RESUMO
A variety of complications in endoscopic third ventriculostomy have been reported, including neurovascular injury, hemodynamic alterations, endocrinologic abnormalities, electrolyte imbalances, cerebrospinal fluid leakage, fever and infection. Even though most complications are transient, the overall rate of permanent morbidity is 2.38% and the overall mortality rate is 0.28%. To avoid these serious complications, we should keep in mind potential complications and how to prevent them. Proper decisions with regard to surgical indication, choice of endoscopic entry and trajectory, careful endoscopic procedures with anatomic orientation, bleeding control and tight closure are emphasized for the prevention of complications.

BACKGROUND: The purpose of this study was to evaluate the prognostic factors and outcomes in patients with ependymoma to management plans. METHODS: Between 1997 and 2013, 33 patients with 25 ependymomas (WHO grade II) and eight anaplastic ependymomas (WHO grade III) were pathologically diagnosed. Six were pediatric patients (mean age, 6.15 years; range, 1.3–11 years), while 27 were adults (mean age, 47.5 years; range, 19–70 years). Of those, there were 12 adult patients with totally resected ependymomas without anaplastic pathology and adjuvant treatment. Prognostic factors were assessed in ependymoma patients. Prognostic factors were studied using Kaplan-Meier estimates in subgroups. RESULTS: For six pediatric patients, the progression-free survival (PFS) was 43.7±13.5 months, and the overall survival (OS) was 58.1±13.7 months. For 27 adult patients, the PFS was 125.6±14.3 months, and the OS was 151.2±12.5 months. Age demonstrated a statistically significant effect on PFS (p=0.03) and OS (p=0.03). In adult ependymomas, the extent of tumor removal significantly affected PFS (p=0.03) and trended towards an effect on OS (p=0.06). Out of 12 patients with totally resected ependymomas without anaplastic pathology and adjuvant treatment, one patient showed tumor recurrence during follow-up (mean, 93.5 months; range, 27.9–162.7 months). CONCLUSION: Adult patients with ependymomas were found to have better survival rates compared to pediatric patients. We suggest that totally resected adult ependymomas without anaplastic pathology could be observed without any adjuvant treatment, regardless of the tumor location.

OBJECTIVE: The importance of traumatic dural venous sinus injury lies in the probability of massive blood loss at the time of trauma or emergency operation resulting in a high mortality rate during the perioperative period. We considered the appropriate methods of treatment that are most essential in the overall management of traumatic dural venous sinus injuries. METHODS: We conducted a retrospective review of all cases involving patients with dural venous sinus injury who presented to our hospital between January 1999 and December 2014. RESULTS: Between January 1999 and December 2014, 20 patients with a dural venous sinus injury out of the 1,200 patients with severe head injuries who had been operated upon in our clinic were reviewed retrospectively. There were 17 male and 3 female patients. In 11 out of the 13 patients with a linear skull fracture crossing the dural venous sinus, massive blood loss from the injured sinus wall could be controlled by simple digital pressure using Gelfoam. All 5 patients with a linear skull fracture parallel to the sinus over the venous sinus developed massive sinus bleeding that could not be controlled by simple digital pressure. CONCLUSION: When there is a linear skull fracture parallel to the sinus over the dural venous sinus or a depressed skull fracture penetrating the sinus, the surgeon should be prepared for the possibility of potentially fatal venous sinus injury, even in the absence of a hematoma.

Dens fractures are a common traumatic cervical spine injury. Among them, a type III fracture is the second common fracture. Although there are several treatment options, it has been accepted that type III fracture is usually healed by non-surgical method. After adequate reduction with traction, subsequent external immobilization has been associated with successful union rates. However, in the review of literatures, there are some cases with neurological deterioration after application of skull traction. So, the authors report a case of type III dens fracture with initially unrecognized ligamentous injury in which vertical dissociation and quadriplegia occurred after only five-pound Gardner-Well tongs traction. And also, the authors raise awareness of this potentially injury.

OBJECTIVE: The technique of short segment pedicle screw fixation (SSPSF) has been widely used for stabilization in thoracolumbar burst fractures (TLBFs), but some studies reported high rate of kyphosis recurrence or hardware failure. This study was to evaluate the results of SSPSF including fractured level and to find the risk factors concerned with the kyphosis recurrence in TLBFs. METHODS: This study included 42 patients, including 25 males and 17 females, who underwent SSPSF for stabilization of TLBFs between January 2003 and December 2010. For radiologic assessments, Cobb angle (CA), vertebral wedge angle (VWA), vertebral body compression ratio (VBCR), and difference between VWA and Cobb angle (DbVC) were measured. The relationships between kyphosis recurrence and radiologic parameters or demographic features were investigated. Frankel classification and low back outcome score (LBOS) were used for assessment of clinical outcomes. RESULTS: The mean follow-up period was 38.6 months. CA, VWA, and VBCR were improved after SSPSF, and these parameters were well maintained at the final follow-up with minimal degree of correction loss. Kyphosis recurrence showed a significant increase in patients with Denis burst type A, load-sharing classification (LSC) score >6 or DbVC >6 (p6, or DbVC >6.

OBJECTIVE: Water-tight closure of the dura in extracranial-intracranial (EC-IC) bypass is impossible because the superficial temporal artery (STA) must run through the dural defect. Consequently, subdural hygroma and subcutaneous cerebrospinal fluid (CSF) collection frequently occur postoperatively. To reduce these complications, we prospectively performed suturing of the arachnoid membrane after STA-middle cerebral artery (STA-MCA) and evaluated the clinical usefulness. MATERIALS AND METHODS: Between Mar. 2005 and Oct. 2010, extracranial-intracranial arterial bypass (EIAB) with/without encephalo-myo-synangiosis was performed in 88 cases (male : female = 53 : 35). As a control group, 51 patients (57 sides) underwent conventional bypass surgery without closure of the arachnoid membrane. Postoperative computed tomography (CT) scan was performed twice in three days and seven days later, respectively, for evaluation of the presence of subdural fluid collection and other mass lesions. RESULTS: The surgical result was excellent, with no newly developing ischemic event until recent follow-up. The additional time needed for arachnoid suture was five to ten minutes, when three to eight sutures were required. Post-operative subdural fluid collection was not seen on follow-up computed tomography scans in all patients. CONCLUSION: Arachnoid suturing is simple, safe, and effective for prevention of subdural fluid collection in EC-IC bypass surgery, especially the vulnerable ischemic hemisphere.

OBJECTIVE: Neuroendoscopy is applied to various intracranial pathologic conditions. But this technique needs informations for the anatomy, critically. Neuronavigation makes the operation more safe, exact and lesser invasive procedures. But classical neuronavigation systems with rigid pinning fixations were difficult to apply to pediatric populations because of their thin and immature skull. Electromagnetic neuronavigation has used in the very young patients because it does not need rigid pinning fixations. The usefulness of electromagnetic neuronavigation is described through our experiences of neuroendoscopy for pediatric groups and reviews for several literatures. METHODS: Between January 2007 and July 2011, nine pediatric patients were managed with endoscopic surgery using electromagnetic neuronavigation (AxiEM, Medtronics, USA). The patients were 4.0 years of mean age (4 months-12 years) and consisted of 8 boys and 1 girl. Totally, 11 endoscopic procedures were performed. The cases involving surgical outcomes were reviewed. RESULTS: The goal of surgery was achieved successfully at the time of surgery, as confirmed by postoperative imaging. In 2 patients, each patient underwent re-operations due to the aggravation of the previous lesion. And one had transient mild third nerve palsy due to intraoperative manipulation and the others had no surgery related complication. CONCLUSION: By using electromagnetic neuronavigation, neuroendoscopy was found to be a safe and effective technique. In conclusion, electromagnetic neuronavigation is a useful adjunct to neuroendoscopy in very young pediatric patients and an alternative to classical optical neuronavigation.

OBJECTIVE: Recently, microscope-integrated near infrared indocyanine green videoangiography (ICG-VA) has been widely used in cerebrovascular surgery because it provides real-time high resolution images. In our study, we evaluate the efficacy of intraoperative ICG-VA during cerebrovascular surgery. METHODS: Between August 2011 and April 2012, 188 patients with cerebrovascular disease were surgically treated in our institution. We used ICG-VA in that operations with half of recommended dose (0.2 to 0.3 mg/kg). Postoperative digital subtraction angiography and computed tomography angiography was used to confirm anatomical results. RESULTS: Intraoperative ICG-VA demonstrated fully occluded aneurysm sack, no neck remnant, and without vessel compromise in 119 cases (93.7%) of 127 aneurysms. Eight clipping (6.3%) of 127 operations were identified as an incomplete aneurysm occlusion or compromising vessel after ICG-VA. In 41 (97.6%) of 42 patients after carotid endarterectomy, the results were the same as that of postoperative angiography with good patency. One case (5.9%) of 17 bypass surgeries was identified as a nonfunctioning anastomosis after ICG-VA, which could be revised successfully. In the two patients of arteriovenous malformation, ICG-VA was useful for find the superficial nature of the feeding arteries and draining veins. CONCLUSION: ICG-VA is simple and provides real-time information of the patency of vessels including very small perforators within the field of the microscope and has a lower rate of adverse reactions. However, ICG-VA is not a perfect method, and so a combination of monitoring tools assures the quality of cerebrovascular surgery.

OBJECTIVE: Posttraumatic cerebral infarction (PTCI), an infarction in well-defined arterial distributions after head trauma, is a known complication in patients with severe head trauma. The primary aims of this study were to evaluate the clinical and radiographic characteristics of PTCI, and to assess the effect on outcome of decompressive hemicraniectomy (DHC) in patients with PTCI. METHODS: We present a retrospective analysis of 20 patients with PTCI who were treated between January 2003 and August 2005. Twelve patients among them showed malignant PTCI, which is defined as PTCI including the territory of Middle Cerebral Artery (MCA). Medical records and radiologic imaging studies of patients were reviewed. RESULTS: Infarction of posterior cerebral artery distribution was the most common site of PTCI. Fourteen patients underwent DHC an average of 16 hours after trauma. The overall mortality rate was 75%. Glasgow outcome scale (GOS) of survivors showed that one patient was remained in a persistent vegetative state, two patients were severely disabled and only two patients were moderately disabled at the time of discharge. Despite aggressive treatments, all patients with malignant PTCI had died. Malignant PTCI was the indicator of poor clinical outcome. Furthermore, Glasgow coma scale (GCS) at the admission was the most valuable prognostic factor. Significant correlation was observed between a GCS less than 5 on admission and high mortality (p<0.05). CONCLUSION: In patients who developed non-malignant PTCI and GCS higher than 5 after head injury, early DHC and duroplasty should be considered, before occurrence of irreversible ischemic brain damage. High mortality rate was observed in patients with malignant PTCI or PTCI with a GCS of 3-5 at the admission. A large prospective randomized controlled study will be required to justify for aggressive treatments including DHC and medical treatment in these patients.

CONCLUSION: Vascular reconstruction is an important part of the treatment of complex intracranial aneurysms. We report our clinical experience using vascular reconstruction techniques without an extracranial arterial stump for the treatment of complex intracranial aneurysms. METHODS: We conducted a retrospective review of five patients who underwent in situ bypasses and two patients who underwent direct neck suture secondary to clip reinforcement for the treatment of complex intracranial aneurysms between January 1999 and May 2008. RESULTS: Five of the aneurysms were fusiform and the other two were blood blister-like aneurysms (BBAs). Fusiform aneurysms were located at the anterior cerebral artery (ACA) in two patients and the middle cerebral artery (MCA) in three patients. The aneurysms were treated with end-to-side anastomosis after aneurysm excision in three cases and end-to-end anastomosis after aneurysm excision in two cases. Two cases of BBA on the dorsal intracranial artery (ICA) wall were treated by direct suture secondary to the wrapping-clipping method. Follow-up angiography was performed in five patients and revealed patent bypasses in four patients. Follow-up angiography was not performed in two patients due to their poor postoperative condition, and it revealed delayed occlusion due to granuloma formation in one patient with BBA. The patient outcomes were excellent in five patients and poor in two patients whose clinical condition was Hunt- Hess grade V preoperatively. CONCLUSION: In situ bypass is an effective alternative to extracranial-intracranial bypass for distally located fusiform aneurysms. In addition, arterial suturing followed by the wrapping-clipping method is a useful technique for fragile aneurysms unamenable to direct clip or encircled clip for true ICA trunk aneurysms. Although technically challenging, this technique of vascular reconstruction without extracranial arterial graft should be considered for appropriate candidates.

OBJECTIVE: Distal middle cerebral artery (MCA) aneurysms are the least frequent aneurysms of the MCA, and they represent about 1.1 to 5% of all MCA aneurysms. Patients with ruptured distal MCA aneurysms generally have a poor clinical outcome. The purpose of this article is to review the characteristics of distal MCA aneurysms to avoid the complications of microsurgical dissection and clipping of distal MCA aneurysms. METHODS: A total of 1187 patients with ruptured aneurysms were treated at our hospital between January 1997 and May 2008. All patients underwent surgical procedures. Computed tomography (CT) revealed rupture of distal MCA aneurysms in 15 (1.26%) patients. The location of the aneurysm were the M2 (insular) segment in seven patients, the M2-3 junction in three and the M3 (opercular) segment in five. Brain CT images revealed the presence of both subarachnoid hemorrhage (SAH) and intracranial hemorrhage (ICH) in 11 of 15 (77.3%) patients, with a mean ICH volume of 14.5 cc (range : 5 to 32 cc). Rebleeding occurred in 7 out of the 15 (46.7%) patients. RESULTS: All the patients underwent early surgical procedures, including clipping in seven, trapping in two, bypass surgery in four, Guglielmi detachable coil embolization in one and exploratory craniotomy in one patient. The aneurysm had a fusiform appearance in 9 out of 15 cases (60%), and the mean size of the aneurysm was 10.4 mm (range : 2 to 35 mm). Three patients died due to severe brain swelling (20%). CONCLUSION: In this study, distal MCA aneurysms had a relatively fusiform shape as well as high rates of rebleeding and ICH. A good clinical outcome was associated with early surgery for adequately controlling brain swelling and preventing rebleeding.

OBJECTIVE: Ossification of the ligamentum flavum (OLF) is a rare cause of thoracic myelopathy. The aim of this study was to identify factors associated with the surgical outcome on the basis of preoperative clinical and radiological findings. METHODS: Data obtained in 26 patients whot underwent posterior decompression for thoracic myelopathy, caused by thoracic OLF, were analyzed retrospectively. Patient age, duration of symptoms, OLF type, preoperative and postoperative neurological status using the Japanese Orthopedic Association (JOA) scoring system, surgical outcome, and other factors were reviewed. We compared the various factors and postoperative prognosis. All patients had undergone decompressive laminectomy and excision of the OLF. RESULTS: Using the JOA score, the functional improvement was excellent in 8 patients, good in 14, fair in 2, and unchanged in 2. A mean preoperative JOA score of 6.65 improved to 8.17 after an average of 27.3 months. According to our analysis, age, gender, duration of symptoms, the involved spinal level, coexisting spinal disorders, associated trauma, intramedullary signal change, and dural adhesions were not related to the surgical outcome. However, the preoperative JOA score and type of OLF were the most important predictors of the surgical outcome. CONCLUSION: Early diagnosis and sufficient surgical decompression could improve the functional prognosis for thoracic OLF. The postoperative results were found to be significantly associated with the preoperative severity of myelopathy and type of OLF.

OBJECTIVE: Burr hole drainage has been widely used to treat chronic subdural hematoma (CSDH). However, the incidence of recurrent CSDH varies from 3.7 to 30% after surgery. The authors attempted to elucidate the risk factors associated with the recurrence of CSDH in one burr hole drainage technique. METHODS: A total of 255 consecutive cases who underwent one burr hole drainage for CSDH were included in this study. Twenty-four patients (9.4%) underwent a repeated operation because of the recurrence of CSDH. We analyzed retrospectively the demographic, clinical and radiologic factors associated with the recurrence of CSDH. RESULTS: In this study, two risk factors were found to be independently associated with the recurrence of CSDH. The incidence of CSDH recurrence in the high- and mixed-density groups was significantly higher than those in the low- and iso-density groups (p<0.001). Bleeding tendency such as in leukemia, liver disease and chronic renal failure was also significantly associated with recurrence of CSDH (p=0.037). CONCLUSION: These results suggest that high- and mixed-density shown on computed tomographic scan was closely relates with a high incidence of recurrence. Therefore, the operation could be delayed in those cases unless severe symptoms or signs are present. Reoperation using the previous burr hole site is a preferred modality to treat the recurrent CSDH.

OBJECTIVE: Posterior arthrodesis in atlantoaxial instability has been performed using various posterior C1-2 wiring techniques. Recently, transarticular screw fixation (TASF) technique was introduced to achieve significant immediate stability of the C1-2 joint complex. The purpose of this study is to assess the clinical outcomes associated with posterior C1-2 TASF for the patient of atlantoaxial instability. METHODS: We retrospectively reviewed data obtained from 17 patients who underwent C1-2 TASF and supplemented Posterior wiring technique (PWT) with graft between 1994 and 2005. There were 8 men and 9 women with a mean age of 43.5 years (range, 12-65 years). An average follow-up was 26 months (range, 15-108 months). RESULTS: Successful fusions were achieved in 16 of 17 (94%). The pain was improved markedly (3 patients) or resolved completely (14 patients). There was no case of neurological deterioration, hypoglossal nerve injury, or vertebral artery injury. Progression of spinal deformity, screw pullout or breakage, and neurological or vascular complications did not occur. CONCLUSION: The C1-2 TASF with supplemental wiring provided a high fusion rate. Our result demonstrates that C1-2 TASF supplemented by PWT is a safe and effective procedure for atlantoaxial instability. Preoperative evaluation and planning is mandatory for optimal safety.

OBJECTIVE: Pituitary apoplexy, resulting from an acute infarction or hemorrhage mainly in pituitary adenomas, is a rare yet major clinical event with neurological, ophthalmological and hormonal emergent consequences. The authors review our surgical experience with a series of 16 cases of pituitary apoplexy. METHODS: The cases of pituitary apoplexy, operated via trans-sphenoidal approach in our hospital between 1998-2005, were retrospectively analyzed in terms of their clinicoradiological features, pathological findings and surgical outcomes. RESULTS: The mean age of patients (9 male and 7 female) was 47.1 years. The average time of presentation after onset of symptom was 8.9 days. Pituitary apoplexy occurred as an initial manifestation of pituitary adenoma in all patients. Headache was the most common presenting symptom (94%). Visual disturbance was found in 56% of patients. Thirty-one percent of the patients had hypopituitarism. On magnetic resonance imaging, this entire catastrophic event accompanied with macroadenoma in a mean size of 22.5 mm. Only four patients needed postoperative hormone replacement therapy. Three of them showed preoperative hypopituitary function, and one patient in normal pituitary function. There was no specific complication in any of these patients. CONCLUSION: Early trans-sphenoidal decompression with high-dose corticosteroid replacement showed good outcomes of pituitary apoplexy.

OBJECTIVE: Civilian gunshot injuries to the brain are relatively rare and study of these injuries has been neglected in South Korea. We present our experience with penetrating gunshot injuries to the brain and review the outcome of surgical management, as well as other clinical predictors influencing the prognosis. METHODS: We present a retrospective analysis of 13 patients with penetrating gunshot injuries to the brain who were treated at our hospital over a period of 22 years. RESULTS: The Glasgow Coma Scale(GCS) score on admission was recorded to be : 3-5 in 1 patient, 6-8 in 3 patients, 9-12 in 2 patients and 13-15 in 7 patients. There were 11 patients who underwent surgical treatment, and the surgical mortality rate was 0%. The admission GCS score was the most valuable prognostic factor. The best results were found to be in patients admitted with an initial GCS higher than 13. There were no favorable outcomes in patients admitted with a GCS of 8 or lower. There was a correlation between the presence of a transventricular or bihemispheric trajectory and poor outcome. The patients admitted with unilobar wounds resulted in better outcome than those with bilobar or multilobar wounds. Retained deep intracranial bone or metal fragments were the most common postoperative complication. However, retained fragments did not increase the risk of infection or seizure. CONCLUSION: Our results suggest that a less aggressive approach, consisting of minimal local debridement and removal of the bone and metal fragments that are easily accessible, can be successfully used in civilian gunshot wounds to the brain.

Atlantoaxial rotatory dislocation (AARD) is an uncommon disorder of childhood in which clinical diagnosis is generally difficult and often made late. It is very rare in adults because of the unique biomechanical features of the atlantoaxial articulation. We report a case of post-traumatic AARD in an adult. Reduction was difficult to obtain by skull traction and gentle manipulation. Therefore, the patient was treated surgically by an open reduction, transpedicular screw fixation, and posterior C1-2 wiring with graft. The normal atlantoaxial relation was restored with disappearance of torticollis. Postoperatively, the patient remains neurologically intact and has radiographic documentation of fusion. Atlantoaxial transpedicular screw fixation can be one of the treatment options for the AARD.

OBJECTIVE: The aim of this study was to identify the prognostic factors for recovery from oculomotor nerve palsy in patients with a posterior communicating artery aneurysm after surgical intervention. METHODS: We retrospectively reviewed 16 patients with a ruptured or unruptured posterior communicating artery aneurysm that was associated with oculomotor nerve palsy and these patients were treated in our hospital between 2002 and 2006. Fifteen of the 16 patients were women, and the patients' ages ranged between 38 and 75 years (mean age: 52.6 years), and the follow up period was from 0.5 to 36 months (mean: 8.75 months). RESULTS: The total number of aneurysmal cases treated over the 5-year study period was 1135, and there were 223 patients (19.6%) with posterior communicating artery aneurysms. Among these 223 patients, 16 (7.2%) presented with third cranial nerve palsy (4 ruptured, 12 unruptured). Ptosis was presented in all cases (100.0%). Extraocular muscle palsy was presented to some degree by 10 cases (62.5%). The affected pupils were dilated and fixed in all patients (100.0%). The ptosis improved completely in 13 patients (81.3%), and incompletely in 3 patients (18.7%) within 6 months. The dilated and fixed pupils were improved in 10 of the 16 patients (62.5%). The extraocular muscle palsies recovered completely in 15 cases within 6 months. The mean interval between palsy onset and the time of surgery was 6.2 days for the complete recovery cases, and 22 days for the incomplete recovery cases. However, recovery of papillary function was unpredictable. CONCLUSIONS: The duration of symptoms and the degree of preoperative deficits are considered as prognostic factors for the postoperative recovery from third nerve palsy in patients with a posterior communicating artery aneurysm.
