Decisions to treat unruptured intracranial aneurysms remain challenging, as the risk of rupture needs to be balanced with risk of intervention. In 2015, the Unruptured Intracranial Aneurysm Treatment Score (UIATS) was introduced to assist physicians in the decision making process. As its reliability is still debated, we retrospectively applied UIATS to a multicenter cohort of aneurysmal subarachnoid hemorrhage patients to test its performance in suggesting treatment in patients with known natural history. ⋯ In our study, UIATS would have failed to provide a clear recommendation to treat in up to 72.6% of patients whose aneurysm eventually ruptured. In agreement with previous reports, we provide additional evidence that some unruptured intracranial aneurysms may elude UIATS sensitivity. Further long-term prospective studies are necessary to assess UIATS reliability in real-world clinical practice.

Clinical Trial
Long-term independence in older patients with aneurysmal subarachnoid hemorrhage in the Barrow Ruptured Aneurysm Trial (BRAT).
Older patients have a higher risk for poor neurological outcomes following aneurysmal subarachnoid hemorrhage (aSAH). This study compared functional independence in older versus younger patients with aSAH and compared endovascular coiling with microsurgical clipping in the older cohort. ⋯ Patients ≥65 years old with aSAH are at increased risk for poor neurological outcomes compared with younger patients. Greater independence was observed in older patients after microsurgical clipping than after endovascular coiling at long-term follow-up.

Comparative Study
Effectiveness of two types of drill templates for anterior cervical transpedicular screw (ATPS) placements: a comparative study.
To evaluate effectiveness of regular and modified drill templates used to guide cervical anterior transpedicular screw (ATPS) placement. ⋯ Compared with regular drill templates, modified drill templates can provide higher accuracy and stronger trajectory control in ATPS insertions.

Comparative Study
Comparison of operating microscope and exoscope in a highly challenging experimental setting.
The use of a digital three-dimensional (3D) exoscope system in neurosurgery is increasing as an alternative to the operative microscope. The objective of this study was to compare a digital 3D exoscope system with a standard operating microscope as a neurosurgical visualization tool in a highly challenging experimental setting. ⋯ In a highly challenging experimental setting, comparable procedural quality was found for the microscope and the 3D exoscope. Each visualization tool had advantages and disadvantages. Over time and with technologic advances, the digital 3D exoscope may become the main operative visualization system in microneurosurgery.

We aim to provide a thorough description of the efforts and outcomes of the Co-Pilot Project in Ukraine, which facilitates neurosurgical collaboration between American and Ukrainian physicians. ⋯ Profound disparities in neurosurgical care exist globally, which has led to the formation of collaborative relationships between physicians from various countries. We hope that the work of the Co-Pilot Project in Ukraine can serve as a template for effective international neurosurgical collaboration in other low-to-middle-income countries.
