild hemiparesia and is reassuming his university studies.
