Rapid administration of solution containing dextroae results in marked hyperglycemia and osmotic diuresis hut a balanced electrolyte solution containing maltese does not increase blood sugar. 30 patients were chosen at random and divided into 3 groups j.e, one group received 5% dextrose in water, the second group received Hartmann solution and the third group, 5% maltose in a balanced electrolyte solution. The Patient's blood was collected in the operating room prior to the start l.V. infusion, for the measurement of blood sugar, insulin, osmolarity and electrolrtes in various conditions of N.P.O. Intravenous fluid was administered at a rate of 10 m1/kg/hour while anesthesia was induced and maintained with an endotracheal tube in place. Blood samples were taken one hour. 2 hours and 3 7ours f:on the time 1,V. infusion started, In the of 5% dextrose in water groups, the value of blood sugar and insulin was 88.5+/-12.1 mg% and 14.60+/-7.67 un/ml at NPO, 257.7+/-60.8mg% and 70.75+/-37.55 un/m1 at 1 hour, 298.8+/-84.4mg%: and 143.19+/-50.32 un/ml at 2 hours and 228.6+/-75.8% and 127.71+/-56.98 un/m1 at 3 hours. Although the b1ood sugar and insulin values increased markedly. but potassium and chloride were 4.74+/-0.55 mEq/l and 101.1+/-2.9 mEq/l and 4.11+/-0.31 mEq/l, 107.4+/-2.3 mEq/l and 3.75+/-0.41 mEq/l, 176.4+/-2.7mEq/l and 3.89+/-0.50mEq/l, 106.3+/-2.2 mEq/l and shoewed mild decrease, by the way, osmolarity and serum sodium did not changed. In contrast to the 5% dextrose in water groups, there are no changes in the blood glucose. insulin levels, osmolarity or and electrolrtes in the either Hartmann or Elitol (Elitol=5% maltose contained in a balanced electrolyte solution) groups. There was a slight increase in osmolarity with maltose but it was not significant. Accordingly it is concluded that rapid infusion of harmann or 5% maltose contained ina balanced electrolyte solution affects the blood sugar and insulin levels insignificantly compared to the dextrose cont5aining solution which increase the blood sugar and indulin levels markedly.

A case of multiple hemangioendothelioma of the cauda equina nerve roots and conus medullaris is described. This case is the first report of intradural multiple hemangioendothelioma in Korea. A 74-year-old woman presented with a 4-month history of progressive bilateral leg weakness and lancinating leg pain especially at night. Magnetic resonance image revealed multiple enhancing nodular masses in the cauda equina nerve roots and pial surface of the conus medullaris. We performed total removal of conus medullaris mass and partial removal of two nerve rootlets masses. Two lesions were histologically examined and found to be hemangioendotheliomas

OBJECTIVE: The purpose of this study was to compare clinical findings and outcomes of Enterprise and Solitaire stent-assisted coiling (SAC). MATERIALS AND METHODS: Between January 2012 and March 2014, 86 patients (mean age, 60.3 years) harboring 89 aneurysms were treated with Enterprise (n = 57) or Solitaire (n = 32) SAC. The patients' demographics, angiographic results, and clinical outcomes were reviewed retrospectively. RESULTS: There were no cases of stent navigation, deployment failure, arterial dissection, or intraoperative aneurysmal rupture. Angiographic follow-up imaging was available for 86 (96.6%) aneurysms (Enterprise group, n = 55; Solitaire group, n = 31). Immediate postoperative and follow-up angiographic results showed no flow or only minimal flow into the neck in 83% (Enterprise group, 77.2%; Solitaire group, 93.8%) and 95.3% (Enterprise group, 92.7%; Solitaire group, 100%) of SAC-treated aneurysms, respectively. Both stent groups showed good immediate postoperative and follow-up clinical outcomes. Excepting 2 cases, all patients achieved modified Rankin Scale scores of 0. Coil loop or tail protrusion into the parent artery was observed in 17 (29.8%) and 7 (21.9%) cases in the Enterprise and Solitaire groups, respectively. No statistically significant difference in terms of angiographic results or clinical outcomes was observed between the groups. CONCLUSION: Excellent and comparable clinical and angiographic outcomes for wide-neck intracranial aneurysms were achieved using both stents. Because of its higher radial strength and better vessel wall apposition, we cautiously propose that the Solitaire stent may be more effective for SAC of aneurysms harboring a large or severe tortuous parent artery.

After acute interruption of cerebral blood flow, various hemodynamic, morphologic and metabolic changes ensue in the occluded area. Such changes and subsequent brain damage are of great concern in the course of temporary arterial occlusion during aneurysmal surgery. Many experimental studies investigating the processes of cerebral infarction have been done through selective occlusion of intracranial vessels, and it has been known that 4 to 8 minutes interruption of cerebral blood flow results in irreversible brain damage. Cerebral resistance following vascular occlusion may be influenced by collateral circulation, hypothermia and hyperventilation. Recently we experienced two patients with right middle cerebral artery aneurysms, who were operated upon under normothermia, slight hypotension, and hyperventilation using microsurgical technique. The technique of temporary occlusion of middle cerebral artery was applied as an adjunctive method.

The familial occurrence of bilateral acoustic neuroma has rarely been reported in the literatures, and its inheritance is known to be an autosomal dominant trait in association with or without von Recklinghausen's disease. Recently, we experienced an unusual case of bilateral acoustic neuroma, which was familially occurred in mother and her son. A 18-year-old Korean boy was referred to us due to bilateral hearing disturbance and staggering gait of one year duration. There were no stigmata of von Recklinghausen's disease. Neurological examination, simple skull films and vertebral angiograms revealed various evidences of bilateral cerebellopontine angle tumors. At operation, a hen egg-sized firm mass was subtotally removed at the left cerebellopontine angle region and a peanut-sized mass was totally removed at the right cerebellopontine angle region via suboccipital craniectomy. The histological diagnosis was neurofibroma. In family history, 13 years ago his mother was operated on C6-7 neurofibroma at her age of 28 years, and again operated on bilateral acoustic tumors 2 years later. The histological diagnosis was also neurofibroma.

A 20-year-old male patient was admitted to this hospital because of headache and high fever on October 10, 1974. He has insidiously develope frontal headache and high fever for these 10 days, followed by vomiting, convulsions, aphasia and motor weakness on the left extremities and subsequently fell into semicomatose state. Hemogram showed marked leukocytosis, 22500/mm3, and cerebrospinal fluid cell count revealed increased leukocyte, 1210/mm3. Simple skull Roentgenograms showed no significant abnormalities except for suspicious haziness on the left frontal sinus. Carotid angiogram showed distal shift of the anterior cerebral artery, medial displacement of the middle cerebral artery and small avascular area on the left temporo-parietal area. Brain scan showed high activities on the entire left cereral hemisphere. On October 12, 1974 a large fronto-temporo-parietal osteoplastic craniotomy was done. Yellowith green, foul odored pus gushed out from the subdural space of the entire operating fields. Preteus mirabilis was isolated in pus culture. He was discharged with good recovery two months later.

Intrasellar or pituitary abscess was first reported about a century ago, after then once relatively common but now is rare. Since 1925, about 50 cases have been reported in the literatures, of which characters were variable, but clinical very similar to one of pituitary tumor. So they were often diagnosed preoperatively as pituitary tumor. Several pathogenic factors were postulated in relation to clinical aspects. We had recently experienced a case of pituitary abscess combined with chromophobe adenoma. A 28 years old clerkman was admitted to our hospital with complaints of impared ejaculation and visual disturbance. Clinical aspects and diagnostic studies gave us a strong impression of pituitary tumor. Upon surgery we found a cystic mass in pituitary region, of which aspiration showed whitish-gray, tenacious and liquid material. Many polymorphous leukocytes were noted by direct smear, but no microorganisms were detected in culture. He had postoperatively suffered from transient polyuria and polydipsia, which soon disappeared under the medication of Esidrex. He was discharged from this hospital with recommendation of radiation therapy. Clinical features and treatment were also discussed with review of ever reported cases.

A number of authors have called attention to the difficulty encountered in diagnosing tumors near the foramen magnum and have formulated symptom complexes in an effort to facilitate early recognition of these lesions. Emphasis has been placed on their bizarre symptoms and on their resemblance to the clinical picture associated with some degenerative diseases of the central nervous system, ruptured cervical disc and cervical spondylosis. Fortunately, it has been known that most of tumors around the foramen magnum are benign, extramedullary and amenable to cure by surgical excision and with minimal morbidity and mortality, provided they are diagnosed early. Recently we experienced a rare case of glioblastoma multiforme at the cervico-medullary junction. A 28-year-old Korean man was admitted to the Dept. of Neurosurgery on May 27, 1974, with 5 months history of cervical and suboccipital pain, and progressive visual disturbance. He had sustained hyperextension injury to his neck 8 months ago, and subsequently developed mild suboccipital and cervical pain which subsided easily with some analgesice. Three months later, he noticed paresthesia and tingling sensation in his upper limbs and anterior chest, especially when he turned his neck to either side. He also had pain in suboccipital region radiating to his both shoulders. Seven months later, he developed sudden paraperesis, poor vision and incoordination with severe suboccipital headache and vomiting. On admission, neurological examination disclosed clear consciousness, bilateral papilledema and abducens nerve palsy and markedly decreased vision. There were clumsiness of movement of both legs, hypesthesia in the face, decreased perception of vibration and position sense below the neck and increased deep tendon reflexes. Fine coordination movements in the upper limbs were disturbed and horizontal hystagmus was also present. Simple skull films showed destruction of the dorsum sellae and the posterior clinoid process, suggesting increased intracranial pressure. Cervical spine films were interpreted as normal. Right carotid angiograms demonstrated marked hydrocephalic patterns, and right vertebral angiograms demonstrated posterior displacement of the tip of the basilar artery and of the choroidal point. Conray ventriculogram showed a sharp filling defect at the level of lateral recess of the fourth ventricle. Suboccipital craniectomy and bilateral laminectomy of the first two cervical vertebrae were performed, disclosing a nodular, meaty, firm mass with some necrosis. The tumor was located posterolateral to the medulla and the spinal cord from the obex to the C2, compressing them and displacing the right cerebellar tonsil upward and laterally. The tumor was removed partially and Torkildsen's shunt was performed. Post-operatively he died suddenly at the end of the second week without any remarkable improvement in symptoms and signs. Pathological report was a glioblastoma multiforme. At autopsy, the tumor was originated from the cervicomedullary junction, extending posteriorly from the obex to the C2 and anteriorly along the brain stem up to the perichiasmatic region.

Fluorescein retinal angography has been used in order to make differential diagnosis between true papilledema and pseudopapilledema, and to make early confirmation of the incipient papilledema. After injection of 5 cc of 10% fluorescein sodium into antecubital vein, the fluorescein retinal angiographic findings of 6 normal adults and 17 papilledematous patients of the brain tumor were obtained by Zeiss fundus camera(exciter filter:Kodak Wratten 47 A, barrier filter:Schott GG 14). 1. The characteristic findings of papilledema in the disc are: a. Leakage of fluorescein from capillaries and persistence of the fluorescence till late stage. b. Capillary dilatation. c. Microaneurysm. 2. The massive leakage of the fluorescen is seen in the patients of the 3 rd ventricular or posterior fossa tumors. 3. The decreased visual acuity is prominent in the patients showing marked capillary dilatation and microaneurysm.
