Background: Middle meningeal artery (MMA) embolization has been proposed as a treatment of chronic subdural hematoma (CSDH). The benefit of the procedure has yet to be demonstrated in a randomized controlled trial. We aim to assess the efficacy of MMA embolization in reducing the risk of CSDH recurrence 6 months after burr-hole surgery compared with standard medical treatment in patients at high risk of postoperative recurrence.

- Primary hemifacial spasm (pHFS) is a movement disorder caused by a conflict between blood vessels and the facial nerve, and microvascular decompression (MVD) is the most effective treatment.
- A study of 200 patients who underwent MVD revealed that 7.5% experienced recurrence, with higher rates linked to multiple and AICA-related neurovascular conflicts.
- Complications included facial palsy (2.5%), hearing loss (9.0%), and dizziness (2.5%), all worsened by a longer duration of symptoms before treatment, but a second MVD can yield favorable results without significantly increasing complications.
Objectives: Convexity spontaneous subacute subdural hematoma (CSSSH) frequently relapse after one or more surgical drainages. This may be due to spontaneous intracranial hypotension (SIH), for which the gold standard treatment is the epidural blood patch. In this study, we report 4 cases of refractory CSSSH treated with rescue epidural saline patch, although history and imaging studies showed no evidence of SIH.

Third and lateral ventricle tumors require surgery that may lead to cognitive impairment. Our objective is to compare the long-term consequences of a transcortical transfrontal approach and an interhemispheric transcallosal approach on corpus callosum and frontal white matter tracts degeneration.

In our neuroscience institution, the challenge was to continue to manage usual neurological emergencies as well as the influx of COVID-19 patients.
Methods: We report the experience of an ethical consulting unit to support care clinical decisions during the first wave of the pandemic (March 16 to April 30, 2020).
