ABSTRACT
In order to inquire the most-effective management of increased intracranial pressure(ICP), mannitol, steroid and hyperventilation were used in rabbits after ligation or non-ligation of the carotid artery. Mannitol was more effective than steroid and hyperventilation in the degree of the reduction of ICP. The intracranial pressure was decreased 43~45% for 25~30 minutes after injection of mannitol. Steroid was less effective than mannitol in the degree of the reduction of ICP. But the time of reduction of ICP was longer, that is, the degree of reduction was 24~60 minutes after injection of steroid. Hyperventilation is effective in the initial time only, for 10 minutes after hyperventilation. The degree of ICP reduction was 13.5~16.7 % for 10 minutes after hyperventilation. The combined group, that is three kinds of mangenent were used, is the most effective treatment to reduce ICP of ICP. The degree of the reduction of ICP was 42.1~49.3% for 20 minutes, 47.7~52.5% for 30minnutes. There was no significant difference between and non-ligation group.

We report a case of spontaneous carotid cavernous fistula(CCF) showing low flow shunt, which was successfully occluded in the fistular site of CCF by direct surgical approach via anteromedial, paramedial and Parkinson's triangle intradurally through pterional subte mporal petrosal route extradurally after intermitten temporary clipping of internal corotid artery(ICA) in petrosal portion and proximal to the ophthalmic artery without hypotension, hypothermia, extracorporial circulation, or cardiac arrest.

Nonsurgical management of four cases of the parasagittal epidural hematoma were experienced. Patients were mildly symptomatic or minimal neurological disturbances on admission. Patients were treated conservatively because of stable neurologic sign. All patients had who diastatic fracture and / or suture have become a complete neurological recovery with satisfactory absorption of EDH over a period of 5 to 12 weeks.

Cerebrospinal fluid lactate and intracranial pressure were measured in 24 severely head-injured patients with Glasgow coma scale below 8. Cerebral perfusion pressure, vital sign and CVP were also measured simultaneously. Severely head-injured patients revealed increased CSF lactate and intracranial pressure which have been significantly correlated with outcome. But changes of vital sign, cerebral perfusion pressure and CVP were not correlated with outcome. The elevation of intracranial pressure checked on arrival was statistically significant in correlation to outcome. And the elevation of CSF lactate were correlated with statistically significance in correlation with outcome and lactate level checked on time interval(arrival, 12hr, 24hr, 48hr after trauma). And so CSF lactate levels are statistically more significant than intracranial pressure in predicting prognosis. We will expect good prognosis in severely head-injured patient by reducing intracranial pressure and CSF lactate, oxygenation and increasing cerebral perfusion.

Cryptococcosis of central nervous system in uncommon, but fatal if untreated. We experienced a case of cryptococcal ventriculitis with hydrocephalus. The symptom was an increased intracranial pressure without meningeal irritation sign. It was confirmed by pathology and cytology taken from fibrous material, which caused an obstruction of shunt catheter in the lateral ventricle. We report a case of cryptococcal ventriculitis in 6 years old male child.
