Intracranial hemorrhage (ICH) is considered an emergency that requires rapid medical or surgical management. Previous studies have used artificial intelligence to attempt to expedite the diagnosis of this pathology on neuroimaging. However, these studies have used local, institution-specific data for training of networks that limit deployment of across broader hospital networks or regions because of data biases. ⋯ We demonstrate an effective neural network trained on completely open data for screening ICH at an unrelated institution. This study demonstrates a proof of concept for screening networks for multiple sites while maintaining high efficacy.

The Importance of the Temporary Clip Removal Phase on Exposure to Hypoxia: On-Line Measurement of Temporal Lobe Oxygen Levels During Surgery for Middle Cerebral Artery Aneurysms.
Most studies concerning intraoperative temporary arterial occlusion overlook the period between and after clip placement. ⋯ During the clip removal phase, the brain tissue is still exposed to oxygen levels that are significantly below the baseline, reverting through a singular, dynamic process. Therefore, it must be regarded by surgeons with the same degree of attention as its counterpart.

Telemedicine has become indispensable in today's health care because of the recent ongoing COVID-19 crisis. Although it has been beneficial in coping with the pandemic, there is still much uncertainty as to whether it will have a permanent role in treating spine patients. Some of the ongoing legal challenges include patient confidentiality, liability coverage for treating healthcare workers, and financial reimbursements by insurance companies. ⋯ Moreover, without parity and uniformity, the incentive to offer telehealth services decreases. There may be a need for modifications in the law, insurance policies, and medical malpractice coverage to strengthen their support to telemedicine usage. As spine surgeons become more familiarized with the telemedicine framework, its role in patient care will likely expand.

Maintaining the patency of extracranial-to-intracranial (EC-IC) bypass is critical for long-term stroke prevention. However, reports on the factors influencing long-term bypass patency and quantitative assessments of bypass patency are limited. ⋯ Double anastomoses and cilostazol resulted in long-term STA blood flow preservation. No recurrence of cerebral infarction was noted in either STA hypoperfusion or occlusion cases.
