Though frequently effective in the management of medically refractory seizures, epilepsy surgery presents numerous challenges. Selection of the appropriate candidate patients who are likely to benefit from surgery is critical to achieving seizure freedom and avoiding neurocognitive morbidity. ⋯ Various strategies can be employed either to eliminate the epileptic focus or to modulate network activity, including resection of the focus with open surgery or laser interstitial thermal therapy; modulation of epileptogenic firing patterns with responsive neurostimulation, deep brain stimulation, or vagus nerve stimulation; or non-invasive disconnection of epileptic circuits with focused ultrasound, which is also discussed in greater detail in the subsequent chapter in our series. We review several challenges of epilepsy surgery that must be thoughtfully addressed in order to ensure its success.

Management of small unruptured aneurysms is controversial. Small aneurysms and those with low PHASES scores are often observed. The primary aim of this study was to assess whether the PHASES score classified the patients with subarachnoid hemorrhage as high risk for rupture. ⋯ PHASES is inadequate in management of unruptured aneurysms because it fails to identify many patients at risk for subarachnoid hemorrhage. A more nuanced assessment of rupture risk should be undertaken.

Never in history has the fabric of African neurosurgery been challenged as it is today with the advent of the novel coronavirus identified in 2019 (COVID-19). Even the most robust and resilient neurosurgical educational systems in the continent have been brought to their knees with neurosurgical trainees and young neurosurgeons bearing the brunt. ⋯ This unfortunate event presents an innovative opportunity for neurosurgical education in Africa. Herein, we detail the framework of an online neurosurgical education initiative to advance the education of African residents and young neurosurgeons during and after the COVID-19 pandemic.

Aneurysms associated with brain arteriovenous malformations (AVMs) represent a hemorrhage risk in addition to that of the AVM nidus. In high-risk or unresectable cases, targeted treatment of an aneurysm causing hemorrhage may effectively decrease future hemorrhage risk. The objective of this report is to describe our series of patients with intraventricular AVM-associated aneurysms treated surgically. We highlight technical nuances of the surgical approaches to aneurysms in the lateral and third ventricles. ⋯ Ruptured intraventricular aneurysms associated with brain AVMs can be treated surgically to reduce the risk of rebleeding in patients in whom the aneurysms are not accessible to endovascular treatment and in which the AVM nidus may not be safely resected.

Comparative Study
Subdural Drain vs Subdural Evacuating Port System for the Treatment of Non-Acute Subdural Hematomas: A Single-Center Retrospective Cohort Study.
Subdural drain (SDD) and Subdural Evacuating Port System (SEPS) are bedside options for management of nonacute subdural hematomas (SDHs). These interventions have not been compared with each other. Our objective is to compare the need for second bedside procedure, need for craniotomy, complication rate, and other outcomes related to bedside drainage of SDH with SDD or SEPS. We hypothesized that SDD would be associated with superior outcomes to SEPS. ⋯ SEPS was associated with higher risk for need of second bedside procedure and longer intensive care unit and hospital length of stay than SDD, although not increased need for craniotomy. Additional studies are needed to confirm our findings and determine if SDD may be more effective than SEPS for the treatment of nonacute SDH.
