Objectives : The management of massive brain swelling remains an unsolved problem in neurosurgical field. Despite newly developed medical and pharmacological therapy, the mortality and morbidity due to massive brain swelling remains high. According to many recent reports, surgical decompression with dura expansion is superior to medical management in patients with massive brain swelling. We performed surgical treatment on the first line of treatment, and followed medical management in case with refractory increased intracranial pressure(ICP). To show the quantitative effect of decompressive surgery on the intracranial pressure, we performed ventricular puncture and checked the ventricular ICP continuously during the decompressive surgery and postoperative period. Materials and Methods : Fifty-one patients with massive brain swelling, undergoing bilateral decompressive craniectomy with dura expansion, were studied in this study. In all patients, ventricular puncture was performed at Kocher's point on the opposite side of massive brain swelling. The ventricular pressure was monitored continuously, during the bilateral decompression procedures and postoperative period. Results : The initial ventricular ICP were varied from 13mmHg to 112mmHg. Immediately after the bilateral craniectomy, mean ventricular ICP decreased to $53.1{\pm}15.8%$ of the initial ICP(ranges from 5mmHg to 87mmHg). Dura opening decreased mean ICP by additional 36.7% and made the ventricular pressure $16.4{\pm}10.5%$ of the initial pressure (ranges from 0mmHg to 28mmHg). Postoperatively, ventricular pressure was lowered to $20.2{\pm}22.6%$(ranged from 0mmHg to 62.3mmHg) of the initial ICP. The ventricular ICP value during the first 24 hours after decompressive surgery was found to be an important prognostic factor. If ICP was over 35mmHg, the mortality was 100% instead of additional medical(barbiturate coma therapy and hypothermia) treatments. Conclusion : Bilateral decompression with dura expansion is considered an effective therapeutic modality in ICP control. To obtain favorable clinical outcome in patients with massive brain swelling, early decision making on surgical management and proper patient selection are mandatory.

Objective : The brain temperature is about $0.4-1^{\circ}C$ higher than that of the other peripheral body area. But most of these results have been obtained in normothermic condition. The objective of this study is to evaluate the temperature difference between the brain and axilla, in patients under hypothermia. Methods : Sixty-three patients(37 women and 26 men) who underwent craniotomy with implantation of the thermal diffusion flowmetry sensor were included in this study. The temperature of the cerebral cortex and axilla was measured every 2 hours, simultaneously. The patient group was divided according to axillary temperature hyperthermia( over $38^{\circ}C$), normothermia($36-38^{\circ}C$) and hypothermia(under $36^{\circ}C$). Total 1671 paired sample data were collected and analyzed. Results : The temperature difference between the cerebral cortex and the axilla was $0.45{\pm}1.04^{\circ}C$ in hyperthermic patients, $0.97{\pm}1.1^{\circ}C$ in normothermic patients and $1.04{\pm}0.81^{\circ}C$ in hypothermic patients. The temperature difference has statistical significance in each group(unpaired t-test, p<0.05). Conclusion : From our study the temperature difference between the brain and the axilla in hypothermic condition increased more than that of normothermic state. And in hyperthermic condition, the temperature difference decreased.

We present a modified method for the treatment of brain abscess. The double lumen extraventricular drainage (EVD) catheter which was developed for the intracerebral hematoma management, was applied for the treatment of brain abscess drainage. We placed the double lumen EVD catheter into the abscess cavity by free-hand technique and irrigated the abscess cavity continuously with antibiotics solution for 7 days. Simultaneous intravenous antibiotics was administered for 4 weeks. The continuous irrigation with double lumen catheter was found to be safe and effective treatment modality in the brain abscess.

Neurological symptoms may develope when the blood urea nitrogen is lowered too rapidly by hemodialysis. It is known that these symptoms, known as dialysis disequilibrium are associated with cerebral edema. However, the pathogenesis of brain swelling and neurological deterioration after rapid hemodialysis is controversial. The reverse urea hypothesis suggests that hemodialysis removes urea more slowly from the brain than from the plasma, creating an osmotic gradient that results in cerebral edema. The idiogenic osmole hypothesis proposes that an osmotic gradient between brain and plasma develops during rapid dialysis because of newly formed brain osmoles. Authors report a such case and discuss the possible mechanism and preventive methods.

Objective : Cranioplasty is required to protect underlying brain, to correct major aesthetic deformities, or both. The ideal material for this purpose is autogenous bone. When this is not available, alloplastic or artificial materials may be used. In this study authors compared the infection rate according to the cranioplasty materials(the frozen autologous bone vs. bone cement), and duration of the skull defect. Materials : Between May 1994 and December 1999, 111 patients with skull defect treated with cranioplasty(82 cases of frozen autologous bone and 29 cases of artificial bone material) were included in this study. There were 77 males and 34 females with a mean age of 41.4 years(range 1-85 years). 57 patients had head trauma and 54 had non-traumatic insults. According to the duration of skull defect, there were 28 cases under 1 month, 33 cases of 1-2 months, 15 cases of 2-3 months, 20 cases of 3-6 months and 15 cases over 6 months of duration. Results : Overall infection rate was 9.9%. In cases with frozen autologous bone and artificial bone material, the infection rate was 8.5% and 13.7%, respectively. The infection rate according to the duration of skull defect was 3.6%(among 28 cases) under 1 month of age, while those were 12%(4 among 33 cases) at 1-2 months, 20%(3 among 15 cases) at 2-3 months, 5%(1 among 20 cases) at 3-6 months and 13%(2 among 15 cases) over 6 months. Accoring to the underlying disease, the infection rate in traumatic cases was 12%(7 among 57 cases) and that in non-traumatic one was 3.7%(2 among 54 cases). Conclusion : From this study, it appears that skull defect should be repaired as soon as possible, because early cranioplasty can lower the infection rate. And surgeons could save the patients' cranial bone as possible as they can because autologous bone is not only cost effective in cosmatic purpose but lower the infection rate.

MMD의 외과적 치료에서 소아에서는 직접 및 간접적인 혈관문합술을 병합하거나 아니면 간접적인 혈관문합술들을 병합하여 시행하는 경향이 있고, 성인에서는 혈관의 직경이나 MMD의 진행속도로 보아 STA-MCA 문합술과 같은 직접적인 수술이 많이 활용되고 있으나, 소아나 성인에서나 모두 공통적으로 보다 넓은 뇌표면에 여러 가지 수술방법을 병합하는 것이 좀더 광범위한 범위에 뇌혈류 공급을 증가 시키는데 도움이 된다고 보는 경향이다. 수술의 적응증은 혈관조영상에서의 나타난 질병의 정도보다는 acetazolamide를 이용한 PET 나 SPECT 검사로서 뇌혈류 예비량에 기준을 두고 있는 현상이 혈류 역학적으로도 합리적인 것으로 보인다. 수술후 합병증을 줄이려면 수술중에 정상탄산, 정상체온, 정상혈압을 유지 시킴과 동시에, 수술직후 통증관리도 철저히 하는 것이 매우 중요하다. The authors reviewed the recent trend of surgical treatment for pediatric as well as adult onset moyamoya disease(MMD). Combined direct and indirect arterial anastomosis or multiple indirect arterial bypasss has been increasing for pediatric MMD and direct arterial bypass is recommended for adult MMD, especially in patients with hemorrhagic MMD. Besides perioperative complications related to the management of MMD and 1999 annual report by the Research Committee on Spontaneous Occlusion of the Circle of Willis(Moyamoya Disease) of the Ministry of Health and Welfare, Japan will be summarizd.

We present two cases of deep cerebral venous thrombosis(DCVT) with the totally occluded straight sinus. A 42-year-old female received with altered mentality . She has taken antihistamine for six years to treat the paranasal sinusitis. Another 34-year-old female who used the oral contraceptive for 11 months presented with acute behavior change . Both of these patients were diagnosed by computed tomography(CT), magnetic resonance(MR) imaging, and cerebral angiography. They were fully recovered with systemic urokinase thrombolysis followed by heparin therapy. We report that the intravenous thrombolysis was potentially effective management strategy in our cases of DCVT with the totally occluded straight sinus.

Intradural extramedullary hemangioblastoma of the spinal cord is uncommon tumor. Symptom onset is typically in the forth decade. Complete excision offers the best chance for cure. We report a case of extramedullary hemangioblastoma of the spinal cord in old age. A 76 -year old man presented with 1 month history of paraparesis. Multiple enhancing lower thoracic and lumbar spinal masses were seen on magnetic resonance imaging(MRI). Surgical exploration for symptomatic lesion revealed intradural-extramedullary mass, which had hypervascularity. The excised spinal masses were diagnosed as hemangioblastoma. Postoperative course was uneventful and symptoms improved gradually.

Crowth of an angiolipoma of the central nervous system is rare. Only about 60 cases were searched in the literature. We report one case of spinal angiolipoma recently treated in our institution. A 67-year-old man was admitted because of burning sensation on the both lower extremities and paraparesis. He felt burning sensation on the both great toes and it progressively involved to thighs and inguinal area during the past 1 year which gradually worsened. MR image showed a spinal mass lesion at the level of T4 to T6. The lesion was isodense and hyperdense in periphery on T1-weighted image and hyperintense on T2-weighted image. The tumor was located on the posterior area of the spinal cord and markedly enhanced after intravenous Gd-DTPA. At the operation, a soft, dark-red mass was totally removed. On histological examination, the tumor was shown to be mainly composed of mature fatty cells and numerous blood vessels with enlarged lumens. Postoperative course was uneventful and the symptoms improved gradually.
