Abstract
BACKGROUND Preoperative traction with the Gardner-Wells tongs (PTGWT) is a valuable option for cervical spine injuries with malalignment. The aim of this study was to analyze the factors related to the treatment success of PTGWT. METHODS All consecutive cases with PTGWT due to cervical spine injury with malalignment treated between 01/2010 and 09/2020 were included. Patients' records were reviewed for demographic and clinical characteristics. Treatment success was evaluated upon the angle correction in the sagittal plane using the computed tomography scans before and after the treatment. RESULTS Of 20 patients in the final analysis (median age: 77.5 years; 12 females [60%]), 14 individuals were treated for the type-II odontoid fracture, and six cases presented with subluxation fractures between C3 and C7. After PTGWT and subsequent intraoperative reposition, there was an improvement of the median deviation angle from initial 32° to 5.5°. PTGWT resulted in a significant improvement of the median deviation angle for the odontoid (17°, P<0.0001), but not for the subluxation (4°, P=0.10) fractures. The time interval between trauma and PTGWT was associated with the treatment success of subluxation (P=0.051) but not of odontoid (P=0.87) fractures. Older individuals aged ≥51 years showed better reposition results with PTGWT (17° vs. 7.5°, P=0.02). There were no PTGWT-related complications in the cohort. CONCLUSIONS PTGWT is an effective and safe treatment for cervical spine injuries with malalignment. The patients with odontoid fractures might particularly profit from the PTGWT. Treatment delay seems more relevant for PTGWT success in subluxation than in odontoid fractures.

Abstract
PURPOSE Spinal cavernous malformations (SCM) present a risk for intramedullary hemorrhage (IMH), which can cause severe neurologic deficits. Patient selection and time of surgery have not been clearly defined. METHODS This observational study included SCM patients who underwent surgery in our department between 2003 and 2021. Inclusion required baseline clinical factors, magnetic resonance imaging studies, and follow-up examination. Functional outcome was assessed using the Modified McCormick scale score. RESULTS Thirty-five patients met the inclusion criteria. The mean age was 44.7 ± 14.5 years, and 60% of the patients were male. In univariate analysis, the unfavorable outcome was significantly associated with multiple bleeding events (p = .031), ventral location of the SCM (p = .046), and incomplete resection (p = .028). The time between IMH and surgery correlated with postoperative outcomes (p = .004), and early surgery within 3 months from IMH was associated with favorable outcomes (p = .033). This association remained significant in multivariate logistic regression analysis (p = .041). CONCLUSIONS Removal of symptomatic SCM should be performed within 3 months after IMH when gross total resection is feasible. Patients with ventrally located lesions might be at increased risk for postoperative deficits.

Abstract
OBJECTIVE The aim of this study was to investigate the functional outcome in spinal cavernous malformation (SCM) patients with single or multiple intramedullary hemorrhagic events. METHODS SCM patients who were conservatively treated between 2003 and 2021 and had complete clinical baseline characteristics, an MRI data set, at least one SCM-related intramedullary hemorrhage (IMH), and at least one follow-up examination were included in this study. Functional status was assessed using the modified McCormick Scale score at diagnosis, before and after each bleeding event, and at the last follow-up. RESULTS A total of 45 patients were analyzed. Univariate analysis identified multiple bleeding events as the only statistically significant predictor for an unfavorable functional outcome at the last follow-up (OR 15.28, 95% CI 3.22-72.47; p < 0.001). Patients significantly deteriorated after the first hemorrhage (29.0%, p = 0.006) and even more so after the second hemorrhage (84.6%, p = 0.002). Multiple bleeding events were significantly associated with functional deterioration at the last follow-up (76.9%, p = 0.003). The time between the last IMH and the last follow-up did not influence this outcome. CONCLUSIONS IMH due to SCM is linked to functional worsening. Such outcomes tend to improve after each hemorrhage, but the probability of full recovery declines with each bleeding event.

Abstract
Simple Summary The WHO classification of tumors of the central nervous system described for the first time the extremely rare entity of rosette-forming glioneuronal tumors (RGNT, CNS WHO grade 1) in 2007. Due to the rarity of this entity in the pineal region, no specific therapy guidelines currently exist. With our large cohort of patients treated at a single center (from August 2018–June 2021) and with the already described cases in the literature, we would like to highlight possible therapy and follow-up concepts. After the main symptoms of headache or generalized epileptic seizure, cystic lesions adjacent to the pineal gland and the third ventricle were diagnosed in imaging. None of the patients underwent additional chemotherapy or radiotherapy after gross total (GTR)/subtotal resection or endoscopic biopsy. In cases where surgical resection seems feasible with a reasonable surgical risk, we advocate GTR. Long-term MRI follow-up is essential to detect a slow tumor progression. Abstract Background: Rosette-forming glioneuronal tumor (RGNT) is an extremely rare entity described for the first time in the WHO classification of tumors of the central nervous system in 2007. Predominantly, single case reports of RGNT in the pineal region have been published, and specific therapy concepts are pending. Methods: The study group comprised all patients with the RGNT (CNS WHO grade 1) in the pineal region that underwent microsurgical tumor removal in our center (August 2018–June 2021). Surgical strategy, histological findings, and clinical outcome are presented, and the results are evaluated and compared to published case reports. Results: Four male patients aged under 50 years (range between 20 and 48 years) and one female patient, 51 years old, were included in this study. Chronic headaches and generalized epileptic seizures were the main symptoms. Supra-cerebellar infratentorial gross total tumor resection (GTR) was performed in two cases, two patients underwent subtotal tumor resection, and an endoscopic biopsy was performed in case five. Conclusion: In cases where surgical resection seems feasible with a reasonable surgical risk, we advocate GTR. Regular and long-term MRI follow-up is essential to detect a slow tumor progression. The role of additional chemotherapy or radiotherapy remains unclear.

Abstract
Background and Objectives: Spinal schwannomas are benign tumours that can present with various symptoms such as pain, radiculopathy and neurological deficit. Gross total resection (GTR) is of key importance for local recurrence. The aim of this study is to describe the clinical characteristics, resection rate, clinical outcome, as well as tumour recurrence, in patients with non-syndromic spinal schwannomas and to clarify which factors affect the resection rate. Materials and Methods: Patients with non-syndromic spinal schwannomas that underwent surgical resection between January 2009 and December 2018 at a single institution were included. Demographic parameters, clinical symptoms, tumour localisation and size, surgical approach and complications were noted. Factors influencing the extent of resection, the surgeon’s decision regarding the approach and the occurrence of new postoperative deficits were evaluated. Results: Fifty patients (18 females) were included. The most common presenting symptom was radiculopathy (88%). The lumbar spine was the most commonly affected site (58%). Laminotomy (72%) was the preferred surgical approach overall and specifically for exclusively intraspinal schwannomas (p = 0.02). GTR was achieved in 76.0% (n = 38). In multivariate analysis, only tumour localisation within the spinal canal (p = 0.014) independently predicted GTR, whereas the type of approach (p = 0.50) and tumour volume (p = 0.072) did not. New postoperative persisting deficits could not be predicted by any factor, including the use and alteration of intraoperative neuromonitoring. Recurrence was observed in four cases (8%) and was significantly higher in cases with STR (p = 0.04). Conclusions: In this retrospective study, GTR was solely predicted by tumour localisation within the spinal canal. The decision regarding the utilisation of different surgical approaches was solely influenced by the same factor. No factor could predict new persisting deficits. Tumour recurrence was higher in STR.

Abstract
OBJECTIVE Cavernous spinal cord malformations (SCMs) are believed to have a high rate of bleeding. The risk of intramedullary hemorrhage (IMH) or recurrent IMH and the neurological impact of bleeding events are important for clinical decision-making and could impact current treatment strategies. METHODS The authors screened their institutional database for patients with cavernous SCM treated between 2003 and 2020. Patients with complete MRI data sets and clinical baseline characteristics were included. Surgically treated patients were censored after cavernous SCM removal. Neurological functional status was obtained using the modified McCormick (MMcC) scale at diagnosis, first IMH, and second IMH. Kaplan-Meier and Cox regression analyses were performed to determine the cumulative 5-year risk for hemorrhage or rehemorrhage. RESULTS Seventy-one patients with cavernous SCM were analyzed. Cox regression analysis identified previous IMH (hazard ratio 7.86, 95% confidence interval 1.01-61.47, p = 0.049) as an independent predictor for rehemorrhage during the 5-year follow-up. The cumulative 5-year risk of bleeding or rebleeding was 41.3% for cavernous SCM. The MMcC score significantly deteriorated in 75% of patients after recurrent hemorrhage (p = 0.012). CONCLUSIONS During untreated 5-year follow-up, a considerably increased risk for hemorrhage or rehemorrhage was found in cavernous malformations of the spinal cord compared to cerebral cavernous malformations. Neurological function significantly deteriorates after the second bleeding. The probability of recurrent IMH increased significantly after initial presentation with hemorrhage.

Abstract
Objective: Spinal cord ependymomas account for 3–6% of all central nervous system tumors and around 60% of all intramedullary tumors. The aim of this study was to analyze the neurological outcome after surgery and to determine prognostic factors for functional outcome. Patients and Methods: Patients treated surgically due to a spinal cord ependymoma between 1990 and 2018 were retrospectively included. Demographics, neurological symptoms, radiological parameters, histopathology, and neurological outcome (using McCormick Score [MCS]) were analyzed. Possible prognostic factors for neurological outcome were evaluated. Results: In total, 148 patients were included (76 males, 51.4%). The mean age was 46.7 ± 15.3 years. The median follow-up period was 6.8 ± 5.4 years. The prevalence was mostly in the lumbar spine (45.9%), followed by the thoracic spine (28.4%) and cervical spine (25.7%). Gross-total resection was achieved in 129 patients (87.2%). The recurrence rate was 8.1% and depended on the extent of tumor resection (p = 0.001). Postoperative temporary neurological deterioration was observed in 63.2% of patients with ependymomas of the cervical spine, 50.0% of patients with ependymomas of the thoracic spine, and 7.4% of patients with ependymomas of the lumbosacral region. MCS 1–2 was detected in nearly two-thirds of patients with cervical and thoracic spinal cord ependymoma 36 months after surgery. Neurological recovery was superior in thoracic spine ependymomas compared with cervical spine ependymomas. Poor preoperative functional condition (MCS >2), cervical and thoracic spine location, and tumor extension >2 vertebrae were independent predictors of poor neurological outcome. Conclusion: Neurological deterioration was seen in the majority of cervical and thoracic spine ependymomas. Postoperative improvement was less in thoracic cervical spine ependymomas compared with thoracic spine ependymomas. Poor preoperative status and especially tumor extension >2 vertebrae are predictors of poor neurological outcome (MCS >2).

Abstract
BACKGROUND Hormone and human epidermal growth factor receptor 2 (HER2/neu) receptor status is prognostic and predictive in breast cancer (BC) and guides the choice of therapy. However, owing to receptor conversion, the receptor status can differ in metastases compared with that of the primary tumor. The aim of the present study was to analyze the prognostic value of receptor status, receptor conversion, and clinical parameters in patients with resected BC brain metastases (BMs). METHODS Patients with BCBMs treated at our institution from July 2007 to December 2019 were eligible for the present study. The receptor status of the BC and corresponding BMs and the occurrence of receptor conversion were separately recorded for 3 common receptors: HER2/neu, estrogen receptor, and progesterone receptor. The association between the receptor status or receptor conversion and clinical parameters was adjusted for outcome-relevant patient and tumor characteristics. RESULTS The final analysis included 78 patients. HER2/neu receptor status in BMs was associated with overall survival (P = 0.033). Receptor conversion was identified in 39 patients (50.0%): HER2/neu, n = 9 (11.5%); estrogen receptor, n = 22 (28.2%); and progesterone receptor, n = 25 (32.1%). In the final multivariate Cox regression analysis, HER2/neu receptor conversion (adjusted hazard ratio [aHR], 3.58; P = 0.006), Karnofsky performance status score <70% (aHR, 3.11; P = 0.048), infratentorial BM location (aHR, 2.49; P = 0.007), and age ≥55 years at BM diagnosis (aHR, 2.20; P = 0.046) were independently associated with poorer survival. CONCLUSIONS Of the 3 common BC receptors, only HER2/neu receptor conversion was strongly associated with the prognosis of patients with surgically treated BCBMs. The clinical relevance of the reevaluation of receptor status in BMs favors surgical treatment of patients with noneloquent BCBMs.

Abstract
Background: Degenerative cervical myelopathy (DCM) is the most common reason for spinal cord disease in elderly patients. This study analyzes the preoperative status and postoperative outcome of higher-aged patients in comparison to young and elderly patients in order to determine the benefit to those patients from DCM surgery. Methods: A retrospective analysis of the clinical data, radiological findings, and operative reports of 411 patients treated surgically between 2007 and 2016 suffering from DCM was performed. The preoperative and postoperative neurological functions were evaluated using the modified Japanese Orthopedic Association Score (mJOA Score), the postoperative mJOA Score improvement, the neurological recovery rate (NRR) of the mJOA Score, and the minimum clinically important difference (MCID). The Charlson Comorbidity Index (CCI) was used to evaluate the impact of comorbidities on the preoperative and postoperative mJOA Score. The comparisons were performed between the following age groups: G1: ≤50 years, G2: 51–70 years, and G3: >70 years. Results: The preoperative and postoperative mJOA Score was significantly lower in G3 than in G2 and G1 (p < 0.0001). However, the mean mJOA Score’s improvement did not differ significantly (p = 0.81) between those groups six months after surgery (G1: 1.99 ± 1.04, G2: 2.01 ± 1.04, G: 2.00 ± 0.91). Furthermore, the MCID showed a significant improvement in every age-group. The CCI was evaluated for each age-group, showing a statistically significant group effect (p < 0.0001). Analysis of variance revealed a significant group effect on the delay (weeks) between symptom onset and surgery (p = 0.003). The duration of the stay at the hospital did differ significantly between the age groups (p < 0.0001). Conclusion: Preoperative and postoperative mJOA Scores, but not the extent of postoperative improvement, are affected by the patients’ age. Therefore, patients should be considered for DCM surgery regardless of their age.

Abstract
OBJECTIVE Ruptured middle cerebral artery (MCA) aneurysms are one of the causes of subarachnoid (SAH) or intracerebral hemorrhage (ICH) but the factors associated with the bleeding type are unknown. The aim of the study was to analyze the association of the morphological variations of the Sylvian fissure (SF) and vascular parameters on occurrence of different bleeding patterns in patients with ruptured MCA aneurysms. PATIENTS AND METHODS The data of consecutive 202 patients with ruptured MCA aneurysm of two centers were included for analysis. Patients were divided into three groups: Group 1 with SAH, Group 2 with accompanying ICH and Group 3 with intrasylvian hemorrhage (ISH). The SF was divided into five types according to the previously described classification. Analyzed vascular parameters were aneurysm size, localization, presence of a daughter aneurysm, shape, and angulation of the aneurysm sac. RESULTS A total of 202 patients (141 female, 61 male, mean age 52.4 yr) were included in this study. 67 patients (33.2%) had a SAH, 122 (60.4%) an ICH and 13 (6.4%) presented with ISH. Statistical analysis showed a significant association of narrow and twisted SF types 4 and 5 (p < 0.001) and temporal angulation of the aneurysm (p = 0.030) for occurrence of ICH. All other vascular parameters showed no significant association for any kind of hemorrhage. CONCLUSION Our results allow the conclusion that the complex SF types 4 and 5, as well as the temporal angulation of the aneurysm sac are associated with the occurrence of ICH in ruptured MCA aneurysms.

Abstract
OBJECTIVES Since publication of the ISAT study, the majority of neurovascular centers adhere to "coil first" policy for patients with subarachnoid hemorrhage (SAH). However, final allocation in favor of coiling or clipping is based on anatomic features of ruptured intracranial aneurysms with respect to clinical characteristics of SAH. In this study, we analyzed the parameters relevant for treatment allocation of ruptured anterior communicating artery aneurysms (AComAA). PATIENTS AND METHODS From our institutional SAH database, all cases with ruptured AComAA, which underwent diagnostic subtraction angiography (DSA) with subsequent treatment allocation, were included. The radiographic features of AComAA were collected from pre-treatment DSA. In addition, demographic, clinical and radiographic parameters of SAH were recorded. The variables selected through univariate analyses were subsequently evaluated using multivariate regression analysis. RESULTS Of 300 SAH patients in the final analysis, the majority of the cases underwent endovascular coiling (n = 221, 73.7%). The following aneurysm features were associated with treatment modality in the univariate analysis: maximal sack size (p = 0.034), perpendicular height (p = 0.007), aspect ratio (p < 0.001) and sack/neck-ratio (p = 0.001). Accordingly, the following cutoffs for these variables were defined upon the receiver operating characteristics curves: 5 mm for sack size, 6 mm for perpendicular height, 1.6 for aspect ratio and sack/neck-ratio. In the multivariate analysis, aspect ratio of 1.6 was the only independent predictor of treatment allocation (p = 0.005; aOR = 2.57; 95% CI 1.33-4.96), which remained significant (p = 0.003; aOR = 2.77; 95% CI 1.41-5.45) after adjusting for patients' age, WFNS & Fisher grades, as well as intracerebral hematoma volume. CONCLUSION Although not-routinely assessed during initial allocation treatment, our retrospective analysis proved that aspect ratio is a reliable predictor of treatment allocation of ruptured AComAA. Except for large space-occupying ICH commonly obligating the microsurgical treatment, other clinical and radiographic characteristics of SAH do not seem to be of clinical relevance for the selection of treatment modality.

Abstract
OBJECTIVE Tuberous sclerosis complex (TSC) is a rare multisystem genetic disease. Arterial wall developmental disorders, such as aneurysms, in association with TSC have been well described for extracranial vasculature. The characteristics of intracranial aneurysms (IAs) in TSC have not previously been addressed in the literature. This systematic review was performed to identify and assess the distinct characteristics of IAs in patients with TSC. METHODS The authors searched PubMed, Scopus, and Web of Science for publications describing cases of TSC and IA reported before August 7, 2018. They also report 2 cases of IAs in TSC patients treated at their own institution. RESULTS Thirty-three TSC patients with a total of 42 IAs were included in this review. Three individuals presented with subarachnoid hemorrhage. The IAs were large or giant in 57.1% and fusiform in 45.2% of the cases. Most of the IAs (61.9%, 26 of 42) originated from the internal carotid artery. There was a higher prevalence of pediatric cases (66.7%) and male patients (63.6%, 21 of 32 individuals with known sex) among the collected series. CONCLUSIONS TSC patients with IAs are characterized with a higher proportion of large/giant and fusiform IAs and young age, suggesting rapid aneurysmal growth. Furthermore, there is a distinct location pattern of IAs and an inverse sex ratio than in the healthy population. Large population-based patient registers are required to improve the understanding of epidemiology and pathophysiology of IA formation in TSC.

Abstract
Our propose is to evaluate CT-guided biopsies in suspected spondylodiscitis with respect to puncture site, microbiology findings, histopathology findings and impact on antibiotic therapy. 86 CT-guided spine interventions in suspected spondylodiscitis comprising 201 biopsy procedures were analyzed. Medical records of all patients were screened for microbiology and histopathology reports as well as date, duration and kind of antibiotic therapy. Statistical analyses included calculation of Chi2-tests and logistic regression analyses. Locations of biopsies were intervertebral disc (48.3%), paravertebral soft-tissue (38.3%) and vertebral body (10.9%). Positive microbiological findings were found altogether in 33.8% of cases, positive histopathological findings in 53.6%. Significant associations between positive microbiological findings, positive histopathological findings and antibiotic therapy, respectively, were found. Location of biopsies did not significantly influence rate of positive findings. From the variables age, white blood cell count, serum creatinine and puncture site, none were found to be an independent predictor for a positive microbiological result. We concluded that CT-guided biopsy of intervertebral disc and paravertebral soft tissue yields positive microbiologic findings in a significant proportion of cases. Puncture site is not associated with positive results of microbiology or histopathology.

Abstract
OBJECTIVE Several parameters like extent of resection and MGMT promotor methylation in glioblastoma (GBM) are known to influence survival. Other elements like multifocality and proliferation indices are not commonly used. The aim of the present study was to analyze routinely and not routinely assessed prognostic markers for survival of patients suffering from GBM in a single center. METHODS Adult cases with GBM operated at our institution were included in this survey. The association of age, Karnofsky performance status (KPS), MGMT promotor methylation, Ki67 proliferation index, IDH1/2 mutational status, and multifocality on overall survival (OS) was analyzed in univariate and multivariate cox regression models. RESULTS We analyzed 565 patients with a mean age of 62.2 (18-84) years. Median OS was 12.5 months. MGMT promoter methylation and IDH 1/2 mutation were associated with significant better OS (P < 0.01). In 48 cases (8.5%), the tumor was localized in both hemispheres, which was associated with a significant worse OS than tumor infiltration of 1 hemisphere (P = 0.039). Mean Ki67 proliferation index increased to 18% when both hemispheres were infiltrated. Multivariate analysis for OS revealed IDH 1/2 wildtype (adjusted odds ratio [aOR] 4.3), higher age (aOR 4.2), unmethylated MGMT promotor (aOR 3.5), preoperative KPS score <70 (aOR 1.9), and multifocality (aOR 2.1) as independent parameters for worse survival. CONCLUSIONS This study confirms well-known parameters like MGMT promoter methylation, IDH 1/2 mutational status, KPS, and age as independent prognostic factors for survival and reveals multifocality as further independent prognostic marker for survival. The dismal prognosis of multifocal involvement is associated with an increasing Ki67 proliferation index.

Abstract
OBJECTIVES Intraoperative aneurysm rupture (IOAR) is a common complication during intracranial aneurysm (IA) surgery. In light of the paradigm shift regarding IA selected for clipping in the post-International Subarachnoid Aneurysm Trial (ISAT) era, we aimed to evaluate the risk factors and effects of IOAR in an institutional series of clipped ruptured IA (RIA) and unruptured IA (UIA). MATERIAL AND METHODS All IAs treated with microsurgical clipping at our institution between 2003 and 2016 were eligible for this study. Demographic, clinical, and radiographic factors were correlated with occurrence of IOAR in univariate and multivariate analyses. The effect on outcome was analyzed for RIA and UIA separately. RESULTS Nine hundred and three clipped IAs were included in the final analysis (538 UIA and 365 RIA). IOAR occurred in 163 cases (18.1%), mostly during clipping of RIA (37.5% vs. 4.8%) In multivariate analysis, ruptured status (adjusted odds ratio [aOR], 10.46; P < 0.001), sack size (aOR, 1.05 per mm increase; P = 0.038) and IA location in the anterior communicating artery (aOR, 2.31; P < 0.001) independently predicted IOAR. For RIA cases, IOAR was also independently predicted by rebleeding before therapy (aOR, 3.11; P = 0.033) and clinical severity of subarachnoid hemorrhage (aOR, 1.18 per WFNS grade increase; P = 0.049). IOAR independently predicted poor outcome (aOR, 1.83; P = 0.042) after RIA surgery. In turn, IOAR affected only the risk for cerebral infarct (OR, 3.75; P = 0.003) and incomplete IA occlusion (OR, 3.45; P = 0.003) for UIA cases, but not the outcome (P = 0.263). CONCLUSIONS IOAR was independently predicted by the ruptured status, location, and size of IA and by initial severity of aneurysmal bleeding and pretreatment rebleeding. The influence of IOAR differed between RIA and UIA cases.

Abstract
BACKGROUND Visual impairment (VI) due to neoplastic infiltration of the optic canal (OC) is frequently seen in skull base meningiomas representing a significant restriction in patients` quality of life. However, the delicate anatomy of this region often prevents gross total tumor resection. The aim of the present study was to evaluate the impact of intradural OC decompression and postoperative oncological procedure on preservation of visual acuity in subtotal resected skull base meningiomas. METHODS A retrospective analysis of 31 consecutive patients (19 females, 12 males; mean age 53 [range 18-78]), treated in our institution between 01/2011- 09/2014 was performed. Patients` charts were analyzed with special respect to operative procedure, postoperative treatment and procedural impact on late visual function. RESULTS Most patients (74.2%) had VI prior to surgery. A pterional craniotomy (97%) facilitated subtotal tumor removal in 71% of the patients with no intraoperative and a low rate (6.4%) of postoperative complications. Adjunctive radiotherapy was performed in 19.3% of the patients. Preoperative visual acuity was preserved or improved in 92% of the patients. Substantial tumor regrowth occurred in only 11.2% of the patients. CONCLUSIONS Intradural decompression of the OC stabilizes visual function in subtotally resected skull base meningiomas. Moreover, adjuvant radiotherapy seems to further benefit visual outcome which has to be evaluated in further prospective studies.

Abstract
BACKGROUND AND OBJECTIVE We present a treatment approach for a rare condition of patients with a ventral C1 fracture and a congenital cleft in the posterior arch (half-ring Jefferson fracture) with an intact transverse atlantal ligament. Our technique aims to achieve stability of the atlanto-occipital and atlantoaxial joints while preserving mobility of the upper cervical spine. PATIENTS AND METHODS Two male patients, 43 years and 29 years of age, respectively, were admitted to our hospital due to a fracture of the ventral arch of the atlas with no damage of the transverse atlantal ligament. Both men also presented a congenital cleft of the posterior arch. Initial conservative management with a halo-thoracic vest was performed in one case and failed. As a result, surgical treatment was performed in both cases using bilateral C1 mass screws and a transverse connector. RESULTS The patients showed no neurologic deficits on follow-up examination 4 weeks after surgery with a full range of head and neck motion. Computed tomography (CT) showed no dislocation of the implanted material with good dorsal alignment and a stable ventral fracture distance. Follow-up CT showed osseous stability in both cases with the beginning of bony ossification of the bone graft. CONCLUSION Isolated instable fractures of the ventral arch of the atlas with a congenital cleft of the posterior arch with no damage of the transverse atlantal ligament can be stabilized using bilateral C1 mass screws and a transverse connector preserving upper cervical spine mobility.

Abstract
OBJECTIVE
The aim of this study was to determine seizure outcome, functional outcome, and the withdrawal of antiepileptic drugs (AEDs) after conservative or surgical treatment of patients with new-onset cavernoma-related epilepsy (CRE).
METHODS
The authors conducted a retrospective comparative observational study of 79 consecutive patients, each with a single sporadic cerebral cavernous malformation (CCM) and new-onset CRE.
RESULTS
Forty-one patients underwent initial surgery (IS), and 38 patients underwent initial conservative (IC) treatment. Of those in the latter group, 19 underwent delayed surgical (DS) treatment. At the last follow-up, 88%, 32%, and 79% of patients in the respective groups had been seizure free for at least 2 years (International League Against Epilepsy [ILAE] Class 1; IS vs IC, p < 0.0001) and 78%, 8%, and 58%, respectively, had been off AEDs (IS vs IC, p < 0.0001). The cumulative probability of staying seizure free (ILAE Class 1) during a 5-year period was 73% (mean seizure-free follow-up 49.8 ± 2.7 months, 95% CI 44.4–55.1 months) for the IS group, 22% (mean 31.8 ± 3.6 months, 95% CI 24.8–38.8 months) for the IC group, and 68% (mean 48.6 ± 4.3 months, 95% CI 40.1–57.1 months) for the DS group (IS vs IC p < 0.001). Long-term operative morbidity was 3%, and long-term morbidity in the conservatively treated group was also 3%.
CONCLUSIONS
Patients with CCM and new-onset CRE who underwent IS treatment showed better results in seizure control and the discontinuation of AEDs than the conservatively treated patients. Operative morbidity was comparable to the morbidity from symptomatic CCM hemorrhage in the conservative group. Half of the patients who started with conservative treatment underwent subsequent surgical treatment; however, a longer duration of epilepsy prior to surgery did not worsen postoperative seizure outcome.

Abstract
BACKGROUND AND PURPOSE Acute hydrocephalus is an early and common complication of aneurysmal subarachnoid hemorrhage (SAH). However, considerably fewer patients develop chronic hydrocephalus requiring shunt placement. Our aim was to develop a risk score for early identification of patients with shunt dependency after SAH. METHODS Two hundred and forty-two SAH individuals who were treated in our institution between January 2008 and December 2013 and survived the initial impact were retrospectively analyzed. Clinical parameters within 72 h after the ictus were correlated with shunt dependency. Independent predictors were summarized into a new risk score which was validated in a subsequent SAH cohort treated between January and December 2014. RESULTS Seventy-five patients (31%) underwent shunt placement. Of 23 evaluated variables, only the following five showed independent associations with shunt dependency and were subsequently used to establish the Chronic Hydrocephalus Ensuing from SAH Score (CHESS, 0-8 points): Hunt and Hess grade ≥IV (1 point), location of the ruptured aneurysm in the posterior circulation (1 point), acute hydrocephalus (4 points), the presence of intraventricular hemorrhage (1 point) and early cerebral infarction on follow-up computed tomography scan (1 point). The CHESS showed strong correlation with shunt dependency (P = 0.0007) and could be successfully validated in both internal SAH cohorts tested. Patients scoring ≥6 CHESS points had significantly higher risk of shunt dependency (P < 0.0001) than other patients. CONCLUSION The CHESS may become a valuable diagnostic tool for early estimation of shunt dependency after SAH. Further evaluation and external validation will be required in prospective studies.

Abstract
OBJECTIVE Although most neurovascular centers currently have a coil first policy, the percentage of coiled versus clipped aneurysms, as well as treatment outcomes, varies strongly between these centers. This study evaluates the impact of an increase in clipping caseload on treatment outcome in a large single-center series. METHODS All consecutive patients who underwent microsurgical clipping of unruptured intracranial aneurysms between January 2003 and April 2014 in our department were analyzed retrospectively. According to the change of the chairman in the neurosurgical department (1 September 2008) with a subsequent increase in the clipping volume, the entire cohort was divided into 2 groups with equal time intervals (historic and current cohorts). RESULTS There were 94 clipped unruptured intracranial aneurysms in the historic cohort and 252 in the current cohort. Unfavorable outcome at 6 months postoperatively (defined as modified Rankin Score >2) was observed in 8 cases (8.5%) in the historic cohort and 7 cases (2.8%) in the current cohort (P < 0.0001). The surgical mortality decreased from 3.2% to 0%. Cerebral infarction on postoperative computed tomography scan was observed in 25 cases (26.6%) in the historic cohort and 19 cases (7.5%) in the current cohort (P < 0.0001). Within the current cohort, there was a progressive improvement of surgical outcome over the time. CONCLUSIONS The improvement of the surgical outcome after increasing the clipping caseload underlines the importance of sufficient surgical volume for maintenance of competitive treatment results.

Abstract
BACKGROUND Intradural spinal cord tumors (IDSCTs) in children and young adults are rare diseases. This present study is aimed to demonstrate our experience with a large series of children and young adults with IDSCT. METHODS A total of 50 patients aged <20 years with IDSCT treated in our department between 1990 and 2010 were included in the study. Clinical, histological, and radiological findings, treatment strategies, and clinical outcome were retrospectively assessed. Depending on the relation to the spinal cord, IDSCT were dichotomized into intramedullary SCT (IMSCT) and extramedullary SCT (EMSCT). The functional outcome was evaluated with the Frankel score assessing the longest available follow-up period. RESULTS Mean age was 10.3 years (range 6 months-19 years). IDSCT surgery was performed in 44 patients (88%). A common first symptom in patients with EMSCT was neck and back pain (41%), whereas monoparesis of arms (43%) were often seen in patients with IMSCT. The main duration of the symptoms was longer in patients with IMSCT. The postoperative functional outcome was generally comparable to the preoperative functional condition, while better for EMSCT (P < 0.01). The functional outcome at last follow-up correlated significantly with the preoperative Frankel score (P < 0.002). CONCLUSION Due to the mostly mild impact of the surgery on the functional outcome, the surgical treatment of IDSCT in children and young patients can be uniquely advocated.

Abstract
PURPOSE Spinal injuries are rarely seen in pediatric patients and therapeutic options are still poorly defined. The present study is aimed to present our experience with a rather large series of children and young adults suffering from traumatic spinal injury. PATIENTS AND METHODS Between 1990 and 2010, 75 consecutive pediatric patients with spinal injuries were treated in our institution. Mean age was 15 years, ranging from 3 months to 21 years. Radiological findings, treatment strategies, and clinical outcome were evaluated retrospectively and compared with literature. Forty (53.3%) patients were treated conservatively and 35 patients (47%) surgically using anterior or posterior approaches. Subgroup analysis was performed depending on age groups, severity of neurological symptoms, and localization. RESULTS Main trauma mechanisms were fall in 24 patients (38%) and motor vehicle accidents in 21 patients (28%). Complete neurological deficits were present in 17 individuals (23%) and incomplete in 36 patients (48%). Fractures were most frequently localized at the cervical region (56%) with predilection of the C 5/6 segment. Odontoid fractures were seen in 10 (13%) patients. Fractures of the lumbar and thoracic region were rare. Level of injury or clinical course did not differ between the subgroups (≤15 years versus >15 years). CONCLUSION Nearly three fourths of all radiologically detected spinal injuries are located at the cervical spine. Complete neurological deficits after trauma was associated with a poor outcome, in particular for patients with injuries of the upper cervical spine. The use of autologous bone graft was associated with favorable long-term results and should be considered as the material of first choice for vertebral body and disc replacement.

Abstract
Objectives Pulsatile tinnitus (PT) is a rare complaint, but can be a symptom of life-threatening disease. It is often caused by vascular pathologies, e.g. dural arteriovenous fistula (dAVF), arteriovenous malformation (AVM) or vascularized tumors. The current diagnostic pathway includes clinical examination, cranial MRI and additional DSA. The aim of this study was to evaluate the diagnostic impact of DSA in the diagnostic workup of patients with PT in comparison to MRI alone. Methods Retrospectively, 54 consecutive patients with pulsatile tinnitus were evaluated. All patients had a diagnostic workup including cranial MRI and DSA. MRI examinations were blinded to the results of DSA and retrospectively analyzed in consensus by two experienced neuroradiologists. The MR-examinations were evaluated for each performed sequence separately: time-of-flight-angiography, ce-MRA, T2, ce-T1-sequence and ce-T1-sequence with fat saturation. Results 37 of the 54 patients revealed a pathology explaining PT on MRI, which was detected by the readers in 100% and proofed by means of DSA. 24 dAVF, four paraganglioma, two AVM and seven more pathologies were described. All patients without pathology on MRI did also not show any pathology in DSA. Conclusions MR imaging is sufficient to exclude pathology in patients with pulsatile tinnitus.

Abstract
Purpose Conventional saturation pulses cannot be used for 7 Tesla ultra-high-resolution time-of-flight magnetic resonance angiography (TOF MRA) due to specific absorption rate (SAR) limitations. We overcome these limitations by utilizing low flip angle, variable rate selective excitation (VERSE) algorithm saturation pulses. Material and Methods Twenty-five neurosurgical patients (male n = 8, female n = 17; average age 49.64 years; range 26–70 years) with different intracranial vascular pathologies were enrolled in this trial. All patients were examined with a 7 Tesla (Magnetom 7 T, Siemens) whole body scanner system utilizing a dedicated 32-channel head coil. For venous saturation pulses a 35° flip angle was applied. Two neuroradiologists evaluated the delineation of arterial vessels in the Circle of Willis, delineation of vascular pathologies, presence of artifacts, vessel-tissue contrast and overall image quality of TOF MRA scans in consensus on a five-point scale. Normalized signal intensities in the confluence of venous sinuses, M1 segment of left middle cerebral artery and adjacent gray matter were measured and vessel-tissue contrasts were calculated. Results Ratings for the majority of patients ranged between good and excellent for most of the evaluated features. Venous saturation was sufficient for all cases with minor artifacts in arteriovenous malformations and arteriovenous fistulas. Quantitative signal intensity measurements showed high vessel-tissue contrast for confluence of venous sinuses, M1 segment of left middle cerebral artery and adjacent gray matter. Conclusion The use of novel low flip angle VERSE algorithm pulses for saturation of venous vessels can overcome SAR limitations in 7 Tesla ultra-high-resolution TOF MRA. Our protocol is suitable for clinical application with excellent image quality for delineation of various intracranial vascular pathologies.

Abstract
BACKGROUND AND OBJECT Cranial dural arteriovenous fistulas are commonly treated using an endovascular method. In comparison to intracerebral arteriovenous malformations, it is important to reach the venous part of these malformations to maintain a complete occlusion. Therefore, often the venous side is totally occluded using coils and∕or glue. PATIENT AND METHODS We describe a patient with an initially Type IIab (Cognard classification) left occipital cranial fistula. The patient suffered from an intense pulsate tinnitus. Therefore, the first embolization was performed using an approach via the dilated left middle meningeal artery using Onyx. The shunt of the fistula was reduced significantly but total occlusion was impossible. Therefore, the venous approach was used. Over a guiding catheter in the sigmoid sinus, the venous side of the fistula could be reached with a microcatheter. This part of the fistula was then completely occluded using coated and bare coils, without occluding the adjacent sinus. Control angiography of all previous feeders showed a complete occlusion of the fistula (used classification: Cognard). RESULTS The fistula was entirely occluded. The patient's outcome was excellent. The patient did not develop any symptoms and no complication occurred due to the treatment. CONCLUSIONS Direct occlusion of the venous part of an arteriovenous cranial fistula can be an option before an occlusion of the sinus has to be performed. This approach can lead to reduction of risk during the endovascular procedure and risk reduction in long-term follow-up.
