A series of 1909 computed tomography(CT) scan performed for head injury mostly after traffic accident was retrospectively reviewed. 17 patients were found to have clearly definable traumatic intraventricular hemorrhage(TIVH). TIVH was associated with various brain lesions in most cases; Intracerebral lesions with contusional hemorrhage and subdural hematoma(Glasgow Coma Scale Score) coexisted in 6 and 5 instances. The outcome(Glasgow Outcome Scale) of this series was related with initial clinical findings, and 11 patiens survived. We have designed this study to assess the occurrence of TIVH in our series of head-injured patients in Korea, and to correlate these findngs with the clinical status, the presence of associated lesions, and their relation to final outcome of these patients, and conculsions are as follows: 1) The incidence of TIVH and its associated mortality is 0.9% and 35.3%, respectively, Most of them occurs below 5 th decade(70.6%) with male predominace(88.2%). 2) Mode of injury is mainly from traffic accident(94.1%), followed by fall down(5.9%). 3) The presence of concomitant lesions has a definite influence on poor outcome(P<0.02), whereas skull fracture or multiplicity of TIVH deos not. 4) Primary impact site to induce TIVH is primarily on frontal portion(58.9%). 5) With regard to brain stem injury in TIVH, the final outcome clearly depends on pathological demonstration on CT(P<0.005%), but not on location of hemorrhage(P<0.5%).

The diagnosis and appropriate management of blunt abdominal trauma including retroperitoneal hematoma associated head injury is difficult. In our case, psoas muscle hematoma was revealed during the evaluation of fever. Psoas muscle hematoma most commonly results secondarily from coagulation defect or from retroperitoneal bleeding into the psoas sheath. The presenting signs and symptoms of this case are hypotension and anemia. Pain is also present in the back or abdomen. If it is associated with head injury and not presented massive hemorrhage, the actual diagnosis is not easy. The appropriate management depends on a careful initial evaluation including suspicion of physician, repetitive physical examination, the timely use of diagnostic procedures.

OBJECTIVE: TA retrospective study is performed on 28 patients with primary intraventricular hemorrhage(PIVH) to examine the outcome and prognostic factors associated with this disorder. METHODS: Clinical data collected between 1998 and 2002 was used in the present study. The outcomes of these patients were compared by age, etiology, initial Glasgow Coma Score(GCS), Graeb's score, ventriculocranial ratio(VCR), hemorrhagic dilation of the third ventricle, and hemorrhagic dilation of the fourth ventricle. The Glasgow Outcome Scale(GOS) at discharge was used for the comparison of outcomes. RESULTS: The mean age of these patients was 48.4+/-17.4 years. The underlying causes of PIVH were hypertension(53.6%), moyamoya disease(17.9%), arteriovenous malformation(10.7%), cerebral aneurysm(7.1%), and unknown(10.7%). The age and etiology were not correlated with outcome. Patients with a GCS of 13-15 showed a good outcome in 90.5%(p<0.05). Those with a higher VCR(> or =0.23) showed a poor outcome in 64.3%(p<0.05). Patients with a Graeb's score of 9-12 showed a poor outcome in 87.5%(p<0.05). Those with hemorrhagic dilatation of the third ventricle showed a poor outcome in 80.0%, and those with hemorrhagic dilatation of the fourth ventricle showed a poor outcome in 85.7%(p<0.05). The overall mortality rate was 17.9%. CONCLUSION: Low initial GCS, high Graeb's score, high VCR, and hemorrhagic dilatation of the third ventricle or the fourth ventricle are correlated with poor outcome in PIVH.

Five separate incidences of patients with cerebrovascular disease(CVD) were revealed among 555 craniocerebral traumatic victims between 1991 and 192. The 5 cases of with cerebrovascular disease revealed included 3 aneurysm. 1 arteriovenous malformation and 1 spontaneous intracerebral hematoma caused by angiographic study. The frequent use of computerized tomographic scans in the evaluation of head-injured victims can well demonstrate an intracerebral hemorrhage, but may not ge able to detect the associated cerebrovascular disease;whereas the efficacy of angiogrphy, on the contrary, has been losing its popularity as diagnostic armamentarium. The importance of angiographic study should be considered, if clinical signs and/or brain CT ideate the possibility of cerebrovascular disease even during the course of head injury management.

Intraventricular hemorrhage after blunt head trauma, which reflects the severity of head injury, is uncommon. A retrospective study of 109 traumatic intraventricular hemorrhage(TIVH) patients who were admitted between January 1, 1988 and December 31, 1993 was conducted. The results are as follows: 1) Incidence of TIVH and its associated mortality were 2.45% and 28.4%, respectively. 2) TIVH-associated radiological abnormalities were traumatic intracerebral hematoma(62.7%), skull fracture(42.7%), and traumatic subarachnoid hemorrhage(34.5%). 3) Amount of TIVH was related to traumatic intracerebral hematoma(p=0.0003) and traumatic subarachnod hemorrhage(p=0.0385). 4) The poorest prognostic indicator was associated abnormalities, especially corpus callosum or brainstem hemorrhage(p=0.0099). 5) TIVH-associated hydrocephalus was not related to the amount of TIVH(p=0.42), and poor prognosis(p=0.12). 6) Patients with TIVH showed better Glasgow coma scale and Glasgow outcome scale than TIVH-associated abnormalities.

OBJECTIVE: The aim of this study is to evaluate of the significance of intraoperative electrophysiologic monitoring and follow up electrophysiologic study at seven days after microvascular decompression(MVD) for hemifacial spasm(HFS). METHODS: Thirty nine patients with hemifacial spasm were included in this study and were treated with MVD of the facial nerve from Jun 1990 to May 2001. The patients were divided into a monitoring group and a non-monitoring group. We compared the surgical outcomes, operation related complications between two groups. The abnormal muscle response(AMR) of preoperative electromyographic recording appeared on the mentalis muscle during stimulation of the zygomatic branch of the facial nerve was compared with those of changed during operation, immediately after operation and at postoperative 7th day(POD 7). The relationship between degree of AMR disappearance and surgical outcome was analyzed. RESULTS: There was no difference in surgical outcomes but significant difference in the incidence of operation-related complications between two groups. The results of electrophysiologic study at POD 7 were significantly correlated with surgical outcome in the monitoring group. CONCLUSION: The electrophysiologic study is helpful for identifying the offenders, determining the adequacy of vascular decompression and decrease of operation-related complications. The clinical and electrophysiologic status of HFS after MVD has continuously changed, and therefore the results of eletrophysiologic study at POD 7 are useful for predicting the surgical outcome.

Dural arteriovenous malformations(AVM) are not uncommon. Reports of intracranial dural AVM have been increasing but most of them deal with dural AVM in the region of the cavernous sinus, posterior fossa and tentorium, but those of the anterior cranial fossa are very rare. Recently, we experienced two cases of right frontal dural arteriovenous malformation fed mainly by both ethmoidal arteries. The angiographic appearance in these two cases is quite uniform. The nidus was located in the frontal dura, although their main feeders were dural arteries. They were drained through an intracerebral cortical vein associated with aneurysmal dilatation of proximal portion into superior sagittal sinus. Spontaneous intracerebral hematoma was the cause of the clinical symptoms. We report two cases of intracerebral hematoma, caused by dural AVM, which was successfully managed by surgical treatment.

Among 1350 craniocerebral trauma patients treated between January 1992 and December 1995. The authors analyzed 25 who had suffered combined head and spine trauma and had been subject to follow up. The ratio of males to females was 4 : 1 ; their ages ranged from less than twenty to over sixty. As clinical parameters, we use of the Glasgow Coma Scale(GCS), Revised Trauma Score(RTS) and Glasgow Outcome Scale(GOS) at discharge, and for clinical statistics, used the chi-square test. The results of the study were as follows : 1) Among craniocerebral trauma patients, the incidence of combined head and spine trauma was 2%(25/1350). 2) In cases with combined craniospinal trauma, the incidence of intracranial hemorrhage and cervical spine injury was 76% and 68%, respectively. 3) Among cases with spinal injury, head trauma combined with cervical spine injury showed the worst outcome (p<0.05). 4) Combined high cervical spine injury showed a poorer outcome than did lower cervical spine injury(p<0.05). 5) Initial GCS was significantly related to initial RTS(p<0.05). 6) At discharge, there was a very highly significant correlation between initial GCS and GOS(p<0.01), but not between initial RTS and GOS(p<0.081). 7) Especially in patients who are unconscious because of head trauma, it is important to investigate the possibility of spinal injury other than that of at cervical level.

A retrospective analysis of 60 patients with traumatic subdural hygroma who had been managed and followed up at least 6 months, was done in relation to time of development and associated intracranial lesion, initial Glasgow Coma Scale(GCS), sequeritial changes of subdural hygroma, and Glasgow Outcome Scale(GOS). The incidence of traumatic subdural hygroma was 8.4%, 131 cases among 1,563 head-injured cases. And most of them was subacute from(55%, 33 cases among 60 cases), complex subdural hygroma was 65%(39 cases among 60 cases). The conversion rate of traumatic subdural hygroma into chronic subdural hematoma was 15%(9 cases among 60 cases). There was no statistically significant relation between initial GCS score and time of development and also intial GCS score and development of complex subdural hygroma and time of development and GOS of 6 months follow-up(P>0.05). There noted only highly significant relation between initial GCS score and GOS of 6 months follow-up(P<0.001).
