As endovascular neurosurgery techniques continue to evolve, medical students in the United States have widely varying exposures to the field, particularly with respect to opportunities for hands-on experiences. Current medical school curricula could benefit from a novel and adaptive course on vascular neurosurgery to increase student exposure earlier in their training. ⋯ An interactive course on vascular neurosurgery may be an effective vehicle to provide medical students with exposure to the field and the opportunity to learn the fundamentals.

The aim of this study is to determine the maximum loss of median and ulnar nerve substances that can be treated by direct suture in elbow flexion and to quantify this elbow flexion. The other objective is to determine the participation of the wrist position in this direct suture in elbow flexion. ⋯ The results of this first anatomical study clarified the conditions for direct suturing of ulnar and median nerve defects in the flexed elbow position and flexed wrist position. This is an approach to consider for limited nerve defects to the elbow or when allograft harvesting is to be avoided.

Over the last decade, simulation models have been increasingly applied as an adjunct for surgical training in neurosurgery. We aim through a practical course at a national neurosurgical conference to evaluate 3D non-cadaveric simulation models along with augmented reality for learning and practicing the pterional craniotomy approach among a wide variety of participants including medical students, neurosurgery residents, and attending neurosurgeons. ⋯ Simulation model combining augmented reality with physical simulation for hybrid experience can be a promising and valuable tool especially for medical students or early career neurosurgical residents.

Case Reports
Cerebrofacial Venous Metameric Syndrome Mimicking Vein of Galen Aneurysmal Malformation.
Cerebrofacial venous metameric syndrome (CVMS) is a complex low-flow vascular malformation affecting bone and soft tissues including brain, dura mater, and eye. We show images of CVMS in an 18-month-old boy presenting facial venous malformations, developmental venous anomalies, dural sinus malformations, and dilated great cerebral vein, suggesting a vein of Galen aneurysmal malformation. Although Sturge-Weber syndrome is the most known form of CVMS, its presentations are variable and include several venous malformations. Recognizing the various manifestations of CVMS is necessary for adequate screening, treatment, and follow-up.

A plethora of studies has substantiated the remarkable clinical efficacy of anterior cervical discectomy and fusion (ACDF) in the treatment of cervical spondylotic myelopathy.1,2 This procedure effectively removes the posterior osteophytes and protruding nucleus pulposus, achieving direct decompression of the spinal cord and effectively alleviating compression symptoms. Concurrently, by distracting the intervertebral space, ACDF contributes to the restoration of the physiological curvature of the cervical spine. However, several pressing issues remain to be addressed during the surgical process. ⋯ Assisted by 3D microscopy, ACDF surgery offers a high-definition visual field that enhances precision, thereby reducing procedural risks and improving clinical outcomes. This technology alleviates the physical strain on surgeons, fosters collaborative teamwork, and facilitates educational exchanges. With a relatively short learning curve, 3D microscopy significantly enhances the safety and efficiency of ACDF procedures.
