Surgeons frequently experience physical strain due to fixed postures during long procedures, contributing to work-related musculoskeletal disorders. This technical note reports on the first clinical use of an AR headset during convexity meningioma resection.Methods: An 82-year-old female patient underwent surgical resection of a left convexity meningioma using an AR visualization system (Leica MyVeo). The headset displayed the microscope feed directly into the surgeon's and assistant's field of view, allowing both to maintain ergonomic postures throughout the operation. A post-procedural questionnaire and rapid entire body assessment (REBA) scores were used to evaluate ergonomics and workflow.Results: The AR headset was rated positively for improving team coordination and visualization continuity. Both surgeon and assistant reported increased comfort and reduced strain during the procedure. REBA scores indicated low ergonomic risk (3 for the surgeon, 2 for the assistant), suggesting an improvement over typical scores reported for microscope-based surgery. The tumor was completely resected without complications, and the patient had an uneventful postoperative course.Conclusion: This initial experience demonstrates that AR headsets can be safely integrated into neurosurgical workflows, offering significant ergonomic and collaborative advantages. These findings support further investigation into AR-assisted visualization as a complementary tool to traditional operative microscopy.","PeriodicalId":94217,"journal":{"name":"Surgical neurology international","volume":"16 ","pages":"362"},"PeriodicalIF":0.0,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12482705/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145208675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patient with high risk of recurring strokes despite standard medication therapy usually needs aggressive medical treatment such as self-expanding and balloon-expandable stents. Drug-eluting stents (DESs), with anti-vascular endothelial cell proliferation drugs, aim to inhibit smooth muscle cells proliferation and migration, providing a promising alternative to standard bare metal stents (BMS). This study compared the advantages and safety of DES to BMS in symptomatic ICAS patients.Methods: A comprehensive search was conducted through PubMed, Cochrane Central Register of Controlled Trials, and Science Direct in May 2024, adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Randomized trials comparing DES and BMS for symptomatic intracranial and vertebral artery stenosis were included in the study. Meta-analysis was carried out by RevMan software to analyze and odds ratio (OR) for primary and secondary outcomes.Results: Three randomized controlled trials (n = 491) were included in the study. DES significantly reduced instent restenosis (ISR) compared to BMS (OR 0.26, 95% confidence interval [CI]: 0.16-0.45, P < 0.00001) and lowered the risk of ischemic stroke in the target vessel (OR 0.20, 95% CI: 0.06-0.65, P = 0.008). No significant difference was observed in all-cause mortality (OR 0.80, 95% CI: 0.21-3.02, P = 0.74) or technical success rates. Symptomatic ISR within 1 year was markedly lower with DES (OR 0.09, 95% CI: 0.01-0.73, P = 0.02).Conclusion: Intravascular DES is more effective than BMS in lowering risk of ISR and incidence of ischemic stroke in symptomatic ICAS.","PeriodicalId":94217,"journal":{"name":"Surgical neurology international","volume":"16 ","pages":"363"},"PeriodicalIF":0.0,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12482777/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145208765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It provides neurosurgeons with a wider surgical field, good visibility of perforating branches, and ease of securing parent vessels; however, it has several disadvantages. Thus, in this study, we reviewed the efficacy of surgical clipping using the mini-anterior IH (AIH) approach for AcomA aneurysms in preserving olfactory nerve function.Methods: In this retrospective study, we evaluated the data of 12 consecutive patients with unruptured AcomA aneurysms who underwent surgical clipping using the mini-AIH approach between April 2012 and April 2025 at our hospital. We assessed the anatomical features of the aneurysms, complications associated with clipping, and surgical outcomes at the first visit after clipping.Results: The median patient age, aneurysm size, dome/neck ratio, and operative time were 63 years, 5.6 mm, 1.3, and 188 min, respectively. No cases of opening of the frontal sinus, intraoperative rupture, or clipping-related complications were observed. We successfully clipped all aneurysms completely, and no patient developed anosmia after surgery. The postoperative modified Rankin scale score was 0 in all patients at their first visit to our clinic after surgery.Conclusion: In the management of patients with unruptured cerebral aneurysms, the clipping technique should be evaluated in comparison to the minimally invasive nature and clinical outcomes of endovascular treatment.","PeriodicalId":94217,"journal":{"name":"Surgical neurology international","volume":"16 ","pages":"361"},"PeriodicalIF":0.0,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12482774/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145208819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present an alternative surgical strategy involving partial resection of the posterior portion of the glioma to reestablish CSF flow.Case description: A 3-year-old female presents with obstructive hydrocephalus. Visual acuity and fields were preserved. Initial imaging showed a third ventricular tumor with enlargement of the lateral ventricles. Due to broad differential diagnosis, endoscopic biopsy was performed, which showed pilocytic astrocytoma. A craniotomy for a transcortical transventricular approach through a tubular retractor was performed to resect the posterior portion of the glioma and open the cerebral aqueduct. The patient underwent adjuvant chemotherapy. Postoperatively, she had complete resolution of presenting symptoms and, at 20-month follow-up, she has not required any procedures for CSF diversion.Conclusion: Benefits of the reported surgical strategy of partial posterior tumor resection include lack of permanent hardware and associated complications, as well as additional tissue for molecular studies. The approach can be considered in patients with obstructive hydrocephalus in the setting of a large third ventricular pilocytic astrocytoma in which risks of attempted gross total resection are high and there is a desire to avoid shunt placement.","PeriodicalId":94217,"journal":{"name":"Surgical neurology international","volume":"16 ","pages":"359"},"PeriodicalIF":0.0,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12482772/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145208624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Treatment of Meige syndrome involves both pharmacological and surgical interventions including botulinum toxin injections, muscle relaxants, dopamine receptor antagonists, and anticholinergic drugs. Deep brain stimulation (DBS) has also been used to treat these patients with medically refractory Meige syndrome with a high degree of efficacy. Herein, we present a case of medically refractory Meige syndrome treated with bilateral globus pallidus internus (GPi) DBS with improvement of dystonia.Case description: This is a 74-year-old female diagnosed with blepharospasm 15 years ago, after she noted increased blinking frequency and difficulty keeping her eyelids open. She was initially managed with extraocular Botox injections, but her symptoms progressed and began to include shoulder shrugging, jaw clenching, and uncontrolled head turning. A diagnosis of Meige syndrome was made and the patient responded appropriately to pharmacological management with benzodiazepines, baclofen, and carbidopa-levodopa. The patient eventually developed severe dystonia secondary to her Meige syndrome diagnosis and her symptoms were now refractory to botulinum toxin injections and medications. The patient underwent DBS of the bilateral GPi. After 52 weeks of follow-up, significant improvements in involuntary blinking, squinting, photophobia, teeth clenching, and neck tightness were noted.Conclusion: DBS is a safe and effective means of treating dystonia related to Meige syndrome. Further studies are needed to elucidate optimal targeting for these patients and programming specifics for long-term outcomes.","PeriodicalId":94217,"journal":{"name":"Surgical neurology international","volume":"16 ","pages":"355"},"PeriodicalIF":0.0,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12482728/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145208716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study is to explore the long-term shunting response on gait dysfunction in patients with neurodegenerative NPH, a subtype of NPH occurring in patients with another neurodegenerative condition, as the duration of symptomatic improvement with shunting is unclear in this population.Methods: A retrospective chart review of patients undergoing evaluation for NPH at the Adult Hydrocephalus Center at Allegheny General Hospital was performed. Timed performances on two gait measures, the timed walk and timed up and go, were collected during a 2-day outpatient lumbar tap trial and on follow-up evaluation after shunt placement. Improvements over baseline were calculated at each follow-up and analyzed by years after shunt surgery. Potential sequelae of VPS such as subdural hematomas and infection during the study period were tallied.Results: Patients experienced statistically and clinically significant gait improvements within the first 6 months after surgery. Significant reductions in gait times were not found by the end of the 1st year after surgery through the remainder of the study period.Conclusion: While VPS can provide a limited period of improved gait, it was not shown that shunting can provide persisting benefit in patients with underlying progressive neurodegenerative disease. Shunting to alleviate gait symptoms should be considered on a case-by-case basis with patients and their families in alignment with care goals.","PeriodicalId":94217,"journal":{"name":"Surgical neurology international","volume":"16 ","pages":"339"},"PeriodicalIF":0.0,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12482729/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145208735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
