Clinical Report: Feasibility and Safety of a Triple-Modality Surgical Approach
Overview
This report evaluates a novel triple-modality surgical approach for complex septated chronic subdural hematomas (CSDHs), demonstrating high feasibility and safety. The approach resulted in significant hematoma volume reduction and no recurrences in a small cohort of patients.
Background
Complex septated CSDHs present significant surgical challenges due to their high recurrence rates following conventional treatments. Traditional burr-hole drainage often fails to address the underlying mechanisms driving these recurrences, necessitating innovative surgical strategies. The introduction of a triple-modality approach aims to improve outcomes by targeting neoangiogenesis, mechanical sequestration, and localized inflammation.

Key Findings
The triple-modality approach includes MMA embolization, neuroendoscopic fenestration, and localized dexamethasone irrigation.
All patients in the study improved to a Markwalder Grade of 0–1.
No recurrences were observed in the experimental cohort (0/7), compared to a 36.3% recurrence rate in the historical control group.
The median hematoma volume reduction was greater than 95% across the cohort.
No steroid-related systemic complications or wound healing defects were reported.
Clinical Implications
The findings suggest that the triple-modality approach may significantly reduce recurrence rates in complex CSDHs compared to traditional methods. This strategy may offer a safer alternative for managing these challenging cases, particularly in elderly patients who are at higher risk for systemic complications from corticosteroids.
Conclusion
The preliminary results indicate that the triple-modality surgical approach is both feasible and safe, with promising outcomes in terms of hematoma resolution and recurrence prevention. Further studies with larger cohorts are warranted to validate these findings.
