RESUMEN
OBJECTIVE: The conscious patients with a small amount of acute subdural hematoma had no neurological deterioration are managed conservatively. Most of them are resolved spontaneously in several weeks without surgery. In our experience, however, some progressed to chronic stage requiring surgical treatment in a few days, unlike chronic subdural hematoma derived from acute hematoma following several weeks or months after head trauma. We aimed to analyse this phenomenon and associated the risk factor comparing with the chronic subdural hematomas. METHODS: Retrospective analysis of 175 alert patients with unilateral acute subdural hematoma identified among 661 patients diagnosed the acute subdural hematoma from October 2009 to September 2012 was performed. Univariate and multivariate analyses were performed to describe the relationships between progression to chronic stage requiring surgery from small amount of acute subdural hematoma and clinical characteristics and radiologic features. RESULTS: Eighteen patients (10.3%) showed neurological deterioration due to progression to chronic stage of acute subdural hematoma and underwent a surgical treatment. The mean time interval between the head trauma and development of neurological symptoms was 12.7 days. Univariate and multivariate analyses found that depth of hematoma and degree of brain swelling were a risk factor for progression to chronic stage requiring surgery from the acute subdural hematoma. CONCLUSION: In spite of the conscious patients with acute subdural hematoma not requiring surgical decompression, the more amount of hematoma and the severer brain swelling, there is higher probability of neurological deterioration caused by the progression to chronic stage in a few days.

Gout is a common metabolic disease in which monosodium urate crystals called tophi develop. Spinal involvement in gout resulting in neural compression is unusual. We describe a case of a 64-year-old man with a history of gouty arthritis of the knee. The patient presented with thoracic myelopathy and radiculopathy. Imaging of the spine revealed an extradural mass lesion with bony erosion of the thoracic spine. A decompressive operation was performed, and a chalky white material was found. Histopathological examination confirmed a gouty tophus. The symptoms of spinal gout vary and its radiological features are not sufficiently specific to provide a definite diagnosis. Therefore, in patients with a history of gouty arthritis who present with neural compressive symptoms of the spine, spinal gout should be strongly suspected.

OBJECTIVE: The purpose of this study was to investigate the patterns and the risk factors of newly developed vertebral compression fractures (VCFs) after percutaneous vertebroplasty (PVP). METHODS: We performed a retrospective review of the 244 patients treated with PVP from September 2006 to February 2011. Among these patients, we selected 49 patients with newly developed VCFs following PVP as the new VCFs group, and the remaining 195 patients as the no VCFs group. The new VCFs group was further divided into 2 groups : an adjacent fractures group and a nonadjacent fractures group. The following data were collected from the groups : age, gender, body weight/height, body mass index (BMI), bone mineral density (BMD) score of the spine and femur, level of initial fracture, restoration rate of anterior/middle vertebral height, and intradiscal cement leakage, volume of polymethylmethacrylate (PMMA). RESULTS: Age, gender, mean body height/weight, mean BMI and volume of PMMA of each of the group are not statistically significantly associated with fractures. In comparison between the new VCFs group and the no VCFs group, lower BMD, intradiscal cement leakage and anterior vertebral height restoration were the significant predictive factors of the fracture. In addition, new VCFs occurrence at the adjacent spines was statistically significant, when the initial fracture levels were confined to the thoracolumbar junction, among the subgroups of new VCFs. CONCLUSION: Lower spinal BMD, the greater anterior vertebral height restoration rate and intradiscal cement leakage were confirmed as risk factors for newly formed VCFs after PVP.

Spinal infection is an inflammatory process around the vertebral body, and it can extend to the epidural space, posterior elements and paravertebral soft tissues. Infectious spondylitis is a rare infectious disorder, which is often associated with significant neurologic deficits and mortality. When an extensive soft tissue defect is accompanied by infectious spondylitis, effective infection control and proper coverage of soft tissue are directly connected to successful outcomes. However, it is not simple to choose the appropriate treatment methods for infectious spondylitis accompanied by a soft tissue defect. Herein, we report a case of severe infectious spondylitis that was accompanied by an extensive soft tissue defect which was closed with a reverse latissimus muscle flap after traumatic spinal epidural hemorrhage.

The expanded endonasal approach (EEA) to the ventral skull base provides endoscopic access from the frontal sinus to the second cervical vertebra. Potential advantages of the EEA include not only improved cosmesis but more importantly, the potential for reduced neurovascular manipulation. EEA is based on the principle of extracapsular dissection with full visualization of important neurovascular structures. There are significant risks of neural and vascular injury associated with EEA, and the reconstruction of dural defects is challenging. Experienced teams including rhinologists and neurosurgeons are needed for successful implementation of EEA. The surgical team must have adequate endoscopic skills to achieve hemostasis and address vascular emergencies. Advantages of having a skilled second surgeon to provide endoscopic visualization include dynamic adjustments of the endoscope to ensure the best view and avoid contact interference of instruments, second surgical opinions in complex anatomical areas, and maintenance of endoscopic views in cases of crisis such as vascular injury. Complications of the EEA such as neurovascular injury, cerebrospinal fluid leaks and infection are the same as those of open approaches. With the advent of the nasoseptal flap, problematic cases involving huge bony defects subsequent to the resection of skull base tumors have been greatly resolved.

BACKGROUND AND OBJECTIVES: The aim of this study was to compare endoscopic endonasal transsphenoidal hypophysectomy (EETSA) with microscopic transseptal transsphenoidal hypophysectomy (MTTSA) in terms of clinical results during an acceleration of learning curve. SUBJECTS AND METHOD: A retrospective chart review was performed of the first 14 cases of EETSA and previous 14 cases of MTTSA. Resection results, endocrinologic outcomes, complication rates, operating time, and duration of hospital stay were investigated. A non-parametric analysis was performed to determine the significance of differences between groups. RESULTS: EETSA was performed, achieving gross total removal, based on postoperative MRI, for 12 of the 14 patients (86%) and hormonal remission for 4 of the 5 patients (80%); on the other hand, MTTSA was performed, achieving gross total removal for 9 of the 14 patients (64%) and hormonal remission for 1 of the 5 patients (20%). We found better resection results in patients who underwent EETSA than in those who did MTTSA with respect to tumors extending into suprasellar area (p<0.05). Visual improvement was achieved in all the cases with visual defect (n=5) after EETSA, whereas 4 of 6 cases (66%) were improved after MTTSA. Significant differences in complication rates, operating time and hospital stay could not be determined. All cases with CSF leakage in EETSA were successfully managed by using the nasoseptal flap. CONCLUSION: EETSA provided better resection results than MTTSA did, especially in cases extending into the suprasellar area, showing good hormonal cure and visual improvement rates. Two approaches were comparable with respect to complications during the learning curve.

OBJECTIVE: To report our experience with pyogenic spondylitis treated with anterior radical debridement and insertion of a titanium mesh cage and to demonstrate the effectiveness and safety of the use of a titanium mesh cage in the surgical management of pyogenic spondylitis. METHODS: We retrospectively analyzed the clinical characteristics of 19 patients who underwent surgical treatment in our department between January 2004 and December 2008. The average follow-up period was 11.16 months (range, 6-64 months). We evaluated risk factors, cultured organisms, lab data, clinical outcomes, and radiographic results. Surgical techniques for patients with pyogenic spondylitis were anterior radical debridement and reconstruction with titanium mesh cage insertion and screw fixation. All patients received intravenous antibiotics for at least 6 weeks postoperatively, and some patients received oral antibiotics. RESULTS: The infections resolved in all of the patients as noted by normalization of their erythrocyte sedimentation rates and C-reactive protein levels. The mean pain score on a Visual Analog Scale was 7.8 (range, 4-10) before surgery and 2.4 (range, 1-5) after surgery. The Frankel grade was improved by one grade in seven patients. After surgery, the average difference of the angle was improved about 6.96degrees in all patients. At the last follow-up, the mean loss of correction was 4.86degrees. CONCLUSION: Anterior radical debridement followed by the placement of instrumentation with a titanium mesh cage may be a safe and effective treatment for selected patients with pyogenic spondylitis. This surgical therapy does not lead to recurrent pyogenic spondylitis.

Cerebrospinal fluid (CSF) leakage is a possible major complication in skull base surgery. Application of the expanded endoscopic endonasal approach in skull base surgery expands the accessibility to resect skull base lesions but also increases the risk of CSF leakage due to the creation of larger dural defects in the skull base. Reconstruction of the skull base with multilayered autologous materials has been a key surgical technique. A recent advance in skull base reconstruction is nasoseptal flap, a robust reliable vascular pedicled flap supplied with the septal branch of the sphenopalatine artery. This technique has been reported to significantly decrease the risk of CSF leakage. We report a case of giant pituitary adenoma involving the suprasellar space and sphenoid sinus with a near total sellar defect. The lesion was removed using the endoscopic endonasal transsphenoidal approach, and the sellar floor was successfully reconstructed using a nasoseptal flap with no other multilayered support.

PURPOSE: To compare the dose distributions between three-dimensional (3D) and four-dimensional (4D) radiation treatment plans calculated by Ray-tracing or the Monte Carlo algorithm, and to highlight the difference of dose calculation between two algorithms for lung heterogeneity correction in lung cancers. MATERIALS AND METHODS: Prospectively gated 4D CTs in seven patients were obtained with a Brilliance CT64-Channel scanner along with a respiratory bellows gating device. After 4D treatment planning with the Ray Tracing algorithm in Multiplan 3.5.1, a CyberKnife stereotactic radiotherapy planning system, 3D Ray Tracing, 3D and 4D Monte Carlo dose calculations were performed under the same beam conditions (same number, directions, monitor units of beams). The 3D plan was performed in a primary CT image setting corresponding to middle phase expiration (50%). Relative dose coverage, D95 of gross tumor volume and planning target volume, maximum doses of tumor, and the spinal cord were compared for each plan, taking into consideration the tumor location. RESULTS: According to the Monte Carlo calculations, mean tumor volume coverage of the 4D plans was 4.4% higher than the 3D plans when tumors were located in the lower lobes of the lung, but were 4.6% lower when tumors were located in the upper lobes of the lung. Similarly, the D95 of 4D plans was 4.8% higher than 3D plans when tumors were located in the lower lobes of lung, but was 1.7% lower when tumors were located in the upper lobes of lung. This tendency was also observed at the maximum dose of the spinal cord. Lastly, a 30% reduction in the PTV volume coverage was observed for the Monte Carlo calculation compared with the Ray-tracing calculation. CONCLUSION: 3D and 4D robotic radiotherapy treatment plans for lung cancers were compared according to a dosimetric viewpoint for a tumor and the spinal cord. The difference of tumor dose distributions between 3D and 4D treatment plans was only significant when large tumor movement and deformation was suspected. Therefore, 4D treatment planning is only necessary for large tumor motion and deformation. However, a Monte Carlo calculation is always necessary, independent of tumor motion in the lung.

OBJECTIVE: Traditionally, peritoneal catheter is inserted with midline laparotomy incision in ventriculoperitoneal (V-P) shunt procedures. Complications of V-P shunt is not uncommon and have been reported to occur in 5-37% of cases. The aim of this study is to compare the clinical outcomes and the operation time between laparotomy and laparoscopic groups. METHODS: A total of 155 V-P shunt procedures were performed to treat hydrocephalic patients of various origins in our institute between June 2006 to January 2010; 95 of which were laparoscopically guided and 65 were not. We reviewed the operation time, surgery-related complications, and intraoperative and postoperative problems. RESULTS: In the laparoscopy group, the mean duration of the procedure (52 minutes) was significantly shorter (p < 0.001) than the laparotomy group (109 minutes). There were two cases of malfunctions and one incidence of diaphragm injury in the laparotomy group. In contrast, there were neither malfunction nor any internal organ injuries in the laparoscopy group (p = 0.034). There were total of two cases of infections from both groups (p = 0.7). CONCLUSION: Laparoscopically guided insertions of distal shunt catheter is considered a fast and safe method in contrast to the laparotomy technique. This method allows the exact localization of the peritoneal catheter and a confirmation of its patency.

We present a case of posterior atlantoaxial screw-rod fixation in a patient with an aberrant vertebral artery (VA) course combined with bilateral high-riding VA. An aberrant VA which courses below the posterior arch of the atlas (C1) that does not pass through the C1 transverse foramen and without an osseous anomaly is rare. However, it is important to consider an abnormal course of the VA both preoperatively and intraoperatively in order to avoid critical vascular injuries in procedures which require exposure or control of the VA, such as the far-lateral approach and spinal operations.

OBJECTIVE: The aim of this study was to evaluate the consistency between revised prognostic score derived from the Tokuhashi scoring system(TSS) and the actual patient survival period after surgical treatment at our institution. METHODS: From 1998 to 2005, surgically treated 44 patients with metastatic spine tumors were reviewed retrospectively at our institution. Among these 44 patients, 32 had died, 2 were alive at the time of the last follow-up evaluation, and 10 were lost to the follow-up. Only 32 patients who died after surgery have been investigated in this study. Preoperatively, patients were staged serveral standard diagnostic modalities, such as, plain radiographs, computed tomography, magnetic resonance imaging and etc. Each patient was evaluated using the TSS and placed in one of three groups depending upon this evaluation. RESULTS: The actual mean(+/-SD) survival period was 6.6 months(+/-1.14) for the first group (predicted survival periods in revised TSS, less than 6 months), 15.1 months(+/- 5.38) for the second group(predicted survival periods in revised TSS, 6 months or more) and 37.5 months(+/-8.70) for the third group(predictied survival period in revised TSS, 1 year or more). The survival periods for these groups were significantly different(p=0.0006). Applying the TSS for evaluation of prognosis of metastatic spinal tumors was found to be very reliable results with a statistically significance. Of six parameters measured in the TSS, Extraspinal bone metastases, metastases to the major internal organs, the primary tumor site contributed to predicting the survival periods. CONCLUSIONS: This study has revealed that the revised prognostic score resulting from the TSS predicts actual survival periods remarkably well. Hence, we thought that the revised TSS could be useful and reliable tool in prognosis of metastic spinal tumors.

OBJECT: The aim of this study is to analyze the statistical significance between the clinical result and subsidence and lordosis loss after anterior cervical discectomy and interbody fusion operation for degenerative cervical disc diseases. METHODS: From January 2004 to December 2006, retrospective study of 82 patients with symptomatic degenerative cervical disc disease who underwent anterior cervical discectomy and interbody fusion using the PEEK SolisTM cage and the carbon composite Osta-PekTM cage with autologous bone graft was done. Mean follow-up period was 13.2 months. Clinical results were assessed by bone fusion, subsidence, segmental lordosis loss and Odom's criteria. RESULTS: Of the 82 patients, single level fusion was accomplished in 67 patients and two-level fusion in 15 patients. Total accomplished fusion level was 97: C3/4 in 9 levels, C4/5 in 29 levels, C5/6 in 37 levels, C6/7 in 21 levels, C7/T1 in 1 level. 9 patients fit into complete resolved, 59 improved and 14 not changed, thus the success rate in clinical outcome was 82.9%. Bone fusion was successfully confirmed in the total of 82 patients. The height of disc space was decreased to 2.13+/-2.16mm: 2.64+/-1.81mm in the Osta-PekTM cage, 2.44+/-1.36mm in the PEEK SolisTM cage. The Osta-PekTM cage provided higher subsidence tendency than the PEEK SolisTM cage in our study. However, there was no statistical significance between the two cage groups. The subsidence and lordosis loss showed poor clinical outcome, but there was no statistical significance. CONCLUSIONS: There were no significant differences between the Osta-PekTM cage and PEEK SolisTM cage on clinical outco mes. Both cages showed low subsidences and lordosis loss with good fusion rate and clinical outcome.

OBJECTIVE: Cerebral vasospasm leading to cerebral ischemic infarction is a major cause of morbidity and mortality in the patients who suffer with aneurysmal subarachnoid hemorrhage. Despite adequate treatment, some patients deteriorate and they develop symptomatic vasospasm. The objective of the present study was to investigate the efficacy and clinical outcome of intraarterial nimodipine infusion on symptomatic vasospasm that is refractory to hemodynamic therapy. METHODS: We retrospectively reviewed the procedure reports, the clinical charts and the transcranial doppler, computed tomography and digital subtraction angiography results for the patients who underwent endovascular treatment for symptomatic cerebral vasospasm due to aneurysmal SAH. During the 36 months between Jan. 2005 and Dec. 2007, 19 patients were identified who had undergone a total of 53 procedures. We assessed the difference in the arterial vessel diameter, the blood flow velocity and the clinical outcome before and after these procedures. RESULTS: Vascular dilatation was observed in 42 of 53 procedures. The velocities of the affected vessels before and after procedures were available in 33 of 53 procedures. Twenty-nine procedures exhibited a mean decrease of 84.1 cm/s. We observed clinical improvement and an improved level of consciousness with an improved GCS score after 23 procedures. CONCLUSION: Based on our results, the use of intraarterial nimodipine is effective and safe in selected cases of vasospasm following aneurysmal SAH. Prospective, randomized studies are needed to confirm these results.

OBJECTIVE: The authors present their experiences with stereotactic multiplanar reformatted (MPR) computed tomography (CT)-guided catheter placement for thrombolysis of spontaneous intracerebral hematoma (sICH) and their clinical results. METHODS: In 23 patients with sICH, MPR CT-guided catheter placement was used to select the trajectory and target point of hematoma drainage. This group was comprised of 11 men and 12 women, and the mean age was 57.5 years (range, 31-79 years). The patients' initial Glasgow Coma Scale scores ranged from 7 to 15 with a median of 11. The volume of the hematoma ranged from 24 mL to 86 mL (mean 44.5 mL). A trajectory along the main axis of the hematoma was considered to be optimal for thrombolytic therapy. The trajectory was calculated from the point of entry through the target point of the hematoma using reformatted images. RESULTS: The hematoma catheter was left in place for a median duration of 48.9 hours (range 34 to 62 hours). In an average of two days, the average residual hematoma volume was 6.2 mL (range 1.4 mL to 10.2 mL) and was reduced by an average of 84.7% (range 71.6% to 96.3%). The residual hematoma at postoperative seven days was less than 5 mL in all patients. There was no treatment-related death during hospitalization. CONCLUSION: The present study indicates that stereotactic MPR CT-guided catheter placement for thrombolysis is an accurate and safe procedure. We suggest that this procedure for stereotactic removal of sICH should be considered for the optimization of the trajectory selection in the future.

OBJECTIVE: Numerous studies have compared the characteristics of familial intracranial aneurysms with those of non-familial aneurysms. To better understand familial subarachnoid hemorrhage (SAH), we studied a series of patients with SAH who had at least one first-degree relative with SAH, and compared our results with those of previous studies. METHODS: We identified patients treated for SAH at our hospital between January 1993 and October 2006 and analyzed those patients with one or more first-degree relatives with SAH. We retrospectively collected data from patients with a family history and searched for patients who had relatives with aneurysms or who had been treated at other hospitals for SAH. RESULTS: We identified 12 patients from six families with at least two first-degree relatives with SAH. All patients had affected first-degree relatives; in five families, they were siblings. The mean age at the time of rupture was 49.75 years; in four families, the age difference was within 5 years. In five patients (42%), the aneurysm was located in the middle cerebral artery. Only one patient had an aneurysm in the anterior communicating artery. CONCLUSION: In agreement with previous studies, our results showed that familial aneurysms, in comparison with non-familiar aneurysms, ruptured at a younger age and smaller size, had a high incidence in the middle cerebral artery, and were underrepresented in the anterior communicating artery. Interestingly, the age at the time of rupture was similar between relatives. Screening should be considered in the fifth or sixth decade for those who have a sibling with SAH.

OBJECTIVE: The purpose of the study was to determine the clinical effects of anterior radical debridement on a series of patients with spontaneous spinal infection. METHODS: We retrospectively analyzed the clinical characteristics of 32 patients who underwent surgical treatment from January 2000 to December 2005 in our department. The average follow-up Period was 33.4 months (range, 6 to 87 months). Thirty-two patients presented with the following : 23 cases with pyogenic spondylitis, eight with tuberculous spondylitis and one with fungal spondylitis. The indications for surgery were intractable pain, failure of medical management, neurological impairment with or without an associated abscess, vertebral destruction causing spinal instability and/or segmental kyphosis. RESULTS: The study included 15 (46.9%) males and 17 (53.1%) females ranging in age from 26 to 75 years (mean, 53.1 years). Diabetes mellitus (DM) and pulmonary Tbc were the most common predisposing factors for pyogenic spondylitis and tuberculous spondylitis. Staphylococcus aureus (13%) was the main organism isolated. The most prevalent location was the lumbar spine (75%). Changes in the pain score, Frankel's classification, and laboratory parameters demonstrated a significant clinical improvement in all patients. However, there were recurrent infections in two patients with tuberculous spondylitis and inappropriate debridement and intolerance of medication and noncompliance. Autologous rib, iliac bone and allograft (fibular) were performed in most patients. However, 10 patients were grafted using a titanium mesh cage after anterior radical debridement. There were no recurrent infections in the 10 cases using the mesh cage with radical debridement. CONCLUSION: The findings of this study indicate that surgery based on appropriate surgical indications is effective for the control of spinal infection and prevention of recurrence with anterior radical debridement, proper drug use and abscess drainage.
