These tumors are primarily supplied by branches of the choroidal artery group arising from the inferior side. To access the vascular pedicles, the shortest and most direct surgical corridor to the trigone is generally preferred, making the transcortical transparietal approach a common choice. However, this approach carries a high risk of damaging critical subcortical white matter tracts. Injury to these tracts can result in language deficits (on the left side), spatial neglect syndrome (on the right side), as well as sensory disturbances and visual field deficits. To minimize disruption to these white matter tracts, the high parietal approach is often recommended. However, this technique presents its own challenges, particularly in achieving early control of arterial feeders, which becomes even more critical in larger trigonal tumors. Case Presentation We present the case of a 13-year-old boy with a large trigonal intraventricular tumor. Given his lack of significant symptoms and his young age, our surgical strategy focused on maximizing the preservation of his neurological function. We developed a novel combined transtemporal and high parietal approach. The small transtemporal approach allows early devascularization, followed by the high parietal approach, which facilitates tumor resection while preserving the vital white matter tracts along the lateral wall of the trigone. Conclusion We propose a novel combined technique that offers a balance between optimal tumor resection and functional preservation, particularly in cases of large and hypervascularized trigonal tumors.</p>","PeriodicalId":54631,"journal":{"name":"Pediatric Neurosurgery","volume":" ","pages":"1"},"PeriodicalIF":1.3,"publicationDate":"2025-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145245540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Johns Hopkins Adjusted Clinical Groups (JHACG) frailty and the Elixhauser Comorbidity Index (ECI) have been used independently in adult brain tumor patients to identify patients at increased risk for detrimental outcomes.

The only recourse for many of these individuals is neurosurgery to reduce seizure burden, either by resecting or ablating the cerebral source or modulating it with a stimulator device. In either case, a thorough pre-surgical evaluation is required to identify brain regions of interest and construct an appropriate surgical plan. The scope of this evaluation has grown rapidly over the years as new and refined techniques have emerged. The aim of this article is to condense the most salient points regarding investigational tools used commonly in this process and provide a framework from which epilepsy management providers can tailor their own epilepsy surgery pathway.
