Generally, the sacrifice of arteries that perfuse normal brain parenchyma is avoided. However, there are instances when it is necessary to take certain distal arteries to adequately perform tumor resections or secure vascular lesions. Deciding whether the sacrifice of such arteries is safe can be difficult. ⋯ Although this is a limited experience and cannot prove the safety of arterial sacrifice in all situations, our series demonstrates the potential usefulness of ICG videoangiography in assessing collateral arterial flow before sacrifice of distal cerebral arteries.

Roughly one-third of the world's nearly 7 billion people are covered by approximately 1/20 of its neurosurgeons. Neurosurgeons in the more developed countries have a moral obligation to increase access to neurosurgical care for the rest of the world. This can be achieved most effectively through neurosurgical education. ⋯ In Uganda, we have successfully educated one to save a relative few. Our aim is to educate a few to save many. Such a disease-specific approach may provide a useful strategy for increasing access to care for other common, treatable neurosurgical conditions in resource-poor settings.

The establishment of neuroendoscopy has been one of the major achievements in neurosurgery in the last 2 decades. The use of the endoscope increases efficacy and safety in each procedure. ⋯ A dedicated endoscopic operating room should provide workflow optimization, ergonomic solutions, and highest safety standards for the patient.

This study sought to identify genes in nontypical meningiomas with gains in copy number (CN) that correlate with earlier age of onset, an indicator of aggressiveness. ⋯ Low levels of amplification for selected oncogenes in invasive/atypical/anaplastic meningiomas were higher in younger adults, with the CN gains potentially underlying biological aggressiveness associated with early tumor development.
