INTRODUCTION: Pediatric intracranial aneurysms (IAs) are rare and have distinct clinical profiles compared to adult IAs. They differ in location, size, morphology, presentation, and treatment strategies. We present our experience with pediatric IAs over an 18-year period using surgical and endovascular treatments and review the literature to identify commonalities in epidemiology, treatment, and outcomes. METHODS: We identified all patients

INTRODUCTION: A greater extent of resection of the contrast-enhancing (CE) tumour part has been associated with improved outcomes in glioblastoma. Recent results suggest that resection of the non-contrast-enhancing (NCE) part might yield even better survival outcomes (supramaximal resection, SMR). Therefore, this study evaluates the efficacy and safety of SMR with and without mapping techniques in high-grade glioma (HGG) patients in terms of survival, functional, neurological, cognitive and quality of life outcomes. Furthermore, it evaluates which patients benefit the most from SMR, and how they could be identified preoperatively. METHODS AND ANALYSIS: This study is an international, multicentre, prospective, two-arm cohort study of observational nature. Consecutive glioblastoma patients will be operated with SMR or maximal resection at a 1:1 ratio. Primary endpoints are (1) overall survival and (2) proportion of patients with National Institute of Health Stroke Scale deterioration at 6 weeks, 3 months and 6 months postoperatively. Secondary endpoints are (1) residual CE and NCE tumour volume on postoperative T1-contrast and FLAIR (Fluid-attenuated inversion recovery) MRI scans; (2) progression-free survival; (3) receipt of adjuvant therapy with chemotherapy and radiotherapy; and (4) quality of life at 6 weeks, 3 months and 6 months postoperatively. The total duration of the study is 5 years. Patient inclusion is 4 years, follow-up is 1 year. ETHICS AND DISSEMINATION: The study has been approved by the Medical Ethics Committee (METC Zuid-West Holland/Erasmus Medical Center; MEC-2020-0812). The results will be published in peer-reviewed academic journals and disseminated to patient organisations and media.

PURPOSE: Tethered cord syndrome (TCS) is characterized by abnormal attachment of the spinal cord neural elements to surrounding tissues. The most common symptoms include pain, motor or sensory dysfunction, and urologic deficits. Although TCS is common in children, there is a significant heterogeneity in outcomes reporting. We systematically reviewed surgical indications and postoperative outcomes to assess the need for a grading/classification system. METHODS: PubMed and EMBASE searches identified pediatric TCS literature published between 1950 and 2023. Studies reporting surgical interventions, ≥ 6-month follow-up, and ≥ 5 patients were included. RESULTS: Fifty-five studies representing 3798 patients were included. The most commonly reported non-urologic symptoms were nonspecific lower-extremity motor disturbances (36.4% of studies), lower-extremity/back pain (32.7%), nonspecific lower-extremity sensory disturbances (29.1%), gait abnormalities (29.1%), and nonspecific bowel dysfunction/fecal incontinence (25.5%). Urologic symptoms were most commonly reported as nonspecific complaints (40.0%). After detethering surgery, retethering was the most widely reported non-urologic outcome (40.0%), followed by other nonspecific findings: motor deficits (32.7%), lower-extremity/back/perianal pain (18.2%), gait/ambulation function (18.2%), sensory deficits (12.7%), and bowel deficits/fecal incontinence (12.7%). Commonly reported urologic outcomes included nonspecific bladder/urinary deficits (27.3%), bladder capacity (20.0%), bladder compliance (18.2%), urinary incontinence/enuresis/neurogenic bladder (18.2%), and nonspecific urodynamics/urodynamics score change (16.4%). CONCLUSION: TCS surgical literature is highly variable regarding surgical indications and reporting of postsurgical outcomes. The lack of common data elements and consistent quantitative measures inhibits higher-level analysis. The development and validation of a standardized outcomes measurement tool-ideally encompassing both patient-reported outcome and objective measures-would significantly benefit future TCS research and surgical management.

LITT is a minimally-invasive laser ablation technique used to treat a wide variety of intracranial lesions. Difficulties performing intraoperative mapping have limited its adoption for lesions in/near eloquent regions. In this institutional case series, we demonstrate the utility of fMRI-adjunct planning for LITT near language or motor areas. Six out of 7 patients proceeded with LITT after fMRI-based tractography determined adequate safety margins for ablation. All underwent successful ablation without new or worsening postoperative symptoms requiring adjuvant corticosteroids, including those with preexisting deficits. fMRI is an easily accessible adjunct which may potentially reduce chances of complications in LITT near eloquent structures.

OBJECTIVE: Maximal safe resection is the standard of care for patients presenting with lesions concerning for glioblastoma (GBM) on magnetic resonance imaging (MRI). Currently, there is no consensus on surgical urgency for patients with an excellent performance status, which complicates patient counseling and may increase patient anxiety. This study aims to assess the impact of time to surgery (TTS) on clinical and survival outcomes in patients with GBM. METHODS: This is a retrospective study of 145 consecutive patients with newly diagnosed IDH-wild-type GBM who underwent initial resection at the University of California, San Francisco, between 2014 and 2016. Patients were grouped according to the time from diagnostic MRI to surgery (i.e., TTS): ≤ 7, > 7-21, and > 21 days. Contrast-enhancing tumor volumes (CETVs) were measured using software. Initial CETV (CETV1) and preoperative CETV (CETV2) were used to evaluate tumor growth represented as percent change (ΔCETV) and specific growth rate (SPGR; % growth/day). Overall survival (OS) and progression-free survival (PFS) were measured from the date of resection and were analyzed using the Kaplan-Meier method and Cox regression analyses. RESULTS: Of the 145 patients (median TTS 10 days), 56 (39%), 53 (37%), and 36 (25%) underwent surgery ≤ 7, > 7-21, and > 21 days from initial imaging, respectively. Median OS and PFS among the study cohort were 15.5 and 10.3 months, respectively, and did not differ among the TTS groups (p = 0.81 and 0.17, respectively). Median CETV1 was 35.9, 15.7, and 10.2 cm3 across the TTS groups, respectively (p < 0.001). Preoperative biopsy and presenting to an outside hospital emergency department were associated with an average 12.79-day increase and 9.09-day decrease in TTS, respectively. Distance from the treating facility (median 57.19 miles) did not affect TTS. In the growth cohort, TTS was associated with an average 2.21% increase in ΔCETV per day; however, there was no effect of TTS on SPGR, Karnofsky Performance Status (KPS), postoperative deficits, survival, discharge location, or hospital length of stay. Subgroup analyses did not identify any high-risk groups for which a shorter TTS may be beneficial. CONCLUSIONS: An increased TTS for patients with imaging concerning for GBM did not impact clinical outcomes, and while there was a significant association with ΔCETV, SPGR remained unaffected. However, SPGR was associated with a worse preoperative KPS, which highlights the importance of tumor growth speed over TTS. Therefore, while it is ill advised to wait an unnecessarily long time after initial imaging studies, these patients do not require urgent/emergency surgery and can seek tertiary care opinions and/or arrange for additional preoperative support/resources. Future studies are needed to explore subgroups for whom TTS may impact clinical outcomes.

OBJECTIVE: Cystic vestibular schwannomas (cVSs) have more variable and less favorable clinical outcomes after microsurgical resection compared with solid VS (sVS). This study compares the preoperative presentation and postoperative outcomes between cVS and sVS. STUDY DESIGN: Retrospective cohort study. SETTING: Two tertiary skull base referral centers. METHODS: Consecutive adult patients who underwent VS resection from 2016 to 2021 were included. Univariate and multivariate analyses compared differences in baseline symptoms and postoperative outcomes between cVS and sVS. RESULTS: There were a total of 315 patients (64% female; mean age, 54 yrs) and 46 (15%) were cystic. cVS were significantly larger than sVS (maximum diameter, 28 vs. 18 mm, p < 0.001) and had higher rates of dysphagia and dysphonia preoperatively (p < 0.02). cVSs were more likely to undergo translabyrinthine resection (76 vs. 50%, p = 0.001) and have a higher rate of subtotal resection (STR) compared with sVS (30 vs. 13%, p = 0.003). At latest follow-up, fewer cVS achieved good facial nerve (FN) outcome (House-Brackmann [HB] I/II) (80 vs. 90%, p = 0.048). Subanalysis of cVS and sVS matched in tumor size, and surgical approach did not show differences in the rate of STR or FN outcomes (HB I/II, 82 vs. 78%, p = 0.79). CONCLUSION: In this large multi-institutional series, cVSs represent a distinct entity and are characterized by larger tumor size and higher incidence of atypical symptoms. Although cVSs were more likely to undergo STR and portend worse FN outcomes than sVSs, this may be due to their larger tumor size rather than the presence of the cystic component.

PURPOSE: Understanding the complication profile of craniosynostosis surgery is important, yet little is known about complication co-occurrence in syndromic children after multi-suture craniosynostosis surgery. We examined concurrent perioperative complications and predictive factors in this population. METHODS: In this retrospective cohort study, children with syndromic diagnoses and multi-suture involvement who underwent craniosynostosis surgery in 2012-2020 were identified from the National Surgical Quality Improvement Program-Pediatric database. The primary outcome was concurrent complications; factors associated with concurrent complications were identified. Correlations between complications and patient outcomes were assessed. RESULTS: Among 5,848 children identified, 161 children (2.75%) had concurrent complications: 129 (2.21%) experienced two complications and 32 (0.55%) experienced ≥ 3. The most frequent complication was bleeding/transfusion (69.53%). The most common concurrent complications were transfusion/superficial infection (27.95%) and transfusion/deep incisional infection (13.04%) or transfusion/sepsis (13.04%). Two cardiac factors (major cardiac risk factors (odds ratio (OR) 3.50 [1.92-6.38]) and previous cardiac surgery (OR 4.87 [2.36-10.04])), two pulmonary factors (preoperative ventilator dependence (OR 3.27 [1.16-9.21]) and structural pulmonary/airway abnormalities (OR 2.89 [2.05-4.08])), and preoperative nutritional support (OR 4.05 [2.34-7.01]) were independently associated with concurrent complications. Children who received blood transfusion had higher odds of deep surgical site infection (OR 4.62 [1.08-19.73]; p = 0.04). CONCLUSIONS: Our results indicate that several cardiac and pulmonary risk factors, along with preoperative nutritional support, were independently associated with concurrent complications but procedural factors were not. This information can help inform presurgical counseling and preoperative risk stratification in this population.

Objective To explore the surgical treatment of depressed fracture of skull in neonates. Methods and Results Eight neonates with depressed fracture of skull who underwent surgery in Children's Hospital Affiliated to Shandong University from January 2021 to December 2023 were included, and all of them underwent CT thin-slice scan + 3D reconstruction of skull before surgery. According to the location, extent and depth of the depression, the depressed edge was drilled and the depressed skull was reduced by bone pry (3 cases). The depressed skull collapsed again after the bone was pried up, the skin incision was extended to reveal the depressed area, and the shaped absorbable connector was fixed in the depressed area after prying up (2 cases). Blunt separation of the skull and dura mater at the lateral corner of the anterior fontanelle, and deep bone pry to pry up the depressed skull for reduction (one case). The skull and dura mater were bluntly separated from the coronal suture at the edge of the depression, and the depressed skull was pried up and reduced by deep bone pry (2 cases). On the first day after surgery, the re- examination of CT thin-slice scan + 3D reconstruction of skull showed that the depression reduction was satisfactory. Spontaneous fracture healing was happened in one case with linear fractures; hemorrhage resorption spontaneously was happened in one case with epidural hematoma. The average follow-up was 6.80 months, and the re-examination of CT thin-slice scan + 3D reconstruction of skull showed that the skull development was normal and there was no re-depression. Conclusions Immediate reduction of depressed fracture of skull can be achieved with surgery, and for fractures close to the anterior fontanelle or suture, the depression can be prying up through the lateral angle of the anterior fontanelle or the unclosed suture, which is more minimally invasive.

Objective To review the effect of resection of pediaric craniopharyngioma and the long- term quality of life. Methods The clinical datas before, during and after operation of 30 pediatric craniopharyngioma patients who were operated in Xuanwu Hospital, Capital Medical University from March 2014 to June 2024 were collected for retrospective analysis. The Katz index, body mass index (BMI), as well as one's ability to paparticipate in normal school life and physical exercise at last follow - up were recorded as key factors of long - term quality of life assesement. Results There were 7 (23.33%) of pediatric craniopharyngioma patients were identified as obese, 19 (63.33%) patients had endocrine dysfunction and 30 (100%) were identified as Katz index grade A before operation. Total resection of the tumor was achieved in 29 cases, while one case had subtotal resection. Median follow-up time was 38.00 (17.25, 53.00) months. The number of obese children increased to 9 (30%) during the last follow-up, but showed no statistic significance (-2 = 0.125, P = 0.727). The number of patients with endocrine dysfunction increased to 27 (90%), and showed statistic significance (-2 = 4.083, P = 0.039). All 30 cases remained Katz index grade A during the last follow-up. During the last follow-up, only one patient hadn't return to normal school life and 2 patients couldn't join physical exercise in school after total resection of craniopharyngioma. Conclusions Total resection in pediatric craniopharyngioma patients can still achieve good prognosis, and should be the target of surgical treatment. [ABSTRACT FROM AUTHOR]

Flow diverter (FD) is increasingly used in the management of wide necked cerebral aneurysms. Despite a reported lower efficacy in middle cerebral artery (MCA) aneurysms, they are still being utilised. Microsurgery is best considered as an index treatment, but can also be a safe and effective treatment when encountering a persistent MCA aneurysm after prior FD. As there is a paucity in literature and more cases of failed FD are expected to appear, we want to add our experience to the existing literature. The microsurgical management of a persistent MCA bifurcation aneurysm, 3 years after a p48 MW HPC Flow Diverter (phenox GmbH, Bochum Germany) insertion is reported and the relevant literature discussed.

(1) Background: The transglabellar approach, a type of transfacial technique, typically involves glabellar resection and opening the frontal sinus via a bicoronal incision, providing access to the anterior cranial vault. To prevent complications, the frontal sinus is typically obliterated. However, the success of transnasal endoscopic techniques has prompted a re-evaluation of these traditional methods. (2) Methods: This paper provides a brief literature review and discusses the removal of an elongated glioma of the left gyrus rectus (4.4 × 1.9 × 2.2 cm) in a 63-year-old male using a transglabellar subfrontal approach via a butterfly incision, with frontal sinus preservation. (3) Results: An uneventful gross-total resection of a WHO grade II oligodendroglioma was achieved. There is a paucity of literature describing a transglabellar subfrontal approach via a butterfly incision with frontal sinus preservation. (4) Conclusions: The described approach could be utilized in selected cases such as small intra-axial lesions oriented longitudinally along the inferomedial frontal lobe from the posterior wall of the frontal sinus to the anterior communicating artery complex in patients with pre-existing glabellar rhytids. Since this is merely a case presentation, we cannot conclude that this represents established clinical practice. The outcomes of this approach should be investigated in the future.

Pediatric gliomas are highly heterogeneous and have unique molecular characteristics. They are not smaller versions of adult gliomas. This review emphasizes the basic points of surgery, radiotherapy, and chemotherapy for pediatric gliomas, introduces the similarities and differences with targeted therapy for adult gliomas, describes the important driver gene abnormalities involved in pediatric gliomas and the corresponding targeted therapy strategies, and focuses on the epigenetic treatment strategies for pediatric diffuse high-grade gliomas caused by histone H3 mutations, and looks forward to the future work of diagnosis and treatment of pediatric gliomas. [ABSTRACT FROM AUTHOR]

After recent updates to the World Health Organization pathological criteria for diagnosing and grading diffuse gliomas, all major North American and European neuro-oncology societies recommend a maximal safe resection as the initial management of a diffuse glioma. For neurosurgeons to achieve this goal, the surgical plan for both low- and high-grade gliomas should be to perform a supramaximal resection when feasible based on preoperative imaging and the patients performance status, utilizing every intraoperative adjunct to minimize postoperative neurological deficits. While the surgical approach and technique can vary, every effort must be taken to identify and preserve functional cortical and subcortical regions. In this summary statement on the current state of the field, we describe the tools and technologies that facilitate the safe removal of diffuse gliomas and highlight intraoperative and postoperative management strategies to minimize complications for these patients. Moreover, we discuss how surgical resections can go beyond cytoreduction by facilitating biological discoveries and improving the local delivery of adjuvant chemo- and radiotherapies.

Objective To investigate the application of exoscope in resection of parasagittal meningioma. Methods A retrospective analysis was conducted on 50 patients with parasagittal meningioma undergoing surgical treatment in a same medical group of our neurosurgical department from March 2021 to March 2023. According to their surgical procedures, they were divided into exoscope group (n=22) and microscope group (n=28). The surgical efficacy, surgical complications and surgical experience were compared between the 2 groups and analyzed. Results There were no significant differences between the 2 groups in terms of sex ratio (male/female: 10/12 vs 12/16), mean age (50.7±10.2 vs 52.3±11.1 years) and mean tumor size (20.79±25.04 vs 20.60±21.38 cm3). No statistical differences were observed in the duration of operation (217.73±59.66 vs 220.54±56.82 min), intraoperative blood loss (181.82±105.27 vs 189.29±103.06 mL), or total resection rate (90.9% vs 89.3%) between the 2 groups. Postoperative neurological dysfunction, infection rate and other complications also presented no notable differences between them. In the operation of parasagittal meningioma, exoscope can provide a larger view of the parasagittal sinus, such as the subdural border, which is difficult to be exposed by single microscope. Moreover, exoscope presented a higher level of comfort operating and better intraoperative teaching display compared to the surgical microscope. Conclusion For parasagittal meningiomas, exoscope is a safe and effective option, with similar surgical outcomes and postoperative complications as surgical microscope. What's more, exoscope presents more comfortable intraoperative ergonomic posture, higher surgical team participation, and better teaching effect.

Traumatic optic neuropathy (TON) is a rare that causes severe visual impairment usually results from cranial or ocular trauma. TON manifests directly and indirectly, which is more common. The incidence rate ranges from 0.7% to 2.5%. Clinical indicators of TON include the presence of an afferent pupillary defect after trauma, decreased vision acuity and intact ocular structure. Surgical decompression appears to be a feasible option in cases with direct bone compression on the optic nerve or progressive vision impairment in indirect TON. However, the evidence supporting treatment efficacy for improvement in vision is still ambiguous. This review will examine surgical techniques for decompressing the optic canal.

Treatment of neurosurgical intensive care patients infected with multidrug resistant (MDR) or extensive drug resistant (XDR) Acinetobacter baumannii presents significant challenges and is associated with high mortality rates. Sulbactam has long been an effective treatment for MDR Acinetobacter baumannii, particularly due to its ability to penetrate the inflamed blood -brain barrier, making it highly suitable for use in severe neurosurgical cases. However, in recent years, increasing resistance to sulbactam among Acinetobacter baumannii strains has become a concern. There is a lack of standardized guidelines regarding the dosage, administration methods, routes and combination therapy strategies for sulbactam in the treatment of these resistant infections. Thus, Chinese Neurosurgical Intensive Care Management Collaborative Group has developed the "Chinese expert consensus on the use of sulbactam to treat patients infected with Acinetobacter baumannii in the neurosurgical intensive care unit", through a thorough review of relevant evidence - based medical literature and extensive discussion and revision. This consensus includes 28 recommendations aimed at providing scientific and feasible clinical guidance for the application of sulbactam in the management of neurosurgical intensive care patients.

Objective To explore the efficacy of a novel and simple manual bone cone drilling hematoma drainage for hypertensive intracerebral hemorrhage. Methods From January 2021 to December 2022, 103 patients with hypertensive intracerebral hemorrhage at The Affiliated Bozhou Hospital of Anhui Medical University were included. They were treated with traditional bone cone drilling hematoma drainage (traditional group, n = 51) and novel-type bone cone drilling hematoma drainage (novel-type group, n = 52). Based on pre- and post-surgery head CT results, the hematoma clearance rate and accuracy of catheter placement were calculated. National Institutes of Health Stroke Scale (NIHSS) was used to assess the severity of neurological deficits, and modified Rankin Scale (mRS) was used to evaluate the neurological functional prognosis. Results The hematoma clearance rate in the novel-type group [(45.54 ± 24.23)% vs. (35.08 ± 6.49)%; t = 3.008, P = 0.004] and the accuracy of catheter placement [90.38% (47/52) vs. 68.63% (35/51); χ2 = 7.509, P = 0.006] were significantly higher than those of the traditional group. The novel-type group and the traditional group showed statistically significant differences in hematoma volume (F = 9.157, P = 0.003) and mRS score (F = 4.412, P = 0.038). The postoperative hematoma volume (t = - 4.625, P = 0.000) and mRS score (t = - 2.712, P = 0.008) of the novel-type group were lower than those of the traditional group. Statistically significant differences were observed in hematoma volume (F = 280.635, P = 0.000), NIHSS score (F = 443.320, P = 0.000) and mRS score (F = 552.781, P = 0.000) before and after surgery in the 2 groups; the hematoma volume (t = 10.233, P = 0.000; t = 19.906, P = 0.000), NIHSS score (t = 14.576, P = 0.000; t = 15.286, P = 0.000) and mRS score (t = 20.201, P = 0.000; t = 13.511, P = 0.000) after operation were lower than those before operation in the 2 groups. Conclusions The novel and simple manual bone cone drilling hematoma drainage is a safe and effective treatment for hypertensive intracerebral hemorrhage.

Objective To investigate and compare the efficacy of endoscopic-assisted hematoma evacuation and burr hole hematoma drainage combined with urokinase in the treatment of septated chronic subdural hematoma (CSDH). Methods A total of 38 patients with septated CSDH who were admitted in Peking Union Medical College Hospital and received endoscopic-assisted hematoma evacuation (endoscopy group, n = 19) or burr hole drainage combined with urokinase (burr hole group, n = 19) from January 2022 to December 2023. The change rate of the hematoma cavity was calculated, the modified Rankin Scale (mRS) and Barthel Index (BI) were used to evaluate neurological function prognosis and abilities of daily living. In addition, postoperative drainage time, postoperative hospitalization time, total hospitalization cost and incidence of cerebrospinal fluid leakage were recorded. Results The two treatment modalities did not show differences in the change rate of the hematoma cavity (t = 0.858, P = 0.396). Both endoscopy group (Z = - 4.116, P = 0.000) and burr hole group (Z = - 4.195, P = 0.000) had lower mRS scores on discharge than on admission, while the difference between the 2 groups on discharge was not significant (Z = - 0.502, P = 0.616). The endoscopy group (Z = - 1.557, P = 0.119) and burr hole group (Z = - 0.091, P = 0.928) had no significant difference in BI scores on discharge versus on admission, and the difference in BI scores between the 2 groups on discharge was also not statistically significant (Z = - 0.853, P = 0.394). Postoperative drainage time was longer in the endoscopy group (t = - 2.488, P = 0.018), but postoperative hospitalization time was longer in the burr hole group (t = - 3.894, P = 0.000). Total hospitalization cost in both 2 groups (t = 1.175, P = 0.248) and the incidence of cerebrospinal fluid leakage (Fisher's exact probability: P = 0.313) were not statistically significant. Conclusions Both neuroendoscopic surgery and burr hole drainage combined with urokinase treatment are safe and effective in treating septated CSDH. They can clear the hematoma and improve neurological function; neuroendoscopic surgery can faster improve the neurological function and shorter postoperative hospitalization time.

Introduction. Intravascular papillary endothelial hyperplasia is an unusual reactive proliferation of endothelial cells around an organized thrombus, which occurs either in a dilated blood vessel, hematoma, or preexisting vascular lesion. These tumors rarely affect the central nervous system. Symptoms depend on the localization of the process itself. Localization in the central nervous system is limited to the intracranial space. Localization in the spinal canal is extremely rare, and only a few clinical cases have been described so far in the literature. Case report. A 67-year-old female patient was examined neurologically initially due to bilateral weakness of the lower extremities, accompanied by a feeling of pain and muscle tension, dominantly in the upper legs, more to the right. The complaints were present a year ago, and before that period, the patient was in a stable state of health. Due to a severe neurological deficit and the need for detailed exploration, the patient was hospitalized. A diagnosis was performed, which showed the localization of the pathological process in the thoracic 5-6 region of the spinal column. Decompression surgery was performed, and with the ex tempore findings metastasis was ruled out. Definitive pathohistological findings proved Masson's tumor. After the operation, the neurological weakness recovered. Conclusion. Masson's tumor, although rarely localized in spinal canal, is curable if it is correctly diagnosed and if an adequate therapeutic approach is applied. The initially presented symptoms may resemble numerous neurological or systemic diseases, which requires the clinician to be continuously aware of such rare pathological processes.

Intradural spinal metastases significantly impair neurological function and quality of life, necessitating multimodal, palliative management to preserve mobility and alleviate pain. The effectiveness of systemic chemotherapy and radiotherapy is limited due to the blood-spinal cord barrier and the tumours' radioresistance, respectively. This highlights the urgency for alternative treatments given the rapid neurological decline. Surgical intervention becomes crucial, focusing on maximum tumour debulking to enhance disease control, restore ambulation, and palliate symptoms without compromising neurological function. Achieving this involves meticulous preoperative planning and aggressive intraoperative neuromonitoring. Combining surgery with adjuvant therapies may improve local control and potentially delay recurrence. This case-based review emphasizes the surgical considerations and outcomes in two cases of intradural spinal metastases, underscoring the value of surgery in multimodal therapy.

Treatment of neurosurgical intensive care patients infected with multidrug resistant (MDR) or extensive drug resistant (XDR) Acinetobacter baumannii presents significant challenges and is associated with high mortality rates. Sulbactam has long been an effective treatment for MDR Acinetobacter baumannii, particularly due to its ability to penetrate the inflamed blood -brain barrier, making it highly suitable for use in severe neurosurgical cases. However, in recent years, increasing resistance to sulbactam among Acinetobacter baumannii strains has become a concern. There is a lack of standardized guidelines regarding the dosage, administration methods, routes and combination therapy strategies for sulbactam in the treatment of these resistant infections. Thus, Chinese Neurosurgical Intensive Care Management Collaborative Group has developed the "Chinese expert consensus on the use of sulbactam to treat patients infected with Acinetobacter baumannii in the neurosurgical intensive care unit", through a thorough review of relevant evidence-based medical literature and extensive discussion and revision. This consensus includes 28 recommendations aimed at providing scientific and feasible clinical guidance for the application of sulbactam in the management of neurosurgical intensive care patients.

We aimed to retrospectively determine the resection rate of fluid-attenuated inversion recovery (FLAIR) lesions to evaluate the clinical effects of supramaximal resection (SMR) on the survival of patients with glioblastoma (GBM). Thirty-three adults with newly diagnosed GBM who underwent gross total tumor resection were enrolled. The tumors were classified into cortical and deep-seated groups according to their contact with the cortical gray matter. Pre- and postoperative FLAIR and gadolinium-enhanced T1-weighted imaging tumor volumes were measured using a three-dimensional imaging volume analyzer, and the resection rate was calculated. To evaluate the association between SMR rate and outcome, we subdivided patients whose tumors were totally resected into the SMR and non-SMR groups by moving the threshold value of SMR in 10% increments from 0% and compared their overall survival (OS) change. An improvement in OS was observed when the threshold value of SMR was 30% or more. In the cortical group (n = 23), SMR (n = 8) tended to prolong OS compared with gross total resection (GTR) (n = 15), with the median OS of 69.6 and 22.1 months, respectively (p = 0.0945). Contrastingly, in the deep-seated group (n = 10), SMR (n = 4) significantly shortened OS compared with GTR (n = 6), with median OS of 10.2 and 27.9 months, respectively (p = 0.0221). SMR could help prolong OS in patients with cortical GBM when 30% or more volume reduction is achieved in FLAIR lesions, although the impact of SMR for deep-seated GBM must be validated in larger cohorts.

OBJECTIVE: Resection of brain metastases (BMs) may be associated with increased risk of leptomeningeal disease (LMD). This study examined rates and predictors of LMD, including imaging subtypes, in patients who underwent resection of a BM followed by postoperative radiation. METHODS: A retrospective, single-center study was conducted examining overall LMD, classic LMD (cLMD), and nodular LMD (nLMD) risk. Logistic regression, Cox proportional hazards, and random forest analyses were performed to identify risk factors associated with LMD. RESULTS: Of the 217 patients in the cohort, 47 (21.7%) developed postoperative LMD, with 19 cases (8.8%) of cLMD and 28 cases (12.9%) of nLMD. Six-, 12-, and 24-month LMD-free survival rates were 92.3%, 85.6%, and 71.4%, respectively. Patients with cLMD had worse survival outcomes from the date of LMD diagnosis compared with nLMD (median 2.4 vs 6.9 months, p = 0.02, log-rank test). Cox proportional hazards analysis identified cerebellar/insular/occipital location (hazard ratio [HR] 3.25, 95% confidence interval [CI] 1.73-6.11, p = 0.0003), absence of extracranial disease (HR 2.49, 95% CI 1.27-4.88, p = 0.008), and ventricle contact (HR 2.82, 95% CI 1.5-5.3, p = 0.001) to be associated with postoperative LMD. A predictive model using random forest analysis with an area under the receiver operating characteristic curve of 0.87 in a test cohort identified tumor location, systemic disease status, and tumor volume as the most important factors associated with LMD. CONCLUSIONS: Tumor location, absence of extracranial disease at the time of surgery, ventricle contact, and increased tumor volume were associated with LMD. Further work is needed to determine whether escalating therapies in patients at risk of LMD prevents disease dissemination.

IntroductionThe purpose of this study is to provide a state-of-the-art review regarding risk factors for perioperative complications in adult spinal deformity (ASD) surgery. The review includes levels of evidence for risk factors associated with complications in ASD surgery.MethodsUsing the PubMed database, we searched for complications, risk factors, and adult spinal deformity. The included publications were assessed for level of evidence as described in clinical practice guidelines published by the North American Spine Society, with summary statements generated for each risk factor (Bono et al. in Spine J 9:1046-1051, 2009).ResultsFrailty had good evidence (Grade A) as a risk for complications in ASD patients. Fair evidence (Grade B) was assigned for bone quality, smoking, hyperglycemia and diabetes, nutritional status, immunosuppression/steroid use, cardiovascular disease, pulmonary disease, and renal disease. Indeterminate evidence (Grade I) was assigned for pre-operative cognitive function, mental health, social support, and opioid utilization.ConclusionsIdentification of risk factors for perioperative complications in ASD surgery is a priority for empowering informed choices for patients and surgeons and managing patient expectations. Risk factors with grade A and B evidence should be identified prior to elective surgery and modified to reduce the risk of perioperative complications.

Healthcare-associated central nervous system infections are a significant complication for patients undergoing neurosurgical interventions. We present a case of a 6-year-old patient with an embryonal tumor of the central nervous system. Following a craniotomy for the resection of the tumor, an external ventricular drainage was placed. Several weeks after surgery, she developed signs of meningism. Cerebrospinal fluid cultures were positive for pan-drug resistant Acinetobacter baumannii. Several revisions with the insertion of new external valves were done. She was treated with intravenously meropenem and vancomycin combined with colistin administrated intraventricularly. Significant improvement was seen clinically with negative cultures after 2 weeks. The synergistic action of colistin administrated locally combined with systemic antibiotics may be a promising option for critically ill patients with pan-drug resistant A. baumannii central nervous system infection.

BackgroundTerminology to describe extent of resection in glioblastoma is inconsistent across clinical trials. A surgical classification system was previously proposed based upon residual contrast-enhancing (CE) tumor. We aimed to (1) explore the prognostic utility of the classification system and (2) define how much removed non-CE tumor translates into a survival benefit.MethodsThe international RANO resect group retrospectively searched previously compiled databases from 7 neuro-oncological centers in the USA and Europe for patients with newly diagnosed glioblastoma per WHO 2021 classification. Clinical and volumetric information from pre- and postoperative MRI were collected.ResultsWe collected 1,008 patients with newly diagnosed IDHwt glioblastoma. 744 IDHwt glioblastomas were treated with radiochemotherapy per EORTC-26981/22981 (TMZ/RT→TMZ) following surgery. Among these homogenously treated patients, lower absolute residual tumor volumes (in cm3) were favorably associated with outcome: patients with "maximal CE resection" (class 2) had superior outcome compared to patients with "submaximal CE resection" (class 3) or "biopsy" (class 4). Extensive resection of non-CE tumor (≤5 cm3 residual non-CE tumor) was associated with better survival among patients with complete CE resection, thus defining class 1 ("supramaximal CE resection"). The prognostic value of the resection classes was retained on multivariate analysis when adjusting for molecular and clinical markers.ConclusionsThe proposed "RANO categories for extent of resection in glioblastoma" are highly prognostic and may serve for stratification within clinical trials. Removal of non-CE tumor beyond the CE tumor borders may translate into additional survival benefit, providing a rationale to explicitly denominate such "supramaximal CE resection."

ObjectiveDespite advances in the treatment of psychiatric diseases, currently available therapies do not provide sufficient and durable relief for as many as 30-40% of patients. Neuromodulation, including deep brain stimulation (DBS), has emerged as a potential therapy for persistent disabling disease, however it has not yet gained widespread adoption. In 2016, the American Society for Stereotactic and Functional Neurosurgery (ASSFN) convened a meeting with leaders in the field to discuss a roadmap for the path forward. A follow-up meeting in 2022 aimed to review the current state of the field and to identify critical barriers and milestones for progress.DesignThe ASSFN convened a meeting on June 3, 2022 in Atlanta, Georgia and included leaders from the fields of neurology, neurosurgery, and psychiatry along with colleagues from industry, government, ethics, and law. The goal was to review the current state of the field, assess for advances or setbacks in the interim six years, and suggest a future path forward. The participants focused on five areas of interest: interdisciplinary engagement, regulatory pathways and trial design, disease biomarkers, ethics of psychiatric surgery, and resource allocation/prioritization. The proceedings are summarized here.ConclusionThe field of surgical psychiatry has made significant progress since our last expert meeting. Although weakness and threats to the development of novel surgical therapies exist, the identified strengths and opportunities promise to move the field through methodically rigorous and biologically-based approaches. The experts agree that ethics, law, patient engagement, and multidisciplinary teams will be critical to any potential growth in this area.

PurposeIn patients with diffuse low-grade glioma (LGG), the extent of surgical tumor resection (EOR) has a controversial role, in part because a randomized clinical trial with different levels of EOR is not feasible.MethodsIn a 20-year retrospective cohort of 392 patients with IDH-mutant grade 2 glioma, we analyzed the combined effects of volumetric EOR and molecular and clinical factors on overall survival (OS) and progression-free survival by recursive partitioning analysis. The OS results were validated in two external cohorts (n = 365). Propensity score analysis of the combined cohorts (n = 757) was used to mimic a randomized clinical trial with varying levels of EOR.ResultsRecursive partitioning analysis identified three survival risk groups. Median OS was shortest in two subsets of patients with astrocytoma: those with postoperative tumor volume (TV) > 4.6 mL and those with preoperative TV > 43.1 mL and postoperative TV ≤ 4.6 mL. Intermediate OS was seen in patients with astrocytoma who had chemotherapy with preoperative TV ≤ 43.1 mL and postoperative TV ≤ 4.6 mL in addition to oligodendroglioma patients with either preoperative TV > 43.1 mL and residual TV ≤ 4.6 mL or postoperative residual volume > 4.6 mL. Longest OS was seen in astrocytoma patients with preoperative TV ≤ 43.1 mL and postoperative TV ≤ 4.6 mL who received no chemotherapy and oligodendroglioma patients with preoperative TV ≤ 43.1 mL and postoperative TV ≤ 4.6 mL. EOR ≥ 75% improved survival outcomes, as shown by propensity score analysis.ConclusionAcross both subtypes of LGG, EOR beginning at 75% improves OS while beginning at 80% improves progression-free survival. Nonetheless, maximal resection with preservation of neurological function remains the treatment goal. Our findings have implications for surgical strategies for LGGs, particularly oligodendroglioma.

PurposeSpheno-orbital meningiomas are rare tumors, accounting for up to 9% of all intracranial meningiomas. Patients commonly present with proptosis, and visual deficits. These slow growing tumors are hard to resect due to extension into several anatomical compartments, resulting in recurrence rates as high as 35-50%. Although open surgical approaches have been historically used for resection, a handful of endoscopic approaches have been reported in recent years. We aimed to review the literature and describe a case of spheno-orbital meningioma with severe vision loss which was resected with an endoscopic endonasal approach achieving complete resolution of visual symptoms.MethodsA systematic review of literature was conducted in accordance with the PRISMA guidelines. PubMed, Cochrane, and Web of Science databases were queried for spheno-orbital meningiomas resected via an endoscopic endonasal approach. Furthermore, the presentation, surgical management, and post-operative outcomes of a 53-year-old female with a recurrent spheno-orbital meningioma are described.ResultsThe search yielded 26 articles, of which 8 were included, yielding 19 cases. Average age at presentation was 60.5 years (range: 44-82), and 68.4% of patients were female. More than half of the cases achieved subtotal resection. Common complications associated with endoscopic endonasal surgery included CN V2 or CN V2/V3 hypoesthesia. Following surgical intervention, visual acuity and visual field remained stable or improved in the majority of the patients.ConclusionEndoscopic approaches are slowly gaining momentum for treatment of spheno-orbital meningiomas. Further studies on the clinical benefits of this approach on patient outcomes and post-operative complications is warranted.

Management of chronic subdural hematoma (cSDH) poses unique challenges and can be fraught with complications. Understanding the spatial relationships of cSDH to adjacent brain tissue and skull topography is critical for successful surgical treatment. The aim of this report is to highlight the feasibility and efficacy of a novel augmented reality (AR) overlay tool for surgical planning with technical description of two surgical cases using AR for surgical management of cSDH. This report describes a fiducial-less AR system for surgical planning of surgical evacuation of cSDH. The AR system was used to superimpose 3D anatomy onto the patients head to provide image guidance during two cases of evacuation. Imaging demonstrated convexity cSDH. A 3D model of the patient's anatomy was created and registered onto the patients' heads using a novel AR system. Surgical evacuation of the cSDH was completed in each case with surgical planning assisted by AR overlay. [ABSTRACT FROM AUTHOR]

Study Design: : Retrospective Chart Review. Objectives: Incidental durotomies (IDs) are common spine surgery complications. In this study, we present a review on the most commonly utilized management strategies, report our institutional experience with case examples, and describe a stepwise management algorithm. Methods: A retrospective review was performed of the electronic medical records of all patients who underwent a thoracolumbar or lumbar spine surgery between March 2017 and September 2019. Additionally, a literature review of the current management approaches to treat IDs and persistent postoperative CSF leaks following lumbar spine surgeries was performed. Results: We looked at 1133 patients that underwent posterior thoracolumbar spine surgery. There was intraoperative evidence of ID in 116 cases. Based on our cohort and the current literature, we developed a progressive treatment algorithm for IDs that begins with a primary repair, which can be bolstered by dural sealants or a muscle patch. If this fails, the primary repair can be followed by a paraspinal muscle flap, as well as a lumbar drain. If the patient cannot be weaned from temporary CSF diversion, the final step in controlling postoperative leak is longterm CSF diversion via a lumboperitoneal shunt. In our experience, these shunts can be weaned once the patient has no further clinical or radiographic signs of CSF leak. Conclusions: There is no standardized management approach of IDs and CSF leaks in the literature. This article intends to provide a progressive treatment algorithm and contribute to the development process of a treatment consensus. [ABSTRACT FROM AUTHOR]

Pressure injuries are a significant concern for patients undergoing neurosurgical procedures due to prolonged immobility and the complexity of care. This study evaluates the efficacy of standardized pressure ulcer management protocols in preventing pressure injuries and enhancing patient care in a neurosurgical context. A comprehensive retrospective analysis was conducted at a single institution from December 2020 to December 2023, comparing 50 patients who received standardized pressure ulcer management (intervention group) with 50 patients who received conventional care (control group). The study assessed the incidence of pressure ulcers, patient comfort levels using the Kolcaba Comfort Scale and sleep quality using the Richards‐Campbell Sleep Questionnaire (RCSQ). Statistical analysis was performed using SPSS software, version 27.0, applying t‐tests and chi‐square tests as appropriate. The intervention group exhibited a significantly lower incidence of pressure ulcers at all measured time points post‐surgery compared to the control group. Patient comfort levels in the intervention group were consistently higher across psychological, environmental, physiological and socio‐cultural domains. Sleep quality metrics, including sleep depth, latency to sleep onset and overall sleep quality, were significantly improved in the intervention group. The implementation of standardized pressure ulcer management protocols in neurosurgical care significantly reduces the incidence of pressure injuries, enhances patient comfort and improves sleep quality. These findings highlight the importance of adopting structured care protocols to improve postoperative outcomes and patient well‐being in neurosurgical settings. [ABSTRACT FROM AUTHOR]

Glossopharyngeal neuralgia is a rare condition characterized by pain along the distribution of the glossopharyngeal nerve. Surgical approaches via microvascular decompression represent a common treatment strategy. For this procedure, an understanding of the location of the cranial nerve and the offending vasculature is critically important. A mixed reality system was used to register patient-specific 3D models onto the patients head for operative planning and anatomical visualization. A 58-year-old female presented to neurosurgery with severe right-sided facial, tongue, and jaw pain unresponsive to multiple conservative therapies including medication. T2-weighted MRI with FIESTA sequence demonstrated right posterior inferior communicating artery compression of the right glossopharyngeal nerve entry zone. An augmented reality system was used to visualize the patients' anatomy overlaid onto the patients' head. A microvascular decompression of Cranial Nerves IX and X was performed via a retrosigmoid approach. Patient obtained significant relief of preoperative pain symptoms without complications.

Background: The rapid evolution of neuroendovascular intervention has resulted in the inclusion of endovascular techniques as a core competency in neurosurgical residency training. Methods: We conducted a literature review of studies involving the training of neurosurgical residents in cerebrovascular and endovascular neurosurgery. We reviewed the evolution of cerebrovascular neurosurgery and the effects of these changes on residency, and we propose interventions to supplement contemporary training. Results: A to tal of 48 studies were included for full review. Studies evaluated trainee education and competency (29.2%, 14/48), neuroendovascular training models (20.8%, 10/48), and open cerebrovascular training models (52.1%, 25/48), with some overlap. We used a qualitative analysis of reviewed reports to generate a series of suggested training supplements to optimize cerebrovascular education. Conclusion: Cerebrovascular neurosurgery is at a crossroads where trainees must develop disparate skill sets with inverse trends in volume. Continued longitudinal exposure to both endovascular and open cerebrovascular surgical fields should be mandated in general resident education, and blended learning tactics using adjunct simulation systems and models should be incorporated with didactics to both optimize learning and alleviate restraints placed by decreased volume and autonomy.

Brain metastases occur in almost one-third of adult patients with solid tumor malignancies and lead to considerable patient morbidity and mortality. The rising incidence of brain metastases has been ascribed to the development of better imaging and screening techniques and the formulation of better systemic therapies. Until recently, the multimodal management of brain metastases focused primarily on the utilization of neurosurgical techniques, with varying combinations of whole-brain radiation therapy and stereotactic radio-surgical procedures. Over the past 2 decades, in particular, the increment in knowledge pertaining to molecular genetics and the pathogenesis of brain metastases has led to significant developments in targeted therapies and immunotherapies. This review article highlights the recent updates in the management of brain metastases with an emphasis on novel systemic therapies.

Intraoperative neuromonitoring (IONM) is a widely used practice in spine surgery for early detection and minimization of neurological injury. IONM is most commonly conducted by indirectly recording motor and somatosensory evoked potentials from either muscles or the scalp, which requires large-amplitude electrical stimulation and provides limited spatiotemporal information. IONM may inform of inadvertent events during neurosurgery after they occur, but it does not guide safe surgical procedures when the anatomy of the diseased spinal cord is distorted. To overcome these limitations and to increase our understanding of human spinal cord neurophysiology, we applied a microelectrode array with hundreds of channels to the exposed spinal cord during surgery and resolved spatiotemporal dynamics with high definition. We used this method to construct two-dimensional maps of responsive channels and define with submillimeter precision the electrophysiological midline of the spinal cord. The high sensitivity of our microelectrode array allowed us to record both epidural and subdural responses at stimulation currents that are well below those used clinically and to resolve postoperative evoked potentials when IONM could not. Together, these advances highlight the potential of our microelectrode arrays to capture previously unexplored spinal cord neural activity and its spatiotemporal dynamics at high resolution, offering better electrophysiological markers that can transform IONM.

Atherosclerosis, a chronic inflammatory disease of the arterial wall, serves as the pathophysiological basis for ischemic stroke and coronary heart disease, and stands as the primary cause of cardiovascular and cerebrovascular comorbidity. Both the heart and brain share similar risk factors, including hypertension, hyperlipidemia and diabetes, and so on. Furthermore, most patients with cardiovascular and cerebrovascular comorbidity experience more severe disease and poorer prognosis. This article comprehensively reviews research progress in the pathophysiology of cardiovascular and cerebrovascular comorbidity, their related risk factors, and proposes the strategies of "synchronous treatment for brain and heart" to offer new insights for the prevention and management of cardiovascular and cerebrovascular comorbidity.

Cardiovascular and cerebrovascular diseases are one of the most common cause of death in the world, atherosclerosis is the main pathologic change, and often involving cardiovascular and cerebrovascular concurrently. No consensus has been reached on whether carotid endarterectomy (CEA) combined with coronary artery bypass grafting (CABG) should be performed at concurrent operation or staged operation (CEA after CABG or CABG after CEA) in patients with ischemic cardiovascular and cerebrovascular diseases. However, with the deepening of research on cardiovascular and cerebrovascular diseases, the improvement of surgical techniques and development of intravascular intervention techniques, it provides theoretical basis and technical support for simultaneous surgical intervention.

Cardiovascular and cerebrovascular diseases are homologous diseases and can be comorbidities. Atherosclerosis is the pathological basis of the comorbidities of cardiovascular and cerebrovascular diseases. In recent years, with the improvement of surgical technique and the progress of drug intervention, the synchronous surgical treatment for brain and heart of cardiovascular and cerebrovascular diseases can improve clinical outcome. This article reviews the synchronous surgical treatment for brain and heart of cardiovascular and cerebrovascular diseases, in order to provide theoretical basis and clinical guidance for the cardiovascular and cerebrovascular diseases.

PurposeGliomas are the most common primary tumors of the central nervous system and are categorized by the World Health Organization into either low-grade (grades 1 and 2) or high-grade (grades 3 and 4) gliomas. A subset of patients with glioma may experience no tumor-related symptoms and be incidentally diagnosed. These incidental low-grade gliomas (iLGG) maintain controversial treatment course despite scientific advancements. Here we highlight the recent advancements in classification, neuroimaging, and surgical management of these tumors.MethodsA review of the literature was performed. The authors created five subtopics of focus: histological criteria, diagnostic imaging, surgical advancements, correlation of surgical resection and survival outcomes, and clinical implications.ConclusionsAlternating studies suggest that these tumors may experience higher mutational rates than their counterparts. Significant progress in management of gliomas, regardless of the grade, has been made through modern neurosurgical treatment modalities, diagnostic neuroimaging, and a better understanding of the genetic composition of these tumors. An optimal treatment approach for patients with newly diagnosed iLGG remains ill-defined despite multiple studies arguing in favor of safe maximal resection. Our review emphasizes the not so benign nature of incidental low grade glioma and further supports the need for future studies to evaluate survival outcomes following surgical resection.

Background: Unilateral percutaneous balloon kyphoplasty (PBK) is increasingly utilized for the management of osteoporotic vertebral compression fractures (OVCFs). Its potential advantages include procedural simplicity, reduced tissue trauma, and minimal radiation exposure. Case Description: A 59-year-old female with osteoporosis presented with back pain but was neurologically intact 2 weeks after a fall. The magnetic resonance imaging documented a thoracic 12 vertebral compression fracture that was successfully treated with a unilateral PBK. Conclusion: Unilateral PBK appears promising for managing OVCFs in the aging population and offers rapid pain relief, vertebral height restoration, and functional improvement. [ABSTRACT FROM AUTHOR]

BACKGROUND: Few data on the management of acute phase of traumatic spinal cord injury (tSCI) in patients suffering polytrauma are available. As the therapeutic choices in the first hours may have a deep impact on outcome of tSCI patients, we conducted an international survey investigating this topic. METHODS: The survey was composed of 29 items. The main endpoints of the survey were to examine: (1) the hemodynamic and respiratory management, (2) the coagulation management, (3) the timing of magnetic resonance imaging (MRI) and spinal surgery, (4) the use of corticosteroid therapy, (5) the role of intraspinal pressure (ISP)/spinal cord perfusion pressure (SCPP) monitoring and (6) the utilization of therapeutic hypothermia. RESULTS: There were 171 respondents from 139 centers worldwide. A target mean arterial pressure (MAP) target of 80-90 mmHg was chosen in almost half of the cases [n = 84 (49.1%)]. A temporary reduction in the target MAP, for the time strictly necessary to achieve bleeding control in polytrauma, was accepted by most respondents [n = 100 (58.5%)]. Sixty-one respondents (35.7%) considered acceptable a hemoglobin (Hb) level of 7 g/dl in tSCI polytraumatized patients. An arterial partial pressure of oxygen (PaO2) of 80-100 mmHg [n = 94 (55%)] and an arterial partial pressure of carbon dioxide (PaCO2) of 35-40 mmHg [n = 130 (76%)] were chosen in most cases. A little more than half of respondents considered safe a platelet (PLT) count > 100.000/mm3 [n = 99 (57.9%)] and prothrombin time (PT)/activated partial thromboplastin time (aPTT)

ObjectiveThe aim was to compare the outcomes of subdural electrode (SDE) implantations versus stereotactic electroencephalography (SEEG), the 2 predominant methods of intracranial electroencephalography (iEEG) performed in difficult-to-localize drug-resistant focal epilepsy.MethodsThe Surgical Therapies Commission of the International League Against Epilepsy created an international registry of iEEG patients implanted between 2005 and 2019 with ≥1 year of follow-up. We used propensity score matching to control exposure selection bias and generate comparable cohorts. Study endpoints were: (1) likelihood of resection after iEEG; (2) seizure freedom at last follow-up; and (3) complications (composite of postoperative infection, symptomatic intracranial hemorrhage, or permanent neurological deficit).ResultsTen study sites from 7 countries and 3 continents contributed 2,012 patients, including 1,468 (73%) eligible for analysis (526 SDE and 942 SEEG), of whom 988 (67%) underwent subsequent resection. Propensity score matching improved covariate balance between exposure groups for all analyses. Propensity-matched patients who underwent SDE had higher odds of subsequent resective surgery (odds ratio [OR] = 1.4, 95% confidence interval [CI] 1.05, 1.84) and higher odds of complications (OR = 2.24, 95% CI 1.34, 3.74; unadjusted: 9.6% after SDE vs 3.3% after SEEG). Odds of seizure freedom in propensity-matched resected patients were 1.66 times higher (95% CI 1.21, 2.26) for SEEG compared with SDE (unadjusted: 55% seizure free after SEEG-guided resections vs 41% after SDE).InterpretationIn comparison to SEEG, SDE evaluations are more likely to lead to brain surgery in patients with drug-resistant epilepsy but have more surgical complications and lower probability of seizure freedom. This comparative-effectiveness study provides the highest feasible evidence level to guide decisions on iEEG. ANN NEUROL 2021;90:927-939.

The ventriculoperitoneal shunt procedure represents a frequently conducted neurosurgical intervention; nevertheless, it harbors inherent risks that can precipitate complications in patients. Intestinal perforation accompanied by distal shunt protrusion through the anus is an uncommon phenomenon, observed in ~0.1% to 0.7% of cases, with mortality rates reaching up to 15%. Timely identification and comprehensive management of such complications are imperative to prevent further deterioration of the patient's condition. Herein, we present a case involving a 1-month-old female infant who presented with a tube protruding from the anal orifice. Immediate surgical intervention was undertaken to remove the distal shunt and prevent further infection in the patient. [ABSTRACT FROM AUTHOR]

Intrinsic brain tumors often occur within functional neural networks, leading to neurological impairment and disability of varying degrees. Advances in our understanding of tumor-network integration, human cognition and language processing, and multiparametric imaging, combined with refined intraoperative tumor resection techniques, have enhanced surgical management of intrinsic brain tumors within eloquent areas. However, cognitive symptoms impacting health-related quality of life, particularly processing speed, attention, concentration, working memory, and executive function, often persist after the postoperative recovery period and treatment. Multidisciplinary cognitive rehabilitation is the standard of care for addressing cognitive impairments in many neurological diseases. There is promising research to support the use of cognitive rehabilitation in adult brain tumor patients. In this review, we summarize the history and usefulness of postacute cognitive rehabilitation for adult brain tumor patients.
