The decision of proper time for operation on ruptured aneurysm is a very important tactic of treatment, because of the following major complications after subarachnoid hemorrhage. Recently it is widely accepted opinion that the ruptured aneurysm should receive an early operation for lower mortality and morbidity by preventing possible complications after subarachnoid hemorrhage such as rebleeding, symptomatic vasospasm and even hydrocephalus. Since 1985, we applied early to emergency surgery to the clinically deteriorating or non improving patients after aneurysm rupture and delayed surgery to the ameliorating patients who were placed under close observation. The early to emergency surgery on poor risk patient was performed within 48 hours after recent subarachnoid hemorrhage and delayed surgery was done after 2 weeks. Of the selective 95 poor-condition patients admitted to Kyungpook National University Hospital over the past 4 years from 1984, 60 got early surgeries and 35 delayed surgeries. Among the 60 patients in the early group, 22 patients with considerable intracranial hemorrhage were exempted from this comparative study. A few cases of vertebrobasilar aneurysms were not included in this paper for a little value in significance. In this prospective study, we evaluated the results of early and delayed surgeries of poor risk patients through clinical analyses and comparison, and we could gain better results from early surgeries.

The surgical approach to spinal tumors varies not only with the level and location of the tumor, but also with the type and extent of the tumor. Some of the dumbbell neurofibroma(neurilemmoma) can be removed through simple laminectomy, but usually are approached through two separate incisions by two stages. In this report, posterior and anterolateral approaches in a single stage to dumbbell neurofibroma(neurilemmoma) of the spinal region are described. This approach provides full exposure of intra- and paraspinal portions of the tumor, thus permitting safe dissection and total removal. Six patients who underwent this procedure are described to illustrate its application.

From November 1992 to October 1994, 71 patients with spondylolisthesis underwent transpedicular fixation and fusion using VSP system. Two groups of were studied, in order to compare comcomitant posterolateral and posterior lumbar interbody fusion with regard to operating time, blood loss, degree of reduction, fusion rate, clinical results, and complications. Results showed 31 good, 11 fair, and 3 poor in the posterolateral fusion group and 23 good, 1 fair, and 2 poor in the posterior lumbar interbody fusion group. Implant failure occurred in 2 patients and consisted of screw breakage. Posterior lumbar interbody fusion with internal fixation provides a highly successful method for maintaining interbody height and obtaining arthrodeis.

Fluorescent in situ hybridization using human genomic DNA probes was performed to localize genes encoding the alpha1A and alpha1E of voltage dependent calcium channels (VDCCs) in the human chromosome and the mRNA expression of these two alpha1 subunits of VDCC was demonstrated in the 18 day old embryo (E18) and adult rat brain by in situ hybridization histochemistry. The genes for the VDCC alpha1A and alpha1E were specifically localized on human chromosome 19p13.1 and 1q25, respectively. In 18 days old rat embryos, the mRNAs of the VDCC alpha1A and alpha1E were predominently expressed in the nervous system including brain and spinal cord. In adult rat brain, the expression pattern of each subunit was extremely different. The expression of alpha1A mRNA was strong in the purkinje cells of cerebellum and CA3 area of hippocampus, relatively high level of expression was found in the dentate gyrus, CA1 area of hippocampus, superficial layer of cerebral cortex and olfactory mitral cells. Whereas alpha1E was highly expressed in the dentate gyrus, CA1-3 area of hippocampus, medial habenula nucleus of thalamus and olfactory mitral and internal granule cells and relatively high level of expression was found in the Purkinje cells of cerebellum, cerebral cortex and caudate-putamen. Until now, no neurological disorder has been mapped to 1q25, location of VDCC alpha1E gene. Recently, it has been reported that mutation of VDCC alpha1A gene causes episodic ataxia type 2 (EA-2) and spinocerebellar ataxia 6 (SCA6). These reports comfirm the our experimental results of chromosomal mapping and prominent cerebellar expression of VDCC a1A gene.

C-T guided stereotactic early burr hole aspirations performed on 106 spontaneous deep intracerebral hematoma patients in the Department of Neurosurgery, Kyungpook University Hospital, between January 1992 and December 1993. For average five days following the operation, continual urokinase(UK) irrigation was done for complete removal of the remaining hematoma. Of the patients, 73 who were operated on within three days of bleeding ictus were chosen for analyses and evaluation by factors believed to affect the final results. Eighty six percent was found to have hypertension as it's cause. The hematoma was removed completely in 13.7% of all the patients on post operation 1st day and 45% within 7 days by urokinase irrigation. The site of hematoma in thalamocapsulo-lenticular area showed a rather poor remission rate compared with those in other locations along with a higher mortality rate. By comparison between the time of admission and discharge, the state of consciousness of patients showed much improvement with 440% of the number of alert patients on discharge:motor function also showed significant improvement with 450% good patients number. In case of poor state of consciousness or motor function on admission, the mortality rate was higher. Rebleeding after aspiration was found in 6.8% and in all the cases except one the operation was done within 24 hours of bleeding, which resulted in poor postoperative outcome without improvement. Pneumonia was most common complication during admission followed by hydrocephalus. Mortality rate was 8.2%, most of which resulted from direct brain damage through bleeding. This surgical method is simple, safe and efficient in treating spontaneous deep intracerebral hematoma with no significant outcome difference when compared with early craniotomy.
