Neurosurgical Review

Central nervous system tumors, classified by the WHO into four grades based on their aggressiveness, present significant challenges in treatment, particularly low-grade gliomas (LGGs) which, despite their slower growth, can progress to high-grade gliomas. Lucca B. Palavani and colleagues evaluated the efficacy and safety of SBT I-125 brachytherapy for LGMs in a systematic review and meta-analysis of 20 studies involving 988 patients. The analysis revealed an overall complication rate of 10%, with headaches and cyst formation being the most frequent issues...

With the increasing complexity of intracranial aneurysm surgery and the reduced opportunities for hands-on training, there is a need for effective simulation-based training methods. This systematic review examines 26 studies on various simulation training approaches for intracranial aneurysm clipping, including ex vivo methods, virtual reality platforms, and 3D-printed models. The review evaluates these methods based on their effectiveness, realism, usability, and validation, highlighting that current simulation models are heterogeneous and lack standardization...

This letter discusses major aspects of the research "Superb Microvascular Ultrasound as a Promising Non-invasive Diagnostic Tool to Assess Ventriculoperitoneal Shunt System Function: A Feasibility Study." While the study shows great promise in adopting superb microvascular imaging (SMI) for non-invasive evaluation of ventriculoperitoneal shunt (VPS) systems, some limitations are noted. These include the small patient group, which focusses primarily on adult patients with programmable shunts, limiting the generalisability of the results...

Bioactives derived from marine sources are opening up new therapeutic opportunities for neurosurgery. These include tissue regeneration, neuroprotection, and infection control. These molecules derived from extreme marine conditions have generated new modes of action, for example, selective inhibition of voltage-gated ion channels and influencing pathways of neuroinflammation. Representative examples include chitosan for nerve regeneration, conotoxins for pain modulation, and fucoidan for neuroprotection. Despite therapeutic promise, major challenges remain: those of sustainable sourcing and regulatory validation...

This study aimed to systematically review and compare the efficacy and safety of anterior cervical controllable antedisplacement and fusion (ACAF) versus anterior cervical corpectomy and fusion (ACCF) in treating ossification of the cervical posterior longitudinal ligament (OPLL), focusing on surgery-related indicators and postoperative outcomes. This review was conducted and reported in accordance with the Cochrane Handbook for Systematic Reviews of Interventions guidelines and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting standards...

Changes in local cerebral blood flow (CBF) are a major cause of transient neurological events (TNEs) after revascularization for moyamoya disease (MMD); however, the influence of preoperative collateral pathway development on TNEs has not yet been investigated. This study included 28 hemispheres from 28 consecutive patients with MMD who underwent surgical revascularization, including a superficial temporal artery (STA) to middle cerebral artery (MCA) bypass, between January 2014 and March 2022. The collateralization pathways included the anterior communicating artery (AcomA) collaterals, posterior communicating artery (PcomA) collaterals, transdural collaterals, posterior pericallosal anastomosis, lenticulostriate anastomosis, thalamic anastomosis, and choroidal anastomosis...

This letter provides valuable insights on the recently published article titled "Efficacy of Subthalamic Deep Brain Stimulation Programming Strategies for Gait Disorders in Parkinson's Disease: A Systematic Review and Meta-Analysis." While commending the authors comprehensive review, I suggest future research focus on standardizing gait disorder classifications, conducting long-term studies to assess the durability of DBS effects and exploring adaptive DBS systems for dynamic real-time programming. Additionally, integrating advanced neuroimaging techniques could enhance our understanding of neural connectivity changes post-DBS...

Fincher syndrome is an exceptionally rare neurological problem which is characterized by simultaneous occurrence of spinal cord tumor and spinal subarachnoid hemorrhage. The article "Fincher syndrome: insights into a rare neurosurgical condition" explains about the pathophysiology, disease diagnosis, and possible treatment procedures of Fincher syndrome. Deep understanding about the syndrome will be useful to physicians and researchers for prompt detection and timely intervention of this rare condition.

INTRODUCTION: Delineating subthalamic nucleus (STN) boundaries using microelectrode recordings (MER) and trajectory history is a valuable resource for neurosurgeons, aiding in the accurate and efficient positioning of deep brain stimulation (DBS) electrodes within the STN. Here, we aimed to assess the application of artificial intelligence, specifically Hidden Markov Models (HMM), in the context of STN localization. METHODS: A comprehensive search strategy was employed, encompassing electronic databases, including PubMed, EuroPMC, and MEDLINE...

OBJECTIVE: The purpose of this study was to analyze the clinical outcomes and malignant progression of tumors in patients who underwent reoperation for recurrent solitary fibrous tumors (SFTs) and hemangiopericytomas (HPCs). METHODS: We identified 48 patients who underwent reoperation because of tumor recurrence at Tangdu Hospital between January 2010 and December 2021 and analyzed the clinical outcomes, namely, the rate of gross total resection (GTR), progression-free survival (PFS), overall survival (OS), malignant progression of tumors and radiotherapy...
