The occipital transtentorial approach (OTA) is a very useful but challenging approach to expose the pineal region because the deep-seated arachnoid membranes usually fold and extend over the great vein of Galen (GVG), leading to dense and poor visibility. In addition, the practical aspects of arachnoid anatomy are not well understood. We aimed to develop a safe surgical procedure for the OTA according to the practical aspects of arachnoid anatomy. ⋯ A 2-layered arachnoid structure interposes the GVG from above and below the tentorium. The arachnoid membrane below the tentorium can be peeled off bluntly from the GVG to the attachment bundle limited by the penetrating veins. This detachment technique is useful for safe enlargement of the surgical field for the OTA.

The demand of thrombectomy treatment for acute ischemic stroke increased dramatically in the United States after the publication of 5 pivotal trials in 2015. The impact of call burden on career satisfaction and burnout in neurointerventionalists has not been explored. ⋯ The burden of stroke call has strong implications for career satisfaction and burnout in neurointerventionalists. This model can be used by hospitals, departments, and physician groups to better conceptualize conditions that facilitate burnout and attrition. Changes to hospital management practices and culture may be the most productive focal areas for intervention.

The endoscopic endonasal transcavernous (EET) approach is an increasingly popular approach for the cavernous sinus and surrounding structure lesions as well as a surgical corridor to pre-mesencephalic cisterns. This endoscopic study describes the main intracavernous branches of the internal carotid artery, providing nuances to improve the safety of this approach. ⋯ The MHT is a highly prevalent intracavernous branch, with 7 identifiable patterns based on DMA morphology and branch combination. This knowledge could guide surgeons in performing a safer EET approach.

The Council of State Neurosurgical Societies surveyed neurosurgeons applying for oral board certification in 2008 to assess their preparedness to practice. This survey was repeated in 2013 for a subsequent group of board applicants to evaluate the quality of neurosurgery training and identify opportunities for improvement. ⋯ The 2013 survey suggests that candidates for board certification in neurosurgery perceive themselves to be adequately prepared to independently perform nearly all neurosurgical procedures. However, additional work is required to optimize neurosurgery training in endovascular procedures and the socioeconomic aspects of neurosurgery practice.
