In previous studies, multitrack trajectories in deep brain stimulation (DBS) have usually been approximated. Using a geometrically more accurate method, we compared the stereotactic accuracy of DBS with multitrack microelectrode recording and awake stimulation (function group) and MRI-guided DBS (MRI group). ⋯ Multitrack DBS using intraoperative functional evaluation resulted in worse stereotactic accuracy than did MRI-guided DBS. However, track shifts in function-guided DBS can approach MRI targets effectively.

Syringomyelia is a progressive cerebrospinal fluid disorder that can lead to irreversible spinal cord injury. To date, the optimal management of syringomyelic cavities remains controversial. Multiple studies have emphasized the importance of the craniocervical decompression or shunting procedures; however, except for syrinx related to Chiari malformation, nearly one-half of patients need to undergo reoperation. The purpose of the present study was to describe a simple and efficient surgical technique and to report the long-term radioclinical outcomes. ⋯ A myringotomy tube is a simple surgical technique that seems to be an efficient and safe treatment for syringomyelic cavities.

To review the literature of spinal cord injury and stem cell therapy for large animal models and incorporate those results into an understanding of stem cell therapy for human cord injury. ⋯ Stem cell therapy is a promising therapeutic option for patients with spinal cord injury; however, the technology has many un-answered questions and further research is needed.

To determine whether fusion 3-dimensional (3D) angiography of both internal carotid arteries can better disclose vascular details in patients diagnosed with anterior communicating artery (ACoA) aneurysms by computed tomography angiography (CTA) or magnetic resonance angiography (MRA). ⋯ Fusion 3D angiography can significantly contribute to a better understanding of the complex anatomy of the anterior cerebral artery-ACoA complex, which is essential for successful treatment planning for ACoA aneurysms.

Quantitative estimates of surgical capacity and infrastructure and perceived care limitations in low-resource countries are essential baseline measures that can provide strategies for improving access to surgical care. Information about these barriers in Africa is scarce, particularly with respect to neurosurgery. We conducted a survey to better understand the unmet surgical need and resources available for the care of neurosurgery patients in Sub-Saharan Africa. ⋯ This large survey defines important self-perceived limitations to care within neurosurgery and highlights the importance of infrastructure and allied professions in this role. A clear understanding of areas of focus will enable a more efficient and sustainable response to the limitations in surgical care in low-resource areas.
