With the development of devices and techniques, including complex shape coils, balloons, multiple catheter techniques, and intracranial stents, endosaccular treatment of ruptured or unruptured wide-necked cerebral aneurysms has advanced rapidly with respect to indications and outcomes. In contrast to other options, stent-assisted aneurysm embolization has a distinct feature in which the stent is permanently implanted in the cerebral vessels. Therefore, we must consider the short-term effect of stent-assisted aneurysm embolization in the prevention of coil migration and adverse thrombogenicity, but also the permanent mechanical, hemodynamic, and biological influence on the parent vessels and the aneurysm. We have reviewed the current experimental and clinical data on stent-assisted coil embolization of cerebral aneurysms.

The incidence of distal anterior cerebral artery(ACA) aneurysm is relatively rare, and only a few cases of bilateral symmetrical distal ACA aneurysms which were adhered together have been reported. They are also called kissing aneurysms. We treated bilateral symmetrical distal ACA kissing aneurysms in a 44-year-old woman. We successfully clipped the double aneurysmal sacs individually by interhemispheric approach in spite of intraoperative aneurysmal rupture. The patient was discharged without any neurological deficits two weeks after the operation.

Background: and Purpose: Neural stem cells (NSCs) have the ability to regenerate, proliferate, and differentiate, enabling them to play important roles in the recovery of the damaged nervous system. However, in neurodegenerative diseases such as Alzheimer's disease (AD), the NSCs are damaged as well. Glia-like cells from human mesenchymal stem cells (ghMSCs) are functionally enhanced adult stem cells. In the present study, we investigated whether ghMSCs could protect NSCs from amyloid beta (Aβ)-mediated toxicity. Methods: Rat NSCs were obtained from E13–14 fetal rat cortices. NSCs were seeded in pre-coated plates, and the next day, cells were simultaneously treated with 20 μM Aβ and 0.4 μm pore insert well-seeded ghMSCs. After 48 hours of co-treatment, cell viability and proliferation were evaluated. After 2 hours of co-treatment, western blotting was performed to measure inflammasome-related factors, such as NOD-like receptor family pyrin domain containing 3, caspase-1, and interleukin-1β. Results: The results showed that ghMSCs increased viability and proliferation and reduced the toxicity of NSCs injured by Aβ by reducing the NRLP3 inflammasome activation of NSCs induced by Aβ. Conclusions In this study, we confirmed that ghMSCs could protect NSCs in an in vitro model of AD through the regulation of inflammatory response.

Primary oligodendroglioma of the spinal cord is very rare tumor. On searching through the literature from 1931, we could find only about 46 cases, and this tumor is almost absent in Korea on the review of the literature. The authors present a case of 8-year-old female patient with the symptoms of paraparesis, urination difficulty, diffuse back pain and hypesthesia in both lower extremities. Spine MRI revealed the mass at the level of T3-T12, with combined nature of cystic and solid portion. Decompressive laminectomy and partial mass removal was performed, and then adjunctive radiotherapy and chemotherapy was done. The patient was improved after operation with radiotherapy and chemotherapy, so she walks alone and has no voiding difficulty at present(postoperative about 20 months) .

Seventy-nine children and 433 adults were treated for epidural hematoma at our hospital during the last 10 years. The authors have tried to compare the various clinical characteristics and significant prognostic factors of epidural hematoma in children and adults. The result confirmed that children with traumatic epidural hematoma are less likely to have direct relationship with various causes of head trauma, associated extracranial injuries, skull fractures, temporal region hematomas, and immediate surgeries, but tend to have high preoperative GCS scores, prompt pupil responses, require only conservative treatments, have short durations of coma, and have good outcome. The cause of injury, amount of hematoma and focus of bleeding on surgery are found to be significant prognostic factors in adults, but are not in children. In cases with same scores of preoperative Glasgow Coma Scale(GCS) and durations of coma, very severe neurologic status(below 7 of GCS, both dilated fixed pupil) had a worse outcome in children as well as in adults without significant difference between them. The clinical index on preoperative GCS and pupillary response used when deciding the operation time were different in children compared to adults. Operations performed in delayed fashion in children under close observation for changes in GCS and pupillary response showed good outcome. However, adults require operations as early as possible because of possible rapid progression.

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%.

One hundreds eighty cases of traumatic intracerebral hematoma(TICH) among 1,633 head injury patients diagnosed with computerized tomography in neurosurgical department from Jan. 1990 to Jun. 1996. were classified into two TICH groups; TICH group associated with other traumatic intracranial lesions and TICH group without other traumatic intracranial lesions. The incidence of TICH was 11.0% and percentage of TICH with other traumatic intracranial lesions among 180 cases of TICH was 66.7%. TICH group with other traumatic intracranial lesions showed worse initial level of consciousness, more likely to have abnormal pupillary reflex, higher incidence of delayed traumatic intracerebral hematomas(DTICH), greater amount of hematoma, increased chance of surgery and worse outcome. In TICH group with other traumatic intracranial lesions, the factors affecting prognosis were initial Glasgow coma scale(GCS) score, pupillary reflex, amount of hematoma and treatment modality. In TICH only group, the factors affecting prognosis were initial GCS score, pupillary reflex, amount of hematoma and DTICH. The patients with 12-15 of GCS score, normal pupillary reflex, absence of DTICH, and amount of hematoma below 10cc, the presence of other traumatic intracranial lesions were found to be important prognostic factor. The overall mortality was 27.7% but in TICH group with other traumatic intracranial lesions, the mortality was 35.0% compared to 13.3% in TICH only group. It is concluded from this study that in the case with other traumatic intracranial lesions, TICH showed worse initial neurological status and prognosis compared to those without other lesions. Thus, these patients, although in conditions of good general clinical index at admission, should be considered to provide intensive care and treatment because these associated lesions will play as a bad prognostic factor.

Hemorrhage due to capillary telangiectasia is rare. We report a case of capillary telangiectasia presenting with repeated cerebellar hemorrhage in a 38-year-old male. To our knowledge this is the first case of repeated cerebellar hemorrhage from the capillary telangiectasia. At the first operation, we removed hematoma only, but rebleeding occurred repeatedly in the same area. Finally, we evacuated the recurrent hematoma and vascular mass of capillary telangiectasia at the second operation under surgical microscope. Based on the findings of this case and a review of the literature, we conclude that capillary telangiectasia can be the cause of the massive repeated hemorrhage.
