Chronic subdural hematomas (CSDHs) are common in the elderly population and patients taking antiplatelet/anticoagulation medications. Middle meningeal artery (MMA) embolization has become an adjunctive treatment to observation and surgery. Despite many embolization techniques, best practices for optimal CSDH resolution remain unknown. ⋯ Distal penetration of embolic material, particularly n-butyl cyanoacrylate, into the falx may lead to more rapid improvement of CSDH.

Direct stimulation and diffusion tensor imaging/tractography are established techniques that assist in complex surgery for lesions in the eloquent area of the central nervous system. ⋯ This study further supports the paradigm for continuous CST monitoring and mapping through direct brainstem stimulation. The relationship between stimulation intensity and DS-to-T in brainstem surgery could help surgeon's better estimate the safe edge intraoperatively.
