A comprehensive approach to lateral ventricular tumor resection: techniques, technologies, and outcomes

This study reviews lateral ventricular tumors (LVTs), which are rare brain lesions accounting for 0.64-3.5% of brain tumors, and the unique challenges they present due to their location and growth patterns. Once deemed inoperable, advancements in microneurosurgery, imaging, and tumor pathobiology have significantly improved treatment outcomes. This letter summarizes recent studies and key findings in the management of LVTs. Research by S.A. Maryashev et al. identified risk factors for early hemorrhagic complications following the surgical resection of lateral ventricular neoplasms, highlighting the significance of patient characteristics, tumor location, and surgical approach. The study found that factors such as gender, hydrocephalus, tumor blood flow, and Evans index correlate with a higher risk of hemorrhage, with the transcallosal approach having a greater risk compared to the transcortical approach. The utilization of navigation technologies, including fMRI, neuronavigation, and intraoperative brain mapping, has been shown to reduce surgical complications and enhance patient outcomes in the treatment of lateral ventricular meningiomas. Moreover, endoscopic and endoport-assisted endoscopic techniques have proven to be valuable in intraventricular tumor surgery, enabling minimally invasive procedures with better visualization and fewer complications. The integration of advanced surgical techniques, neuroimaging, and neurophysiological monitoring emphasizes the necessity of a multidisciplinary approach to optimize patient outcomes. To improve the study's validity and applicability, further research with larger sample sizes and advanced statistical analyses is needed. This letter advocates for the continued exploration of innovative surgical techniques and technologies to enhance the management of lateral ventricular tumors.
