In a series of 20 young rats, three cortical lesions were made in each hemisphere. Two of these lesions were filled with avitene and gelfoam, while the third was left empty as a control. The animals were killed successively on weeks 1, 2, 4 and 8 after the operation. The results were as follows : 1) Although there was no difference in the type of tissue reactions, avitene was more rapid and profound than gelfoam in the process and degree of inflammatory reaction at the same periods. 2) Avitene biodegradaded more rapidly than gelfoam. 3) The extent of fibrosis and adhesion to the surrounding brain tissues were not grossly different between these two agents but more profound histopathologically in avitene at the same periods. With these results, we could conclude that the avitene was superior to the gelfoam as the hemostatic agent in neurosurgical area.

The outcome of acute subdural hematoma(SDH) had been generally unsatisfactory. The authors have analyzed the factors influencing the outcome of 70 patients who underwent acute SDH evacuation. Thirty five patients(50%) died and twenty two(31.4%) had a favorable outcome. A significant correlation was found between the outcome and the motor score at operation, the time interval to operation papillary response, type of operation and the Glasgow Coma Scale(GCS) at operation. But the patient's age, the mode of injury, the skull fracture, the degree of midline shift, the hematoma location, the type of brain swelling, the hematoma thickness, and the systolic blood pressure did not correlate with the outcome scale.

Mental deterioration and signs of cerebellar dysfunction developed 5 years after lateral ventricle shunting in 36-year-old hydrocephalic female patient. Fourth ventricle enlargement was seen on CT scan. Reevaluation of the cerebrospinal fluid pathways with metrizamide ventriculography showed isolated fourth ventricle with aqueductal stenosis. Shunting of the fourth ventricle with an Y-connector returned the patient to normal neurological status.

A series of 54 adult patients with intraventricular hemorrhage(IVH) diagnosed by computed tomography(CT) scan and treated with external ventricular drainage were reviewed. In cases who occurred poor drainage of bloody cerebrospinal fluid obstruction, irrigation with urokinase solution(6,000 U/ml) was tried. Hypertension and ruptured aneurysms accounted for 65% of the cases. Although most cases showed poor prognosis, we experienced dramatic improvements in four comatose patients who had fixed dilated pupils after spontaneous intraventricular hemorrhage with secondary acute hydrocephalus. We believe ventriculostomy to be effective in managing IVH especially in the early stage before cerebral herniation occurs. This procedure, accomplished by a convenient and relatively simple technique, led to evacuration of intraventricular blood, or the temporary or permanent cessation of progression of the hydrocephalic process, decrease in ventricular size, and normalization of ICP. However, a relatively high incidence of infection was problematic.

A case of peripheral T-cell lymphoma, large cell type(NIH) is reported. The literature review yielded a rare case report of a malignant lymphoma especially in the even more rare epidural site. The patient's symptoms were relieved by decompressive laminectomy and subtotal removal of mass and combined scheduled chemotherapy with radiotherapy. The pathological examination revealed malignant lymphoma, diffuse, large cell type(NIH) by H & E and immunologic marker analysis.

Primary spinal glioblastoma multiforme is very rare, especially in childhood. 13-year-old boy was admitted to our neurosurgical department because of paraparesis, sensory loss below T10 and sphincter disturbance. Thoracic myelogram showed complete obstruction at T10 level and total laminectomy with partial removal of the intramedullary cord tumor mass was performed under the impression of spinal cord tumor. Postoperatively, his symptoms and signs unchanged. Pathological diagnosis was intramedullary glioblastoma multiforme involving thoracic cord.

Among the four-hundred patients with cerebral aneurysms confirmed by cerebral angiography, we divided them into two age groups, one with ages 39 years or younger(young-aged group: 51 patients, 12.8%), and another with ages 65 years or older(old aged group: 45 patients, 11.3%). A comparison was undertaken in regard to clinical characteristics and overall outcome in two groups. In young-aged group, the female-to-male ratio was 2.2: 1 whereas, women was predominant by five times more in old aged group. Anterior communicating artery aneurysm was the most common site(43.1%) in young-aged group, unlike to old aged group where posterior communicating artery was the most common site(33.3%). The most common symptom was headache in both groups, and the hypertension was more frequent in young-aged group(45.5%) than old-aged group(33.3%). Surgery was performed in 43 patients(84%) in younger group, and 37 patients(82.2%) in elderly group. Young-aged group showed more favorable outcome(91%) than old-aged group(70%).

This study is a retrospective clinical analysis of 134 cases of anterior communicating artery aneurysms surgically treated in the Department of Neurosurgery, Chungnam National University Hospital from January 1990 to December 1996. The results of analysis were summarized as follows; 1) Peak age incidence was in the sixth decade and male to female ratio was 1: 1.2, showing female predominancy. 2) There was no statistically significant relationship between direction of aneurysm and Fisher's grade, and occurrence of hydrocephalus, and also between the direction, size and shape of aneurysm and preoperative Hunt-Hess grade. 3) There was statistically significant relationship between the shape of aneurysm and angiographic vasospasm; there was high incidence of vasospasm in lobulated and oval shape of aneurysm. But there was no statistically significant relationship between the direction, size of aneurysm and angiographic vasospasm. 4) The correlations between outcome and preoperative Hunt-Hess grade, and occurrence of angiographic vasospasm, and temporary clipping were statistically significant; the outcome was good in cases of no vasospasm, temporay clipping and better preoperative Hunt-Hess grade. 5) The direction, shape and size of aneurysm, existence or not of abnormality in circle of willis, timing of surgery and operative procedure had no statistically significant relationship with outcome. 6) Postoperative complications were vasospasm and infarction(18.7%), brain edema, hydrocephalus, in order of frequency, and the mortality rate was 3%.
