Two cases of carotico-cavernous fistula, which experienced at Dept. of Neurosurgery of Busan National University Hospital, are presented with a brief review of the literature. Because it is the very interesting disease. These were of spontaneous onset. One was 39 year-old woman who was treated with the ligations of internal and common carotid artery in the neck, another was 17 year-old boy treated with the ligations of internal and common carotid artery followed by intraluminal mascular embolization. This surgical management was successful and there was neither recurrence nor other neurologic deficit.

This study was carried out to find out changes in regional cerebral blood flow(r-CBF) in relation to(i) clinical status of patients with subarachnoid hemorrhage due to ruptured intracranial aneurysms ; (ii) the degree of subarachnoid hemorrhage as indicated by brain CT scanning ; (iii) the severity of angiographic vasospasm, and (iv) other neuropathological condition. Measurement of r-CBF were performed, using 133Xe inhalation method, on 50 patients with ruptured intracranial aneurysms. Some of the major findings were as follows : 1) The degree of abnormalities of blood flow correlated well with the clinical severity of neurological deficits. 2) A marked reduction in r-CBF was found in patients with intracerebral hematoma, ischemic lesion and hydrocephalus. 3) In angiospasm area, r-CBF was found in patients with intracerebral hematoma, ischemic lesion and hydrocephalus. 3) In angiospasm area, r-CBF decreases below 30ml/100gm/min in almost all of the patients, and severity of vasospasm correlated with the decrease of CBF. 4) The measurement of CBF on patients with subarachnoid hemorrhage was thought to the useful for foreseeing the clinical outcome of the patients.

Recent technological advances in ultrasound instrumentation have resulted in equipment that will image in "real-time" slices of the human brain similar in quality to computerized tomography(CT). Multiple authors have attested to its usefulness in locatin, characterizing, and facilitating in the biopsy or removal, or both, of intracerebral masses. In this study, the author has examined the efficacy of intraoperative neurosurgical ultrasound in 18 patients who were admitted to the Department of Neurosurgery, Kyung Hee University Hospital. The results were as follows : 1) It can provide critical assistance in precise localization of subcortical masses, since in many instances the overlying surface of brain provides no clue for localization. 2) This technique is very useful for the identificantion of deep lesions, provding infromation about their solid and cystic components and about the shortest route of access to tumor. 3) It provides precise information to help guide biopsy needles into deep lesions, and to confirm their presence within the lesion itself. 4) The system is highly accurate in visualizing ventricular catheters during and after their placement. 5) The system is inherently safe for the patient and the operating room personnel since there is no radiation exposure.

4.The Relationship of Total Leucocyte and Pseudo-eosinophilic Neutrophil Counts with Severity of Injuries and Prognostic Significance of Experimental Craniocereral Injuries in Rabbits.
Journal of Korean Neurosurgical Society 1974;3(2):65-76
Author has attempted to measure serial blood leucocyte and pseudoeosinophilic neutrophil counts to study the inter-relationships between blood total leucocyte levels and severity with prognostic significance of various craniocerebral injuries induced experimentally in rabbits. The experiments were performd on 31 rabbits of male sex, weighing between 1.5 and 1.7kg. On the degree of difference and severity of experimental injuries the animals were divided into the following 6 different groups;subarachnoid hemorrhage(Group I), local brain malacia(Group II), intracerebral hematoma(Group III), intraventricular hematoma(Group IV), unilateral carotid ligation(Group V), bilateral carotid ligation(Group VI). In each groups, total leucocyte and pseudoeosinophilic neutrophil counts were measured at times 1 hr., 3 hr., 6 hr., 12 hr., and 1, 2, 3, 4 day, respectively, after the injuries. The following results were obtained: 1. Mean levels of total leucocyte and pseudoeosinophilic neutrophil counts were 7263(193/mm3 and 35.1% in the control group. 2. The injured group, when compared to the control group of animals, had significantly raised total WBC and pseudoeosinophil counts at 3 hr. after the injuries, and the counts were returned to normal range at the third day after the injuries. 3. In each series of the unilateral carotid ligation, the raised total WBC and pseudoeosinophil counts did not differ significantly in the right ad left series each other. 4. Total WBC and pseudoeosinophil levels in the group of bilateral carotid ligation were progressively increased and the highest levels were seen between 6 hr. and 12 hr. after the injuries. 5. The most raised total WBC and pseudoeosinophil levels were seen in the group with bilateral carotid ligation and the next group was intraventricular hematoma, and the least raised group was subarachnoid hemorrhage. 6. It was concluded that the data showed highly significantly positive correlation between total WBC and pseudoeosinophil counts with the severity of injuries and its prognosis of craniocerebral injuries of rabbits induced experimentally. The greater increase in serial total WBC and pseudoeosinophil counts was seen in the group associated with higher degree of injuries, and the counts became to normal range at the third day with parallel to the degree of recovery after the injuries.

5.Bifrontal Decompressive Craniectomy in Severe Craniocerebral Injury.
Journal of Korean Neurosurgical Society 1973;2(2):65-70
A clinical analysis for bifrontal craniectomy had been carried out with 30 cases at Busan National University Hospital during the period from July of 1972 to June of 1973. The patient's conditions such as bilateral dilated fixed pupils, decerebrated rigidity, apneic respiration, and coma were sometimes regarded to contraindication for the department of neurosurgery to operate. This wide procedure enabled to allow identification of confused and lacerated brain, evacuation of acutely accumulated blood and necrotic brain, and decompression of swollen brain under direct visualization. The author reviews 30 cases operated, and among them, 6 were survived. Before report this technique, we did not operate on the patients who exhibiting apnea and bilaterally dilated fixed pupils. Such clinical signs are commonly preceded to death, and we have recommended conservative therapies such as hyperosmolar agents and steroids to combat brain swelling in this desperately ill patient. Our clinical impression that bifrontal decompressive craniectomy was useful for severe craniocerebral injury and swelling was unable to prove with unequivocal documentation from these cases that their survival was uniquely attributable to the bifrontal craniectomy. I presents my appraisal of the case material, not so much as proof of it's superiority over other methods, but rather as provocation for further critical appraisal of it's use.

Extradural hematomas are usually acute and rapidly progressing and the lucid intervals generally varies from a few moments to several hours. However, not uncommonly, an epidural hematoma may have a lucid interval lasting weeks, months or even years, which may present as a chronic epidural hematoma. Two cases have recently come under our care, demonstrating a paucity of objective neurologic abnormalities, but with extensive compressive extradural hemorrhage, which were found incidentally during the screening examination with the CT scanning.

Traumatic subdural hygroma has received little attention in the literature, the authors experienced 17 cases of traumatic subdural hygroma after introduction of Computerized Tomography(CT) since October 1977 in Kyung Hee University Hospital. Characteristics in CT of our experienced traumatic subdural hygromas were almostly bilateral and located on the anterior aspect of the interhemispheric fissure, frontal and frontotemporal side with decrease density as like cerebrospinal fluid. Subdural hygroma easily differentiated with subdural hematoma by use of the CT scan. Subdural hygroma usually respond readily to evacuation of watery yellowish or cerebrospinal fluid-like fluid through simple burr hole, conservative treatment effected only 3 cases out of 17 subdural hygromas.

Journal of Korean Neurosurgical Society 2009;45(3):196-198
Hemifacial spasm (HFS) is almost always induced by vascular compression but in some cases the cause of HFS are tumors at cerebellopontine angle (CPA) or vascular malformations. We present a rare case of hemifacial spasm caused by epidermoid tumors and the possible pathogenesis of HFS is discussed. A 36-year-old female patient presented with a 27-month history of progressive involuntary facial twitching and had been treated with acupuncture and herb medication. On imaging study, a mass lesion was seen at right CPA. Microvascular decompression combined with mass removal was undertaken through retrosigmoid approach. The lesion was avascular mass and diagnosed with an epidermoid tumor pathologically. Eventually, we found a offending vessel (AICA : anterior inferior cerebellar artery) compressing facial nerve root exit zone (REZ). In case of HFS caused by tumor compression on the facial nerve REZ, surgeons should try to find an offending vessel under the mass. This case supports the vascular compression theory as a pathogenesis of HFS.
