The optimal timing for surgery for patients with spinal cord injury without radiographic evidence of trauma (SCIWORET) remains unclear. This is especially true in the elderly, given that most studies are done with younger patients to avoid age-related comorbidities. We aimed to compare the efficacy of early (<24 hours postinjury) and late (>24 hours postinjury) surgery in patients with SCIWORET aged ≥65 years. ⋯ The present study indicated that early surgery within 24 hours of injury for elderly patients with SCIWORET could lead to more favorable neurologic improvements. We believe that chronological age alone should not be considered sufficient justification to deny patients early surgical decompression for SCIWORET.

The authors describe the application of a new exoscope that offers 3-dimensional (3D) visualization in cranial and spinal neurosurgery in detail. ⋯ The 3D-exoscopic system is safe and effective tool to perform spinal procedures and less demanding cranial procedures. The image quality and 3D visualization were comparable with the operating microscope. The technique harbors the unique advantage of excellent comfort for the involved surgical team during the procedure.

The number of patients treated with novel oral anticoagulants (NOACs) is increasing. Despite growing clinical relevance, guidelines on the perioperative management of neurosurgical patients treated with NOACs are still lacking. The aim of this study was to analyze the occurrence of postoperative bleeding events and factors that might influence bleeding rates in these patients. ⋯ The postoperative bleeding rate in patients undergoing cranial surgery treated with NOACs was 13.3%. A shorter preoperative discontinuation time seems to have a significant effect on bleeding rate. Further studies evaluating the management and postsurgical outcomes of these patients are warranted.

Case Reports
A case of familial moyamoya disease presenting 10 years after the initial negative MR screening in childhood.
Both genetic and environmental factors are considered to contribute to the onset of moyamoya disease, but the exact mechanism has not yet been clarified. Furthermore, the typical time course of progression to vessel occlusion has not been established, even in the genetically high-risk population. ⋯ We show a case of familial moyamoya disease diagnosed 10 years after the magnetic resonance imaging screening in childhood. We must carefully consider when, how, and for whom screening for moyamoya disease should be performed, taking into account familial history of the disease.

Seizure is the second-most common presentation in patients with arteriovenous malformations (AVMs) and superimposes a significant burden on pediatric patients. Postoperative seizure risk in unruptured AVMs is underreported in the pediatric AVM literature. We aimed to characterize and identify predictive factors for postoperative seizures in this study. ⋯ Surgery may eliminate most seizures with low risk of inducing de novo seizures in pediatric patients with unruptured AVM. Predictive factors for postoperative seizures included large AVM size and temporal location. For selected unruptured AVMs with small size and nontemporal location, consideration of surgery as primary treatment for persistent seizures is a reasonable option.
