    Background The identification of psychological risk factors is important for the selection of patients before spinal surgery. Moreover, the effect of surgical decompression in lumbar spinal stenosis (LSS) on psychological outcome is not previously well analyzed. Aim of paper to investigate clinical and psychological outcome after surgery for LSS and the effect of depressive symptoms and anxiety on the clinical outcome. Materials and methods A total of 25 patients with symptomatic LSS underwent decompressive surgery with or without spinal stabilization were prospectively enrolled in this observational surgery. The Symptom Checklist-90-Revised (SCL-90-R) was used to assess global psychological distress with a summary score termed Global Severity Index (GSI) and single psychological disorders including depression (DEP) and anxiety (ANX). The clinical outcome of surgery was evaluated with the Oswestry Disability Index (ODI) and visual analogue scale (VAS) pain assessment. Results Compared with baseline, there was a statistically significant improvement in VAS, ODI and GSI after surgery (p<0.05) in all patients. Univariate analysis revealed that patients with high GSI and anxiety and depression scores had significantly higher ODI and VAS scores in the follow-up with a bad outcome. Conclusions Surgery for spinal stenosis was effective to treat pain and disability. In this prospective study baseline global psychological distress, depression and anxiety were associated with poorer clinical outcome

    Treatment modalities affecting quality of life and survival in elderly brain glioblastoma patients are not well defined. A single-institution data were analyzed during a 3-year period to disclose prognostic difference in management related to age. Karnofsky Performance Scale (KPS), overall survival (OS), and adjuvant therapy were evaluated. The case group comprised of elderly patients (>75 years), while the control group included those of younger age (<65 years). The investigated variables were correlated between the groups. Twenty elderly patients and a corresponding number of younger ones were analyzed. Preoperative KPS >70 indicated longer overall survival. Statistically significant correlation was recorded in both the control (p=0.036) and case (p=0.0053) groups. Lower postoperative KPS was significantly correlated with shorter OS in elderly patients (p=0.023). The correlation between the extent of tumor resection and OS was statistically significant in younger patients only (p=0.04). Overall survival was significantly shorter in elderly patients regardless of the extent of tumor resection (p=0.0057). Adjuvant therapy was significantly associated with longer OS in both the case (p=0.032) and control (p=0.013) groups. Elderly population is a more endangered group of surgical brain glioblastoma patients having lower quality of life and shorter overall survival. The management protocol should be personalized for each individual case in this age group of patients to reduce postoperative complications and grant a satisfactory quality of life.Modaliteti liječenja od utjecaja na kvalitetu života i preživljavanje starijih bolesnika s glioblastomom još nisu jasno određeni. Kako bi se utvrdila prognostička razlika u primijenjenim oblicima liječenja u odnosu na dob bolesnika analizirani su podaci dobiveni trogodišnjim istraživanjem uzorka. Istraživani su sljedeći pokazatelji: Karnofskyjeva ljestvica (KPS), vrijeme ukupnog preživljavanja i primjena pomoćnog liječenja. Oglednu skupinu činili su stariji bolesnici (≥75 godina), a kontrolnu skupinu oni mlađe dobi (≤65 godina). Međusobno su uspoređivani istraživani parametri iz obje skupine bolesnika. Promatrano je 20 starijih i odgovarajući broj mlađih bolesnika. Prijeoperacijski KPS >70 upućivao je na dulje sveukupno preživljavanje. Statistički značajna korelacija zabilježena je u bolesnika kontrolne (p=0,036) i ogledne (p=0,0053) skupine. Niže poslijeoperacijske vrijednosti KPS bile su značajno povezane s kraćim vremenom preživljavanja u starijih bolesnika (p=0,023). Korelacija između opsežnosti tumorske resekcije i sveukupnog preživljavanja bila je statistički značajna samo u mlađoj dobnoj skupini (p=0,04). Vrijeme sveukupnog preživljavanja bilo je značajno kraće u starijih bolesnika neovisno o stupnju kirurške resekcije (p=0,0057). Primjena pomoćne terapije bila je značajno povezana s duljim sveukupnim preživljavanjem u oglednoj (p=0,032) i kontrolnoj (p=0,013) skupini. U zaključku, starija je populacija ugroženija skupina kirurških bolesnika s glioblastomom u kojih je smanjena kvaliteta života i skraćeno vrijeme sveukupnog preživljavanja. Stoga je potrebno protokol liječenja prilagoditi svakom pojedinom bolesniku iz ove dobne skupine kako bi se smanjio udio poslijeoperacijskih komplikacija i poboljšala kvaliteta života

    Study DesignRetrospective study with long-term follow-up.PurposeTo evaluate the long-term incidence of adjacent segment degeneration (ASD) and clinical outcomes in a consecutive series of patients who underwent spinal decompression associated with dynamic or hybrid stabilization with a Flex+TM stabilization system (SpineVision, Antony, France) for lumbar spinal stenosis.Overview of LiteratureThe incidence of ASD and clinical outcomes following dynamic or hybrid stabilization with the Flex+TM system used for lumbar spinal stenosis have not been well investigated.MethodsTwenty-one patients with lumbar stenosis and probable post-decompressive spinal instability underwent decompressive laminectomy followed by spinal stabilization using the Flex+TM stabilization system. The indication for a mono-level dynamic stabilization was a preoperative magnetic resonance imaging (MRI) demonstrating evidence of severe disc disease associated with severe spinal stenosis. The hybrid stabilization (rigid-dynamic) system was used for multilevel laminectomies with associated initial degenerative scoliosis, first-grade spondylolisthesis, or rostral pathology.ResultsThe improvement in Visual Analog Scale and Oswestry Disability Index scores at follow-up were statistically significant (p<0.0001 and p<0.0001, respectively). At the 5–8-year follow-up, clinical examination, MRI, and X-ray findings showed an ASD complication with pain and disability in one of 21 patients. The clinical outcomes were similar in patients treated with dynamic or hybrid fixation.ConclusionsPatients treated with laminectomy and Flex+TM stabilization presented a satisfactory clinical outcome after 5–8 years of follow-up, and ASD incidence in our series was 4.76% (one patient out of 21). We are aware that this is a small series, but our long-term follow-up may be sufficient to contribute to the expanding body of literature on the development of symptomatic ASD associated with dynamic or hybrid fixation

    Objective: Chronic subdural hematoma (CSDH) is one of the most frequent neurosurgical conditions in people aging between 70 and 80 years. The cranial burr-hole (CBH) with surgical cavity irrigation through the burr hole and closed drainage system is the treatment of choice but -post-operative outcome can be influenced by pneumocephalus. In this study, we aimed to explore the relationship between the anterior-posterior (AP) burr-hole position and the volume of post-operative pneumocephalus. Patients and Methods: We identified 153 consecutive patients who underwent BHC for CSDH at our institution. Baseline and post-operative data were retrospectively collected from medical records. The linear regression model was used to estimate the association between the volume of post-operative subdural air collection and burr-hole position along with other baseline patients and hematoma variables. Results: The AP position of the burr-hole was independently associated with the volume of post-operative pneumocephalus: lower volume of subdural air was observed in patients with more anterior cranial burr-hole. Conclusions: In patients operated for CSDH, the cranial burr-hole should be performed anteriorly to grant a lesser amount of subdural post-operative air collection

    Background: The development or expansion of a cerebral hemorrhagic contusion after decompressive craniectomy (DC) for traumatic brain injury (TBI) occurs commonly and it can result in an unfavorable outcome. However, risk factors predicting contusion expansion after DC are still uncertain. The aim of this study was to identify the factors associated with the growth or expansion of hemorrhagic contusion after DC in TBI. Then we evaluated the impact of contusion progression on outcome.Methods: We collected the data of patients treated with DC for TBI in our Center. Then we analyzed the risk factors associated with the growth or expansion of a hemorrhagic contusion after DC.Results: 182 patients (149 males and 41 females) were included in this study. Hemorrhagic contusions were detected on the initial CT scan or in the last CT scan before surgery in 103 out of 182 patients. New or blossoming hemorrhagic contusions were registered after DC in 47 patients out of 182 (25.82%). At multivariate analysis, only the presence of an acute subdural hematoma (p = 0.0076) and a total volume of contusions &gt;20 cc before DC (p = &lt; 0.0001) were significantly associated with blossoming contusions. The total volume of contusions before DC resulted to have higher accuracy and ability to predict postoperative blossoming of contusion with strong statistical significance rather than the presence of acute subdural hematoma (these risk factors presented respectively an area under the curve [AUC] of 0.896 vs. 0.595; P &lt; 0.001). Patients with blossoming contusions presented an unfavorable outcome compared to patients without contusion progression (p &lt; 0.0185).Conclusions: The presence of an acute subdural hematoma was associated with an increasing rate of new or expanded hemorrhagic contusions after DC. The total volume of hemorrhagic contusions &gt; 20 cc before surgery was an independent and extremely accurate predictive radiological sign of contusion blossoming in decompressed patients for severe TBI. After DC, the patients who develop new or expanding contusions presented an increased risk for unfavorable outcome

    Metastases involving the clivus and craniocervical junction (CCJ) are extremely rare. Skull base involvement can result in cranial nerve palsies, while an extensive CCJ involvement can lead to spinal instability. We describe an unusual case of clival and CCJ metastases presenting with VI cranial nerve palsy and neck pain secondary to CCJ instability from metastatic bladder urothelial carcinoma. The patient was first treated with an endoscopic endonasal approach to the clivus for decompression of the VI cranial nerve and then with occipitocervical fixation and fusion to treat CCJ instability. At the 6-month follow-up, the patient experienced complete recovery of VI cranial nerve palsy. To the best of our knowledge, the simultaneous involvement of the clivus and the CCJ due to metastatic bladder carcinoma has never been reported in the literature. Another peculiarity of this case was the presence of both VI cranial nerve deficit and spinal instability. For this reason, the choice of treatment and timing were challenging. In fact, in case of no neurological deficit and spinal stability, palliative chemo- and radiotherapy are usually indicated. In our patient, the presence of progressive diplopia due to VI cranial nerve palsy required an emergent surgical decompression. In this scenario, the extended endoscopic endonasal approach was chosen as a minimally invasive approach to decompress the VI cranial nerve. Posterior occipitocervical stabilization is highly effective in avoiding patient’s neck pain and spinal instability, representing the approach of choice

    Background: Surgical treatment of spinal metastases should be tailored to provide pain control, neurological deficit improvement, and vertebral stability with low operative morbidity and mortality. The aim of this study was to analyze the predictive value of some preoperative factors on overall survival in patients undergoing surgery for spinal metastases. Methods: We retrospectively analyzed a consecutive series of 81 patients who underwent surgery for spinal metastases from 2015 and 2021 in the Clinic of Neurosurgery of Ancona (Italy). Data regarding patients’ baseline characteristics, preoperative Karnofsky Performance Status Score (KPS), and Frankel classification grading system, histology of primary tumor, Tokuhashi revised and Tomita scores, Spine Instability Neoplastic Score, and Epidural Spinal Cord Compression Classification were collected. We also evaluated the interval time between the diagnosis of the primary tumor and the onset of spinal metastasis, the type of surgery, the administration of adjuvant therapy, postoperative pain and Frankel grade, and complications after surgery. The relationship between patients’ overall survival and predictive preoperative factors was analyzed by the Kaplan–Meier method. For the univariate and multivariate analysis, the log-rank test and Cox regression model were used. P ≤ 0.05 was considered as statistically significant. Results: After surgery, the median survival time was 13 months. In our series, the histology of the primary tumor (P &lt; 0.001), the Tomita (P &lt; 0.001) and the Tokuhashi revised scores (P &lt; 0.001), the preoperative KPS (P &lt; 0.001), the adjuvant therapy (P &lt; 0.001), the postoperative Frankel grade (P &lt; 0.001), and the postoperative pain improvement (P &lt; 0.001) were significantly related to overall survival in the univariate analysis. In the multivariate analysis, the Tomita (P &lt; 0.001), Tokuhashi revised scores (P &lt; 0.001), and the adjuvant therapy were confirmed as independent prognostic factors. Conclusion: These data suggest that patients with limited extension of primitive tumor and responsive to the adjuvant therapy are the best candidates for surgery with better outcome

    Study DesignRetrospective study.PurposeThe aim of our study was to analyze the safety and effectiveness of posterior pedicle screw fixation for treatment of pyogenic spondylodiscitis (PSD) without formal debridement of the infected tissue.Overview of LiteraturePosterior titanium screw fixation without formal debridement of the infected tissue and anterior column reconstruction for the treatment of PSD is still controversial.MethodsFrom March 2008 to June 2013, 18 patients with PSD underwent posterior titanium fixation with or without decompression, according to their neurological deficit. Postero-lateral fusion with allograft transplantation alone or bone graft with both the allogenic bone and the autologous bone was also performed. The outcome was assessed using the visual analogue scale (VAS) for pain and the Frankel grading system for neurological status. Normalization both of C-reactive protein (CRP) and erythrocyte sedimentation rate was adopted as criterion for discontinuation of antibiotic therapy and infection healing. Segmental instability and fusion were also analyzed.ResultsAt the mean follow-up time of 30.16 months (range, 24–53 months), resolution of spinal infection was achieved in all patients. The mean CRP before surgery was 14.32±7.9 mg/dL, and at the final follow-up, the mean CRP decreased to 0.5±0.33 mg/dL (p <0.005). Follow-up computed tomography scan at 12 months after surgery revealed solid fusion in all patients. The VAS before surgery was 9.16±1.29 and at the final follow-up, it improved to 1.38±2.03, which was statistically significant (p <0.05). Eleven patients out of eighteen (61.11%) with initial neurological impairment had an average improvement of 1.27 grades at the final follow-up documented with the Frankel grading system.ConclusionsPosterior screw fixation with titanium instrumentation was safe and effective in terms of stability and restoration of neurological impairment. Fixation also rapidly reduced back pain

    Surgical management of Glioma Grade 4: technical update from the neuro-oncology section of the Italian Society of Neurosurgery (SINch®): a systematic review

    Purpose: The extent of resection (EOR) is an independent prognostic factor for overall survival (OS) in adult patients with Glioma Grade 4 (GG4). The aim of the neuro-oncology section of the Italian Society of Neurosurgery (SINch®) was to provide a general overview of the current trends and technical tools to reach this goal. Methods: A systematic review was performed. The results were divided and ordered, by an expert team of surgeons, to assess the Class of Evidence (CE) and Strength of Recommendation (SR) of perioperative drugs management, imaging, surgery, intraoperative imaging, estimation&nbsp;of EOR, surgery at tumor progression and surgery in elderly patients. Results: A total of 352 studies were identified, including 299 retrospective studies and 53 reviews/meta-analysis. The use of Dexamethasone and the avoidance of prophylaxis with anti-seizure medications reached a CE I and SR A. A preoperative imaging standard protocol was defined with CE II and SR B and usefulness of an early postoperative MRI, with CE II and SR B. The EOR was defined the strongest independent risk factor for both OS and tumor recurrence with CE II and SR B. For intraoperative imaging only the use of 5-ALA reached a CE II and SR B. The estimation of EOR was established to be fundamental in planning postoperative adjuvant treatments with CE II and SR B and the stereotactic image-guided brain biopsy to be the procedure of choice when an extensive surgical resection is not feasible (CE II and SR B). Conclusions: A growing number of evidences evidence support the role of maximal safe resection as primary OS predictor in GG4 patients. The ongoing development of intraoperative techniques for a precise real-time identification of peritumoral functional pathways enables surgeons to maximize EOR minimizing the post-operative morbidity
