Moderate-to-severe traumatic brain injury (TBI) is a major source of morbidity and mortality in elderly patients. Little is known about long-term mortality in elderly patients following mild, nonfatal TBI and how the injury mechanism predicts survival. This study aimed to compare long-term mortality in elderly patients with mild TBI and traumatic subdural hematoma (tSDH) due to ground-level fall (GLF) versus those with TBI and tSDH due to another cause (i.e., non-ground-level fall [nGLF]). ⋯ Elderly patients with mild TBI and tSDH due to GLF have significantly higher long-term mortality than patients with injuries due to nGLF.

Here, we evaluate the evolution and growth of global neurosurgery publications over time, further focusing on the contributions and impact of authors in low- and middle-income countries (LMICs). ⋯ Despite recent growth, the number of global neurosurgery publications arising from LMICs pales in comparison to those from HICs. Collaborative efforts between certain HICs and LMICs have likely contributed to the observed increase in LMIC author independence over time.

Primary spinal cord astrocytomas are rare, fatal, and poorly studied. ⋯ Outcomes worsen with higher grades and lead to difficult postoperative periods. Clinicians should be vigilant for thromboembolic complications. Further research is needed to understand these rare tumors.

In this study, a large diameter visible trephine was designed and used in percutaneous endoscopic lumbar interbody fusion to increase endoscopic bone decompression efficiency. Large diameter visible trephine-related technical notes and preliminary clinical experience are described. ⋯ For percutaneous endoscopic lumbar interbody fusion, the large diameter visible trephine is a safe and efficient endoscopic bone decompression tool under fluoroscopic guidance.

Some data suggest a vasodilatory effect of sympathetic blockade in patients with aneurysmal subarachnoid hemorrhage, but the effect on medium-sized intracranial arteries remains unclear. We report the results of serial cerebral angiography to study the cerebral vasodilatory effects of percutaneous inferior sympathetic ganglion block in 2 patients. ⋯ We observed vasodilation in medium-sized intracranial arteries ipsilateral to the percutaneous inferior sympathetic ganglion block as early as 1 minute post treatment and persisting for at least until 30 minutes post blockade.
