Electric cortical stimulation (ECS) has been the gold standard for intraoperative functional mapping in neurosurgery, yet it carries the risk of induced seizures. We assess the safety of focal cortical cooling (CC) as a potential alternative to ECS. ⋯ CC when used as an intraoperative mapping technique is safe and may complement ECS.

Degenerative lumbar spinal stenosis (DLSS) carries a high risk of morbidity and represents a financial burden to society. A late diagnosis can lead to severe disability. Although lumbar decompressive surgery has been widely used worldwide, the proper preoperative factors to define the ideal candidates for decompression are missing. ⋯ Our findings have indicated that the ideal candidate for surgery will have the following preoperative characteristics: Schizas grade D, no signs of peripheral polyneuropathy, body mass index <30 kg/m2, symptom duration of <2 years, gait autonomy <100 m, no radicular deficits, 1 level of stenosis, and an American Society of Anesthesiologists score of 1, 2, or 3.

Subdural hematoma (SDH) is the most common form of traumatic intracranial hemorrhage. Orlando and colleagues derived a prediction tool for neurosurgical intervention, the "Orlando Tool," consisting of (a) maximum thickness of hematoma, and (b) presence of acute-on-chronic (AOC) hematoma. This study externally validated the Orlando Tool. ⋯ The Orlando Tool accurately predicts neurosurgical intervention in patients with isolated, traumatic SDH and preserved consciousness.

In this study, we sought to characterize contemporary trends in cost and utilization of spinal cord stimulation (SCS). ⋯ Despite a declining contemporary trend in inpatient SCS, an increase was noted in admission costs and hospital charges. A significant declining trend was noted in revision SCS implantations due to device-related complications.

Transradial access has been used increasingly for diagnostic cerebral angiography and neurointerventions. This requires development of a new skillset. Forming the Simmons catheter to catheterize the cerebral vessels is the most fundamental. Patient anatomy can complicate the formation of the Simmons catheter and the success of the procedure. The aim of this paper is to identify and describe the techniques that can be used transradially to facilitate the formation of the Simmons catheter for catheterization of the cerebral vessels. ⋯ Transradial artery access has become increasingly common in cerebral angiography and neurointerventions. We describe techniques used for the formation of the Simmons catheter, a fundamental skill necessary for transradial cerebral angiogram or neurointervention.
