Prognostic factors for progression-free survival of the filum terminale ependymomas in adults

C. Dauleac et al.

Summary: Prognostic factors for the progression of filum terminale ependymomas include the quality of resection and the presence of a tumor capsule. Histological grading does not influence progression, except for anaplastic grade.

Correlation between preoperative somatosensory evoked potentials and intraoperative neurophysiological monitoring in spinal cord tumors

Jinyoung Park et al.

Summary: This study focused on the correlation between preoperative and intraoperative evoked potentials in spinal cord tumor removal surgery. Patients with prolonged preoperative somatosensory evoked potentials showed poorer intraoperative potentials, highlighting the predictive value of preSEPs for monitoring results. Additionally, anatomical factors and intraoperative SEPs were identified as prognostic factors for postoperative motor deterioration.

Effect of distortion corrections on the tractography quality in spinal cord diffusion-weighted imaging

Corentin Dauleac et al.

Summary: The study evaluated the impact of different distortion correction methods and patient geometry on the quality of spinal cord tractography rendering, according to different tractography approaches.

What is the predictive value of intraoperative somatosensory evoked potential monitoring for postoperative neurological deficit in cervical spine surgery?-a meta-analysis

Rajiv P. Reddy et al.

Summary: SSEP monitoring is highly specific but weakly sensitive for postoperative neurological deficit following cervical spine surgery. The analysis found that patients with new postoperative neurological deficits were nearly 27 times more likely to have had significant intraoperative SSEP change. Loss of SSEP signals and irreversible SSEP changes seem to indicate a much higher risk of injury than reversible SSEP changes.

Predictive Value of Transcranial Evoked Potential Monitoring for Intramedullary Spinal Cord Tumors

Sebastian Ille et al.

Summary: In this retrospective study on intraoperative neurophysiologic monitoring (IONM) during the resection of intramedullary spinal cord tumors (ISCTs) in 83 consecutive cases, IONM was found to be feasible with high sensitivity and negative predictive value, but low specificity and positive predictive value, particularly at long-term follow-up. Postoperative new transient and permanent deficits occurred in 14.5% of cases, and complications were experienced in 18.1% of patients.
