Syringomyelia Resolution Following Chiari Surgery: A Novel Scale for Communication and Research

Syringomyelia Resolution Following Chiari Surgery: A Novel Scale for Communication and Research

Neurosurgery 88( 1) 2021: 131–139 The pathophysiological connection between Chiari malformation and syringomyelia is accepted. Debate remains, however, how can we best define changes in syringomyelia following surgery. OBJECTIVE: To introduce a grading system focusing on syrinx reduction based on routinely and reproducible radiological information, and provide a suggestion of the application of…

Peritumoral Edema/Tumor Volume Ratio: A Strong Survival Predictor for Posterior Fossa Metastases

Peritumoral Edema/Tumor Volume Ratio: A Strong Survival Predictor for Posterior Fossa Metastases

Neurosurgery, Volume 85, Issue 1, July 2019, Pages 117–125

Twenty percent of all brain metastases (BM) occur in the posterior fossa (PF). Radiotherapy sometimes associated with surgical resection remains the therapeutic option, while Karnovsky performance status and graded prognostic assessment (GPA) are the best preoperative survival prognostic factors.

OBJECTIVE: To explore the prognostic role…

Posterior fossa meningiomas: perioperative predictors of extent of resection, overall survival and progression-free survival

Acta Neurochirurgica (2019) 161:1003–1011

Posterior fossa meningiomas (PFMs) often represent surgical challenges due to their proximity to neurovascular structures. Factors predicting the extent of resection (EOR), overall survival (OS), and progression-free survival (PFS) were identified and integrated in a prediction tool to offer evidence-based personalized therapeutic strategies.

Methods All…
